List of my 3.5 Homebrew: Class Variants, Feats, and Creatures

[Adamantrue]

This is a consolidated collection of much of my homebrew, over the years. I’m putting it all in one place, cleaning up the formatting & typos & what-not. I hope to continue adding and updating this in the future.

Currently included are some Class Variants, Homebrew Feats, and Creatures.

I tend to focus on the lower-tier stuff, mostly for two reasons. Firstly, they tend to be the things most in need of the help. But secondly, and most importantly...it's the stuff I enjoy playing, and a tweak here and there makes it more enjoyable.

Obviously, it's all still open to be evaluated & critiqued, but I’m pretty comfortable with the things I’ll list here.

Class Variants

Knight Variants

Knight Specializations
A common Knight fix is to give them access to the Fighter Feat list, but I think that steps on a Fighter's toes a little too much. I mean, a Fighter 9 and a Knight 5/Fighter 4 would have the same number & choices of Feats, but the Knight comes out ahead with more Hit Points & some other Class Feature goodies.

Instead, I offer additional flavors, to add variety. They are keyed to Ability Score prerequisites, to distinguish them from the "Generic Knight" from PH2. Credit to Atewi at Myth Weavers for the names of these variants.

Racial Substitution Levels: Dwarven Knight
A dwarven knight is known for his endurance and resolve. Enemies and allies notice this relentlessness and fortitude, which defines his presence on the battlefield.
Hit Dice: d12
Requirements
To take a dwarven knight substitution level, a character must be a dwarf about to take her 1st, 4th, or 9th level of knight.
Class Skills:
Dwarven knight substitution levels have the class skills of the standard knight class.
Skill Points at Each Level: 2 + Int modifier (or four times this number as a beginning character).

Class Features
All of the following are features of the dwarf knight’s racial substitution levels.
Dwarven Warcry: As Knight's Challenge, except a dwarven knight uses his Constitution modifier instead of his Charisma modifier for all abilities related to Knight's Challenge.
This ability replaces the Knight’s Challenge ability gained by a standard knight at 1st level.
Dwarven Challenge (Ex): As Fighting Challenge, except a dwarven knight applies this morale bonus to damage rolls, armor class, and Fortitude saves against the target of this ability.
This ability replaces the Fighting Challenge ability gained by a standard knight at 1st level.

This ability replaces the Armor Mastery ability gained by a standard knight at 4th level.
Dwarven Armor Master (Ex): At 9th level, a dwarven knight ignores the speed reduction imposed by any exotic armor that affects even dwarves (such as mountain plate). You must have proficiency with the armor in order to gain this benefit.
This ability replaces the Armor Mastery ability gained by a standard knight at 9th level.

Feats

Art of the Draw [Tactical]
Your draw and strike is one fluid, deadly move.
Prerequisites: Base attack bonus +8, Intimidate 10 ranks, Exotic Weapon Proficiency (Bastard Sword), Improved Initiative, Quick Draw.
Benefit: This feat allows the use of three tactical maneuvers, each of which requires the use of a katana (masterwork bastard sword).
Frightful Kiai: Your focus and confidence is inherently unnerving, and a single action can push an opponent over the edge. To use this maneuver, you must draw your katana and use it to make a successful melee attack in the same round. If you do, you may attempt to demoralize that opponent as a move action before the end of the round.
Wake the Sleeping Sword: Your draw and strike with the katana is one swift and powerful motion. To use this maneuver, you must make a full attack in the same round you draw your katana. If you do, the first attack deals triple normal damage. You may only wield the katana with one hand when making this first strike, and all remaining attacks (if any) are resolved as normal.
Clean the Blade: To use this maneuver, you must have initiated a duel of wills (Tome of Battle p27) during the encounter, and landed the attack that drops the chosen opponent. After that strike, as an immediate action that does not provoke an attack of opportunity, you may sheathe your katana and initiate a new duel of wills against a different opponent. Note that an opponent's initiative is not altered in any way if they choose to submit.
Special: A fighter may select Art of the Draw as one of his bonus feats.
A samurai's Iaijutsu Master ability counts as Quick Draw the purpose of qualifying for this feat. An 8th level samurai may select Art of the Draw as his bonus feat if he gained Improved Initiative at an earlier level.

Centaur Charge [Racial]
Your combination of power and mobility makes your charge attacks devastating.
Prerequisites: Centaur, Dodge, Mobility.
Benefit: When using the charge action, you deal double damage with a melee weapon (or triple damage with a lance).
When using Spring Attack, Bounding Assault, or Rapid Blitz, you may also make any or all of the attacks count as a charge. If you do, you can only make a single attack roll against any one opponent, and you must move a minimum of 10 ft in a straight line before each strike.
Special: A centaur fighter may select Centaur Charge as a bonus feat.

When making a Fighting Challenge, you may spend an additional 2 Knight's Challenges to have it also affect your defenses.
For the duration of your Fighting Challenge, your bonus applies as a dodge bonus to AC in addition to its normal effects against that specific foe. You also gain damage reduction equal to your bonus against that specific foe. This stacks with any existing damage reduction you already possess.
Special: A knight may choose Defensive Challenge as one of his bonus feats.

Expert Maneuvers [General]
Proper defensive postures can lure opponents into more vulnerable positions.
Prerequisites: Base attack bonus +8, Combat Expertise, Expert Strike^NEW, Improved Feint, Improved Trip.

Expert Strike [General]

Special: A fighter may select Expert Strike as one of his bonus feats.

Facing the Many [Valor]
Your presence influences groups as easily as individuals.
Prerequisite: Knight's Challenge.
Benefit: Gain 2 additional daily uses of Knight's Challenge.
When making a Fighting Challenge, you may have your bonuses apply to more than one foe with the same action. For each additional opponent, you must spend 2 additional Knight's Challenges. These additional targets must also meet the requirements of Fighting Challenge.
When making a Call to Battle, you may grant a new save to more than one ally with the same action. For each additional ally, you must spend 2 additional Knight's Challenges.
Special: A knight may choose Facing the Many as one of his bonus feats.

Greater Tenacity [General]
You withstand inhuman levels of punishment without falling.
Prerequisites: Base attack bonus +15, Constitution 17, Improved Toughness, Tenacity^NEW.
Benefit: When using the Tenacity feat, you instead heal yourself up to 25 hit points with each use.
At the beginning of your turn, you may spend two daily uses of the Tenacity feat to remove one of the following conditions: ability damage, blinded, confused, dazed, dazzled, deafened, diseased, exhausted, fatigued, feebleminded, insanity, nauseated, sickened, stunned, or poisoned.
You can only remove one condition each round. No action is required to use this ability, and you may use this ability even if you cannot act normally during your turn.
Special: A fighter may select Greater Tenacity as one of his bonus feats.

Improved Agile Shield Fighter [General]
You have improved your technique when using your shield bash with an unarmed strike.

A fearless demeanor strengthens the resolve in your allies, and the fear in your enemies.

When making a Daunting Challenge, you may spend 2 additional Knight's Challenges to make your opponents frightened, instead of shaken.
When making a Call to Battle, you may spend 2 additional Knight's Challenges to grant your allies a new save against any failed Will save, instead of a failed save against fear.
Special: A knight may choose Radiance of Valor as one of his bonus feats.

Rallying Champion [General]
Your prowess inspires those following your direction, and they in turn motivate your efforts.
Prerequisites: Knight's Challenge class feature, Grant Move Action or Adrenaline Boost class feature.
Benefit: If you have levels in Knight and Marshal, those levels stack for the purposes of determining the bonuses you gain when using Fighting Challenge, and the bonus you grant with your Major Aura.

Special: A knight may choose Rallying Champion as one of his bonus feats.

Tenacity [General]
While others may fall, you endure.

The Battleram

I should note that I am now aware of the WoW Battle Ram, but this idea was brewed up independently, ignorant of its existence until recently. So it probably doesn't reflect that concept, if that's what you are looking for, because it isn't meant to.

Anyways, I wanted to distinguish some of my races/cultures from each other, and one of the first things on my list was to have alternative mundane mounts/beasts of burden for various races. I thought a Ram could be a good choice for my Gnomes & Dwarves, as they generally share similar environments.

Of course, I haven't come across any published versions, so I had to make one. It occurred to me that I could start by downgrading a Bison a size category, and get in the right general ballpark.

SRD Bison, for reference:

Spoiler

Show

Bison
Large Animal
Hit Dice: 5d8+15 (37 hp)
Initiative: +0
Speed: 40 ft. (8 squares)
Armor Class: 13 (-1 size, +4 natural), touch 9, flat-footed 13
Base Attack/Grapple: +3/+13
Attack: Gore +8 melee (1d8+9)
Full Attack: Gore +8 melee (1d8+9)
Space/Reach: 10 ft./5 ft.
Special Attacks: Stampede
Special Qualities: Low-light vision, scent
Saves: Fort +7, Ref +4, Will +1
Abilities: Str 22, Dex 10, Con 16, Int 2, Wis 11, Cha 4
Skills: Listen +7, Spot +5
Feats: Alertness, Endurance
Environment: Temperate plains
Organization: Solitary or herd (6-30)
Challenge Rating: 2
Advancement: 6-7 HD (Large)

Stampede (Ex): A frightened herd of bison flees as a group in a random direction (but always away from the perceived source of danger). They literally run over anything of Large size or smaller that gets in their way, dealing 1d12 points of damage for each five bison in the herd (Reflex DC 18 half). The save DC is Strength-based.

OK, so now a simple downgrade & refluff:

Spoiler

"Ram"
Medium Animal
Hit Dice: 5d8+5 (27 hp)
Initiative: +1
Speed: 40 ft. (8 squares)
Armor Class: 13 (+1 Dex, +2 natural), touch 11, flat-footed 12
Base Attack/Grapple: +3/+5
Attack: Butt +5 melee (1d6+3)
Full Attack: Butt +5 melee (1d6+3)
Space/Reach: 5 ft./5 ft.
Special Attacks: Stampede
Special Qualities: Low-light vision, scent
Saves: Fort +5, Ref +5, Will +1
Abilities: Str 14, Dex 12, Con 12, Int 2, Wis 11, Cha 4
Skills: Listen +7, Spot +5
Feats: Alertness, Endurance
Environment: Temperate hills or mountains
Organization: Solitary or herd (6-30)
Challenge Rating: 2
Advancement: 6-7 HD (Medium)

Stampede (Ex): A frightened herd of rams flees as a group in a random direction (but always away from the perceived source of danger). They literally run over anything of Medium size or smaller that gets in their way, dealing 1d10 points of damage for each five rams in the herd (Reflex DC 14 half). The save DC is Strength-based.

We have something that can work in a pinch, but doesn't really feel like a Ram. And as far as game mechanics go, its a little too tough & hits just a little too hard for CR 1, but is underpowered for CR 2.

The reason I wanted to go with a Ram is for something a little more sure-footed in mountainous terrain, a little more exotic than a horse but not at all alien. Something that would make sense to be domesticated as more of a workhorse for Gnomes & Dwarves.

So, I'm going to start by adding a +4 racial bonus on Balance, Climb, and Jump checks in rocky terrain, and increasing its Strength by +2. Stampede doesn't seem appropriate, so I'll drop that. To compensate, I'm going to focus the Feats more, going with Power Attack & Improved Bull Rush.

So, the final result:

Heavy Ram
Medium Animal
Hit Dice: 4d8+4 (22 hp)
Initiative: +1
Speed: 40 ft. (8 squares)
Armor Class: 13 (+1 Dex, +2 natural), touch 11, flat-footed 12

Feats: Improved Bull Rush, Power Attack
Environment: Temperate hills or mountains
Organization: Solitary or herd (6-30)
Challenge Rating: 2
Advancement: 5-7 HD (Medium)

A ram cannot fight while carrying a rider.

Gnomes may ride rams, but Dwarves and Gnomes generally ride in carts behind a team of rams.

Price (adult): 150 gp

Not exactly happy about the way I worded those last two points, and I'm not sure whether I listed the Skill correctly. But altogether, that looks about right.

But wait, that was just the normal animal. What about the mount?

The Gnomehound

Little details help fill out campaign worlds. Even if it's kinda silly.

Gnomehounds are a specialized breed of dachshunds, somewhat common in gnome communities. They have a slow burrow speed, which does allow gnomes to communicate with them. These are the statistics of a "wartrained" version.
