Pathfinder Conversion of Symbionts

[Deviston]

NOTE!!! This was done as a entry to a competition, and the theme was video games. So all symbionts have that word changed to "seru". A rose by any other name still gives you benefit when it attaches.


Legacy of Legaia

The knowledge of where seru come from is unknown in recent times. As far as those who know of them are concerned, seru have always been about in the world. However, this is not so. Seru came into the material plane untold eons ago from a plane adjacent to the material. For centuries they were outsiders, and then true to their evolving nature they slowly became a part of the material world. Now most seru are aberrations, and if their evolution continues, they may in fact become even more attuned to the material plane and eventually become a natural beast. Regardless of past or future, seru are here now and many take advantage of their utility even with the stigma that comes with a creature that prefers to take sustenance from another. The seru come in many shapes and with many different abilities. As such, very few people cannot find a seru that fits their needs or desires.

There are several different types of seru as well. The basic seru is known to most men. To some, another type called the ra-seru is known. This is an evolved seru with greater purpose and power. For those who seek to manipulate and control the creatures, a magically augmented sim-seru has been created. Wholly evil due to the magics that have warped their minds, these creatures are almost always subservient to their vile masters. Some have even rumored to have seen or heard tale of a sim-ra-seru, a being whose evolution was propelled forward with magic and purpose is considered on par with demons or devils in its evil intent.

Seru Subtype

Spoiler

Show

Seru are types of creatures, usually aberrations, that are attach themselves to other creatures, bridging the gap between creature and magical item. While by themselves, seru do not pose much of a threat, thus their CR is usually quite low. However, when attached to a host, they augment the abilities of the host similar to a magical item. Unless otherwise noted in a creature's entry, all seru possess the following traits.

Seru Traits: When joined with a host, a seru gains a number of benefits. It acts on its host’s turn each round, regardless of its own initiative modifier. It is not flat-footed unless its host is, and it is aware of any danger its host is aware of. If a seru is attached onto a visible part of the host creature’s body, opponents can attack the seru itself instead of its host creature. This works the same way as attacking an object: The seru gains the benefit of the host’s Dexterity modifier to AC instead of its own, the host’s CMD, and gains any deflection bonus to AC the host has as well. Its own size modifier and natural armor bonus, if any, apply. Attacking a seru instead of its host provokes an attack of opportunity from the host. A seru never takes damage from attacks directed at the host. Like a worn magic item, a seru is usually unaffected by spells that damage the host, but if the host rolls a 1 on its saving throw, the seru is one of the “items” that can be affected by the spell (see Items Surviving after a Saving Throw, in the Pathfinder Core Rulebook). A seru uses its host’s base saving throw bonuses if they are better than its own as well as benefits from any immunities, resistances or special defenses that the host has.
Important Exception: Should the host be targeted by an effect that reacts differently based on creature type or subtype, the host and seru use the same resistance (Armor class, saving throw, caster check, percentages, etc), but suffer the effect separately. Effects that specifically target only the seru's creature type (usually aberration) are useful for removal seru from their hosts.

Share Spells (Su): Any spell the host creature casts on itself automatically also affects the seru. Additionally, the host can cast a spell with a target of “You” on its seru instead of on itself. Likewise, a seru can choose to have any spell or spell-like ability it uses on itself also affect the host creature, and can cast a spell with a target of “You” on its host instead of on itself. The host and seru can share spells even if the spells normally do not affect creatures of the host’s or seru’s type. Spells targeted on the host by another spellcaster do not affect the seru, and vice versa.

Ego: All seru have an Ego score, similar to an intelligent magical item. Likewise, all seru have an alignment and some kind of personal goal. Should a seru and its host come into conflict over these goals or in general principle of alignment, the host must make a Will save with a DC equal to the seru's Ego score with success or failure handled as per the Intelligent Magic Item rules.

Attachment (Ex): Attaching or removing a seru is an invasive process, but one that the seru does instinctively to a willing or helpless host that is in the same square as it. Attaching a seru takes a full-round action that provokes an attack of opportunity.
Important Exception: Whenever the seru takes enough damage to be killed, it may (as a free action) require the host to make an Ego save. If the seru wins the save (or if the host is willing) the seru deals its symbiosis cost (see below) to the host to negate the damage that would have killed the seru.

Host Benefits (Ex, Su or Sp): When a seru is attached to a host, the host gains a number of benefits, as detailed by the specific seru. These benefits can be extraordinary, supernatural or spell-like, as detailed by the specific seru.

Symbiosis Cost : Attaching or removing a seru deals a certain amount of ability damage to the host that heals at normal rates. After the initial damage, the biochemistry of the host creature and seru balances and no further damage occurs unless the seru is removed or unless otherwise noted. Removing a seru against its will requires the host to make a successful Will save against the Ego score and a full-round action that provokes and attack of opportunity, or requires a Heal check (DC 25) and 1 hour for someone to remove without killing the seru and dealing 5 times the normal symbiosis cost to the host.

Item Slot: While attached, the seru usually counts as a body slot for the purposes of other magical items. Due to the fact that seru are attached to their host, they cannot be stolen (through the Steal maneuver or Sleight of Hand use) and the DC to disarm, sunder or otherwise remove a seru is increased by a +10 circumstance bonus.
Special: Some seru have a (partial) after their body slot descriptor. These seru can be worn multiple times, one for each of the body slot the host has. For example, a human commoner has two hands. He may wear an eldritch claw and a flame glove (as each takes up a partial hands slot) but could not wear either in combination with angel claws (as angel claws take up the entire hands slot).

Telepathy (Ex): While attached, a seru can communicate telepathically with their host if their host has a language.

Internal Items: Seru fall under the item category of internal items and have certain rule for being created. Serus are grown, not crafted, although they have the some of typical requirements for item construction. Growing a seru requires a willing or helpless living aberration. The aberration in question suffers 1 point of Constitution drain per seru being grown at a time and has the sickened condition for the time required to grow the new seru. Seru Half-bloods only suffer the Constitution drain. If the Constitution drain or the sickened condition is removed while the seru is being grown, it dies and the effort (and gold pieces) is wasted.

Caster Level: The appropriate caster level to grow the seru; Price: The price of the seru, in gold pieces.
Requirements: Craft Seru; Skill: Knowledge (dungeoneering) ranks and DC to make the seru; Cost: 1/2 the Price in gold pieces.

Angel Claw

Spoiler

Show

Angel claw is a creature that resembles skinless arms and shoulders. The overly large “shoulder blades” that give to the “angel” portion of this seru name, each have two deep purple eyes that scan about seeking a suitable host. When attached to a host, it effectively hugs the host with its tri-clawed feet reaching out beyond the hands of its mount.

The angel claws are an elven creation from a war lost to time. When the battleground that saw their use was swallowed into the earth, most angel claws found hibernation to be the best option to wait out the centuries. Whether they were found and brought back, or found their own way back to the surface is unknown. They have since found pleasant cohabitation with elves to help them climb trees, as tools of war, or as defenders of certain locations. A hive of angel claws close their “arms” inward and cling to the base of a tree, giving the tree a white bone-like visage. When alerted, the white tree comes alive with hundreds of purple specks as the angel claws assess the threat.

Breed leeches are an extraordinary turn in seru evolution. Instilled in each leech is an infection that changes a regular pregnancy if allowed to run its course. The resulting child is born a seru half-blood. The breed leech attaches with its tri-mandibled mouth, usually on the back of the upper arm, the shoulder, or the lower leg. As such, it is not usually visible on creatures that wear clothing.

Carapace Shell

Moving with a clattering sound, the misshapen crab-like creature ambles about seeking sustenance or a host. Much larger than the restless armor, this evolutionary throwback seems to precede the restless armor. Stronger, larger, but not intelligent, the carapace shell is sometimes thought to be a better seru than the restless armor.

The host gains a +5 armor bonus. A carapace shell has a -4 armor check penalty, a maximum Dexterity bonus of +4, and an arcane spell failure chance of 15%. The host is treated as wearing medium armor. There is no penalty for sleeping in the seru. It can be enchanted as regular armor but costs 1.5 times the normal price.

Carapace shells are in every way physically like a restless armor except in mass, color of its eye, and natural armor shape. The shell only has upwards of 30 or so chitinous plates versus the restless armor’s roughly 300; the shell’s plates are larger and thicker however. The shell has a blue eye and is covered by a single plate, as opposed to the series of smaller plates covering the restless armor’s red eye.

Cladonil have no natural forms of attack, and as such seek out hosts to bear them and provide protection. When in their monthly mating season, several cladonil wrap around each other and within days a clutch of 3-5 eggs are formed.

Special Abilities

Solar Focus (Sp): When threatened during a clear and sunny day, a group of at least 10 of these tiny flyers will focus the rays of the sun into a painful beam in efforts to drive away attackers. As a full-round action, at least ten clockwork heralds arrange in a fractal formation and deal 10 points of fire damage to a target within 50 feet (DC 10 Reflex save for half damage). Each additional herald in the array adds one point of fire damage and +1 to the save DC. No herald may use this ability more than once within 10 rounds.

Host Benefits

Eagles Senses (Ex): The clockwork herald enhances hearing and sight. The herald provides a circumstance bonus of +2 on Perception checks to the host.

Instant Recognition (Su): While wearing the herald, the host can record a person’s defining factors (i.e. features, voice, body build/stance, etc.) and add it to the herald’s memory. Memorizing the person has the following requirements; the host must be within 30 feet of the person, the herald must be able to see and hear the person, the host and person must not be attacking or threatened. There are a total of 10 personnel slots available in the herald’s memory. A 10 word note can be added with each person. Each person viewed through the herald that is within its memory glows a bright orange. Bluffing the herald requires a DC 35 Disguise check.

Message Receiver (Su): This function allows the message spell to be received by the Herald from any distance, unless the sender and host aren't on the same plane or one is in an extra-dimensional space. The message is only heard by the host, then can be recorded and saved by the herald at the request of the host; a total of 5 messages can be stored at any time. The Herald can play any of the stored messages at the request of the host. The sender must add themselves to the clockwork herald's memory to use this function.

This abnormally large slug pulses various colors randomly and have human-like teeth sprouting from their back. These teeth are placed over the eye socket of a host and sink deep into the bone to cover the eye; it then sends hair sized filaments into the host’s brain.

Special Abilities

Detect Aberrations (Su): The detection worm is always considered to have detect aberrations spell active. It functions as normal and at 1st caster level.

Detection Net (Su): Detection worms can sense the results of other detection worms’ detect aberrations ability as long as the effect overlaps by 5 feet or more. For example, the first worm has a detection range of thirty feet. If a second worm’s field overlaps the first worm’s field by 5 feet, they can both sense each other’s entire field. If a third worm’s field enters the field of the second worm opposite from the first worm, all three worms can sense each other’s fields. For each detection worm that is a part of the detecting net, the caster level of the effect is increased by 1 up to a maximum of 20th caster level. More worms can be a part of the net, but the caster level never increases beyond 20. This ability is suppressed when the worm is attached to a host.

Host Benefits

Special Abilities

Crush (Ex): If a dockman is holding a small sized or smaller object, it can, as a full-round action, deal 4d8 plus two times his Strength modifier in damage to the object and ignores hardness 19 or less.

Muscled Jump (Ex): The dockman covers abnormal distance when leaping. The dockman is always considered to have a running start and distance traveled horizontally is calculated on a 2:1 scale (for example, if the jump check result was 32 the dockman travels 64 feet forward). Distance travelled vertically is always calculated on a 1:1 scale. His travel distance from jumping is not limited by his base move speed. He also gains an untyped +10 bonus to Acrobatics checks for jumping and uses his Strength modifier instead of Dexterity when using Acrobatics to jump.

Photosynthetic (Ex): The dockman obtains all its nutrients from the sun and water. Four hours a day in direct or part sunlight, and 10 gallons of fresh or salt water each week give the dockman all it needs for sustenance when not attached to a host.

Strong Back (Su): A dockman can, once per day, increase its own or it’s host’s Strength score by +10. This ability lasts until the start of a round after the dockman moves more than ten feet.

Host Benefits

Massive Frame: A creature with an attached dockman gains a +4 natural armor bonus, becomes a large sized creature, and gains the use of the dockman’s Strength score or a +8 bonus to Strength, whichever is higher. The host’s base movement speed drops to 10 feet and is treated as though he or she were wearing heavy armor with an armor check penalty of -10 for the purposes of movement (except when using the Jump or Climb skill). The host may make use of the dockman’s crush, strong back, and muscled jump abilities. A host wearing a dockman cannot use weapons or make attacks.

Dockmen aren't men, and unlike most plant creatures, are hermaphroditic. They are workhorse seru, and are very simple minded creatures, almost incapable of even forming coherent thoughts to communicate to their hosts. From the center of its chest protrudes several hundred tiny pink polyps that turn bright red when it senses danger. When not attached to a host it simply becomes limp (normally falling from the trees that it calls home) in hopes danger will simply pass by. When attached to a host, it can be compelled to continue to move but will never make attacks.
These seru bud sapling dockmen from the polyps on their chest once every 10 years in group of 20 or thirty. After six months, the now human head sized saplings fall from the “parent” dockman and must survive on their own. Normally the “parent” dockman is in its treetop habitat when the saplings fall. Most saplings that don’t attached to a branch fall prey to natural predators or are gathered up to be sold.

Host Benefits

A creature with an attached eldritch claw gains access to the seru's sudden empower spell-like ability feat, which can be used normally as if the host had the feat. In addition, the host can use the eldritch blast of the eldritch claw, but the damage it deals is only 1d6. The host also gains a claw attack that deal damage as a crawling gauntlet plus 1 point of untyped arcane based damage. Additionally, the host can channel a touch or ray spell into the eldritch blast, a target hit by the eldritch blast is also affected by the channeled spell.
If the host already has an eldritch blast, he may channel it through the eldritch claw as a free action when making claw attacks. When channeled in this manner, the effective eldritch blast of the wielder is 1d6+1 higher.

Eldritch claws are rare, magical seru that bond with spellcasters giving them greater versatility with their spells. They tend to keep to themselves, but are often pressed into service for sorcerers or wizards, and are used as a method to pass around the secrets of manipulating and filtering magic, and as an unlimited use offensive tool. Eldritch claws attach themselves to the hand and forearm of their host.

Flame Glove

A small clearing in the grasslands sometimes has what appears to be 10-20 severed and gruesome looking forearms just lying about. When a hapless animal stumbles upon them, they begin pulsing with an inner flame and come alive to swarm on the victim, tearing it and then searing the flesh before consuming it. The aftermath of a flame glove feeding looks like a small massacre.

Flame Gout (Su): Once every other round, a flame glove can make a ranged touch attack that deals 2d4 points of fire damage to any one target within 30 ft. The flame glove loses this ability when attached to a host.

Host Benefits

The host gains the use of the flame glove as a natural claw attack that deals 1d6 points of damage plus 1 point of fire damage. Attacks made with the claw are considered magic for the purposes of overcoming damage reduction. Additionally, once every 1d4 rounds, the host may make a ranged touch attack that deals 2d4 points of fire damage to any one target within 30 ft.

Special Abilities

Flesh Burrow (Ex): A heart scarab may burrow through the bodies of creatures which are either dead, helpless, or willing at a speed in inches equal to its burrow speed. Burrowing through flesh cause no damage to the creature's body due to the healing mucus that the beetle secretes.

Electric Damage (Ex): When it bites, or is hit by a melee attack, the heart scarab can send a jolt of electricity through the subject dealing 1d6 damage.

Host Benefits

Channel Electricity (Ex): The heart scarab's ability to send a current through the body of its host allows it to channel electricity it into the flesh of the host. When the host wields a metal weapon or uses a natural attack, he deals an extra 1d4 electric damage. This deals 1 point of non-lethal damage to the host each use. The host may communicate to the heart scarab as an immediate action to activate or deactivate this ability.

Jump-start (Ex): As a free action once per round when the host dies, the heart scarab may use its electric effect to keep the host barely alive. This effect leaves the host stabilized at -9 hit points.

Reverse Flesh Heal (Su): Heart scarabs can move freely through the host when the host is relaxed (helpless or unconscious) by detaching its legs from its body. The scarab maintains connection to the host by extremely long tendrils of nerves in its legs. At that time the heart scarab can relocate pieces of the host's body to seal and heal certain wounds. As a full-round action, the heart scarab heals 1d8+2 damage to the host by dealing 1 point of Constitution damage to the host. This ability cannot be used if it would reduce the host's Constitution score to zero. If the host takes damage during the round in which the heart scarab is healing it, there is a 5% chance that the scarab is in the damaged area and is slain.

The heart scarab is normally sought after instead of randomly found.

The heart scarab, normally being a good creature, is also very willing to take a host. It is normally unseen; this is because the heart scarab attaches by sinking its six legs into the heart of its host.

The absorbed creature may make a DC 15 Strength check every round to attempt to escape. When the creature must make its first Constitution check to avoid drowning, it instead instantly drowns as the hulk skin sends part of its mass into the creatures body.

Speedy Climb (Ex): The hulk skin can make a run action even when climbing.

Host Benefits

Enhanced Body: The host gains a +6 bonus to strength, +4 to constitution, and +4 to dexterity.

Powerful Build: Physical stature increases, letting the host function in many ways as though she were one size category larger. Whenever a host is subject to a size modifier or special size modifier for an opposed check, she is treated as one size larger if doing so is advantageous to her. Also considered one size larger when determining whether a creature's special attacks based on size can affect her, and for carrying capacity. The host can use weapons designed for a creature one size larger without penalty. However, space and reach remain those of a creature of the host's actual size. Benefits of this stack with the effects of powers, abilities, and spells that change the subject's size category.

Natural Attacks: The host gains a bite attack for 1d10 damage, and two claw attacks for 2d4 damage each. Also, all unarmed strikes deal damage as a large monk of 5th level. The host has access to the skin's improved grapple feat while attached. A side effect of the savage nature of the hulk skin is that the host gets a -4 on all attacks made with manufactured weapons. The overwhelming desire to rend and tear with your bare hands impairs training and logical thought. Damage given assumes medium sized host and take into account powerful build.

Uncanny Dodge: Host retains dexterity bonus to AC regardless of being caught flat-footed or being struck by an invisible attacker. Dexterity bonus to AC is still lost if immobilized.

Superior Movement: The host gains a 20 foot climb speed. Gains the benefits of the Run feat, and height is no longer a limiting factor in a jump.

Thick Skin: Grants a +2 bonus to the host's natural armor. If the host does not have natural armor, treat their natural armor score as 0.

Hungry(Ex): The host must consume three times the normal amount of food and water every day while bonded. Any organic matter can be consumed for this purpose. The flesh of intelligent victims is particularly enjoyed and will pacify the seru, negating 1 point of mental ability damage for the following day. Up to 3 intelligent creatures may be eaten each day to reduce ability damage up to 3 points.

A jade sludge is an ooze that has undergone certain magical changes after being nearly starved.

Special Abilities

Corrupting Touch (Ex): If a shadow sibling makes a successful touch attack, it disrupts a foe with its ability to bond flesh, dealing 1d6 points of damage.

Host Benefits

A shadow sibling settles around its host like a second skin, granting the host protection from some physical attacks. While wearing a shadow sibling, a creature can gain 50% concealment against any single attack as an immediate action. You must decide whether to use this benefit before you know the result of the attack roll.
The creature can use this ability a number of times per day equal to its Constitution modifier (minimum once per day). This concealment has no effect against weapons or effects that ignore the miss chance of incorporeal creatures (such as force effects or weapons enhanced with the ghost touch special ability). Using this ability does not provoke attacks of opportunity.
Moreover, a shadow sibling partly blocks ambient light, giving the host creature and its equipment a shadowy appearance even in full daylight. This effect grants the host

Host Benefits

The Skewer Ant wraps its limbs around the host's wrist. The Skewer Ant's body segments become completely rigid and acts as a buckler. The buckler form of the Skewer Ant gives a +1 Shield bonus to AC. The buckler form has no armor check penalty or arcane spell failure. You need not be proficient with shields to gain the +1 shield bonus and this doesn't stack with other bonuses from shields.

Acid Skewer (Ex): As a move action (at the mental command of the host) the skewer ant can open its mandibles wide and a green goo oozes from its open mouth. It quickly hardens into a sharp icicle-like rod it can be used as a punching dagger. The punching dagger form of the skewer ant deals 1d4 pierce damage as a punching dagger of a medium size and an additional 1d4 acid damage. The acid skewer is treated as a punching dagger for proficiency and feats. As a free action the acid skewer can be removed from the skewer ant the acid skewer turns back into ooze and evaporates into nothing.

Constitution damage taken in this manner can be mitigated, but not as normal. If the host has immunity to the Constitution damage, reduction of the Constitution damage, or some other mitigating factor, the damage is in fact dealt but the mitigating factor takes into effect two rounds later as if he had just taken it.
The host also gains a claw attack that deal damage as a crawling gauntlet plus 1 point of untyped arcane based magic damage. If the host casts a spell that the spellfilter claw has access to normally or any touch spell, the spell is cast at a +1 caster level.

Additionally, the host adds the spellknight’s spell-like abilities to his spells known list and may use the spellknight’s spell-like abilities. When using these spell-like abilities, use the seru’s caster level or the host’s, whichever is higher.

Host Benefits

A creature with an attached spellwurm gains increased spellcasting ability. Creatures that cast arcane spells spontaneously (such as sorcerers, bards, or warmages) gain of the spellwurm’s spells as additional spells known, even if these spells are not normally on the spell list for their class. Wizards and other arcane spellcasters who prepare their spells ahead of time can prepare the spellwurm's spells without the aid of a spellbook, as if they had previously known all those spell and taken the Spell Mastery feat for each.

Spellwurms are very popular among spellcaster’s for obvious reasons. They become even more valuable to a spellcaster who has lost a limb used for his art. The spellwurm can attach anywhere, but the primary location is under an arm or where an arm used to be. In either case, the spellwurm cannot perform the normal functions of an arm, just cast spells.

Special Abilities

Burst (Ps): As a swift action, the swiftjerker can gain a move action. This ability is suppressed when attached to a host.

Detect Psionics (Ps): A swiftjerker can continuously sense psionic creatures as the detect psionics power. This ability is suppressed when attached to a host.

Paralyzing Shock (Ex): The neural energy coursing through the swiftjerkers deals 1d6 electricity damage to any living creature who end their round in the jerker's space. Those whom take damage must succeed on a DC 11 fortitude save or fall into paralyzing spasms for 1 round. Once attached it loses this ability, instead using this energy to enhance the host. This ability is suppressed when attached to a host.

Skills: Swiftjerker's have a +4 racial bonus on Climb and Stealth checks. They have a +8 racial bonus on Acrobatics checks. They use their Dexterity modifier instead of their Strength modifier for Climb. A swiftjerker can always choose to take 10 on Climb checks, even if rushed or threatened.

Host Benefits

The host of a swiftjerker find themselves reacting so quickly to their surroundings that they have the sensation of the entire world slowing around them. The new tendril connection produces reaction time far superior to the original creature's, forming a sort of neural shortcut. This provides the host with a +2 enhancement bonus to reflex saves and a +6 enhancement bonus to initiative checks.
Creatures with a power point reserve also gain Evasion, and are drained of 1 power point for each use.
Upon a roll of 1 when these enhancements would be used, the signals of the host and seru conflict violently. This surge of random impulses stuns the host for 1 round.
The host also can use the burst ability. Each time the host uses the burst ability, the swiftjerkers drain 1 power point from the host. If the host is a non-psionic creature or no longer has power points to drain, it takes 1d4 points of non-lethal damage from the exertion.

The tendrils of a swiftjerker twist and meld with dozens of other jerkers like individual parts of a single creature. When attached to a psionic creature they flicker with a vague white fire within. The swiftjerker completely envelopes the body of a helpless creature, attaching to key muscle groupings and along the spinal column. They then thread their tendrils throughout their host's body and meld with those of other jerkers to form an enhancement to the neural-muscular system. These tendrils then feed into the jerker who attaches to the base of its opponent's skull. It, in turn, melds with specific portions of the brain itself.
Swiftjerkers are phenomenally swift, as they don't act, but react with explosive bursts of sudden, inexplicable speed. Despite this they are weak and their mode of locomotion painfully slow so that they often fall prey to predators. To increase their chances of survival they thus meld with larger, more powerful creatures and enhance their ability to react to their surroundings, making it more likely for both host and seru to survive.
Swiftjerkers often hide within cracks or above ledges, waiting for a potential host to pass through. If they are in an area small enough they link together to form a web-like obstruction. Creatures passing through are immediately shocked, giving the serus a chance to join with the beast.

Host Benefits

The host cannot use a weapon or shield in the hand holding the whip, although he can make an unarmed strike using that hand. Because the weapon is attached to the arm of the host, it cannot be the target of a disarm attempt.
A tentacle whip has a reach of 15 feet and can attack adjacent foes without penalty. A tentacle whip deals lethal damage and injects poison into the target's bloodstream with a successful hit.
A tentacle whip can make a single attack per round using its own attack bonus and statistics. Alternatively, the host can use the whip as a weapon. In this case the user's attack bonus and Strength are used; the whip has a number of additional benefits, described below.
While it has no enhancement bonus, a tentacle whip (whether used as a weapon or left to attack independently) is considered a magic weapon for purposes of overcoming damage reduction.

Channel Touch (Ex): A tentacle whip can be used to deliver a touch attack—either a natural power of the bearer or a held magical charge.

Improved Attack (Ex): A tentacle whip is bound to the nervous system of its host; when it is used as a weapon, it can guide the hand of its wielder and provides the following additional benefits.
—The wielder takes no penalty for using the tentacle whip in an offhand (although he does take all other relevant penalties if attacking with two weapons).
—The wielder gains a +1 bonus on all attack rolls made using the whip.
—The wielder gains a +4 bonus on CMB checks made to disarm and trip an opponent. The wielder does not provoke attacks of opportunity when attempting to trip or disarm, and he cannot be tripped or disarmed if he fails his attempt.

Host Benefits

A creature with a tongueworm gains a natural sting attack. This sting attack replaces the creature's bite attack, if it has one. With a successful hit, the tongueworm injects a paralytic poison (see above). An attached tongueworm has a 5-foot reach and can be used to make grapple attempts and disarm attempts.

They also seek to resolve a larger number of conflicts through nonviolent means. The tongueworm lies flat over the host's tongue and tucks its poison barb under its own body when not deployed. It extends its whip like tail down the host's throat and into the host's stomach.

Host Benefits

A throwing scarab generates small shards of hard crystalline carapace. The host can grasp one of these shards as a free action and throw it as a normal ranged attack. The shard has a range increment of 20 feet, and the host is always proficient with it. When thrown in this fashion, the shard is treated as a magic weapon for the purpose of overcoming damage reduction. On a successful hit, the shard deals 1d6 points of slashing damage (critical 19–20/x2) and then dissolves in its target, dealing an additional 1d6 points of acid damage.
At the beginning of the host’s next action, the throwing scarab secretes another shard, allowing the host to throw one shard each round. Shards do not last for more than 1 round once detached from the seru. If a shard is not used as a weapon within 1 round after being pulled from the seru, it dissolves harmlessly.
While attached to the host, a throwing scarab does not make any attacks of its own.

When in the defensive shell, the kemaro reduces his effective Dexterity score to 1 (gaining an additional -4 penalty to Dexterity based skill checks, AC, and Reflex saving throws) but gains +4 additional natural armor. While in this state the kemaro cannot move unless moved forcibly, cannot make Reflex saves, nor can it change its field of vision. The kemaro also grows jagged bone spikes from its outer casing that deal 2d6 +10 damage to creature who hit the kemaro with a melee or natural attack. The kemaro may remain in this state indefinitely but may only enter it times per day equal to its Constitution modifier (minimum 1). Ending this state is a move action. This ability is suppressed when the kemaro is attached to a host.

Host Benefits

The host gains a +6 armor bonus. A kemaro has a -5 armor check penalty, a maximum Dexterity bonus of +2, and an arcane spell failure chance of 20%. The host is treated as wearing heavy armor. There is no penalty for sleeping in the seru. It can be enchanted as regular armor but costs 1.5 times the normal price.

The host also gains the use of the defensive shell ability. It can only be used a number of times per day equal to the host’s Constitution modifier (minimum 1).

This seru may be mistaken for a very odd statue when encountered. However, it quickly changes to a curious canine that looks to eat and taste anything it can get its maw into. The kemaro attaches by splitting itself down the center of its torso, legs, arms, and jaw. It then engulfs the host, resealing its body around the encompassed creature. The kemaro can leave certain spots slightly open to accommodate other seru on the host.

Dash (Ex): The barra can move 5 times its move speed as a move action. This is not a run action. When using the run action the barra moves at 7 times its move speed. This ability is suppressed when attached to a host.

Host Benefits

A creature with an attached barra gains a +10 bonus to move speed.

Dash (Ex): As a swift action a number of times per day equal to the host’s Constitution modifier (minimum 1), the barra may send a surge of fluids through its host and increase its speed. For one round after activating this ability, the host may move 5 times its move speed as a move action.

Special Abilities

Tail Fire (Su): As a standard action, a gimard may launch a small ball of fire from its claw tail to any target within 60 feet that deals 2d4 damage. The target may make a Reflex save (DC 12) for half damage. This ability is suppressed when attached to a host.

Host Benefits

The host cannot use a weapon or shield in the hand holding the gimard, although he can make an unarmed strike using that hand. Because the weapon is attached to the hand of the host, it cannot be the target of a disarm attempt.
A gimard has a reach of 10 feet and can attack adjacent foes without penalty. A gimard deals lethal damage and burns the target for 1d4 fire damage (in addition to the base 1d4 slashing damage) with a successful hit. The gimmard counts as a dagger or a whip for the purposes of weapon related rules.
Unlike a tentacle whip, a gimard cannot make a single attack per round using its own attack bonus and statistics. The host primarily uses the whip as a weapon. In this case the user's attack bonus and Strength are used; the whip has a number of additional benefits, described below.
While it has no enhancement bonus, a gimard is considered a magic weapon for purposes of overcoming damage reduction.

Channel Touch (Ex): A tentacle whip can be used to deliver a touch attack—either a natural power of the bearer or a held magical charge.

Improved Attack (Ex): A gimard is bound to the nervous system of its host; when it is used as a weapon, it can guide the hand of its wielder and provides the following additional benefits.
—The wielder takes no penalty for using the gimard in an offhand (although he does take all other relevant penalties if attacking with two weapons).
—The wielder gains a +1 bonus on all attack rolls made using the gimard.

The gimard prefers to simply hang wrapped around a stalactite until food comes along. They rarely, if ever, come to the surface unless brought by a host. The gimard attaches by opening its beak wide to place the hand of the host into its mouth. The beak closes tight around the hand and sinks in tendrils to connect with the host.

Special Abilities

Slay Seru (Su): If a jedo seru deals damage to a seru, it can attempt to instantly slay the damaged seru. The damaged seru must make a Will save (DC 10) or die instantly. This ability is suppressed when a jedo is attached to a host.

Host Benefits

A creature with an attached jedo gains the use of the slay seru power against any rebelling seru. If a conflict arises between a seru and its host and the host fails the Ego Will save, the host may invoke this power on the rebelling seru. A jedo is immune to its own slay seru power.

Special Abilities

Water Jet (Ex): As a move action a mul may exude a stream of water from its gullet that propels it in reverse 50 feet. When attached to a host this ability is suppressed.

Host Benefits

A creature with an attached mul can mentally command the mul to use its water jet ability as a free action. The mul still uses a move action to perform the ability. When in water, the host is propelled in any direction five feet for every mul (up to a maximum of 50 feet with 10 mul) attached and has unlimited uses. When on land, the host is propelled laterally five feet for every 2 mul (up to a maximum of 25 feet with 10 mul) attached and costs 1 Constitution for every 5 foot propelled as the mul drain the host for the required water for the move.
Note: For statistical purposes, each use of a mul’s water jet ability generates 5 gallons of water

Craft Seru [Item Creation]
Prerequisite: Either Craft Magic Arms and Armor or Craft Wondrous Items
Benefit: You have the ability to grow internal items that are considered seru. Growing a seru requires a live, helpless aberration. See the seru subtype rules for more details.
Special: Seru Half-bloods can use themselves as the base aberration to grow symbionts. Seru Half-bloods use their character level as the caster level for creating symbionts and can ignore the prerequisites if they have five or more hit dice.

It's really neat, and I like it. I may also borrow it for my games.

Anyone have comments on balance or discrepancies for the "as treasure" table?

[Milo v3]

Anyone have comments on balance or discrepancies for the "as treasure" table?

Well first off, you might want to make it more clear that the Hulk Skin is the Artifact. It says * at the bottom, but it doesn't have it in the table.

As for pricing, I'll look at the Breed Leech as if it was a normal magic item.
It should be worth around 5600 gp (2000 for +1 Fortitude, 800 for Health, x2 for no-slot). Now to find the proper price we'd need to figure out how much the whole living gear and ability damage are worth.

Your pricing puts it on being worth /2.8 which places the Breed Leech on exactly 2000 gp.

So, to make sure the pricing of the rest is fair you could just do pricing as a magic item, then divide the cost by 2.8.

[Deviston]

The core symbiont pricing are all from the Magic of Eberron table. Copy pasta, that being said maybe THEY didn't even put more thought into it than "here are some numbers".

I believe the reduced price (for example the breed leech) is due to Ego saves and what not. IF you fail one, the symbiont controls you for X time.

[Deviston]

Added 14 MORE symbionts (aka seru). All themed from the game Legend of Legaia either vaguely or very closely. One can NEVER have enough symbionts!

BTW, feel free to PEACH at your heart's content. I would welcome the critiquing.

EDIT: It has been pointed out to me that there are certain formatting/grammatical errors. Please annotate which symbionts these errors are in so I may fix them.
