View Full Version : Spotting Invisibility

If a character spots an invisible creature by way of a high spot check, do attacks against the invisible creature take a 50% miss chance for concealment?

Also, can a creature use the hide skill in conjunction with invisibility to sneak up to a spotter in the open? If so, does the spotter's DC to spot them equal the hide check + 20 for invisibility?

1. Yes. A Spot check of 20=< lets use be aware of an invisible creature, but you can't actually see it. Thus, the miss chance still applies.

2. By the rules it might make sense. I guess it works. If the invisible person is trying extra careful to be unseen, then maybe the spotter might need to look extra carefully.

an invisible creature gains a +20 to its hide check. Also because they are invisible, unless a creature can see invisibility, they are considered concealed thus they can sneak in the open to that person.

Can't you just see them with Arcane Sight?

Arcane sight is like a quickened detect magic, in that you get all the information with out concentration. So a DC 18 Spellcraft check will tell you the location of the invisible person's aura, and how strong it is. In this case you will know that there is a faint aura in the invisible man's location, but you will still be unable to acutally "See" him. And a lvl 3 or higher spell in the area can disguise his aura. Easiest way is See Invisibility.

Assuming they're using a spell or a magic item, you can see the aura, yeah. No clue what sort of concealment (if any) they've got then...

They've got 100% concealment, which means a 50% chance of missing if you attack the square. An aura isn't like a magical silhouette. By the rules, you get the location of the aura, which means just the 5' square(s) the aura occupies. Seeing an aura doesn't let you "clearly see" the person or thing generating the aura, so you don't have enough information to target them.

True Seeing works wonders in this department...

I thought 3.5 changed that so you don't get a + to you hide check.
Invisibility
Illusion (Glamer)
Level: Brd 2, Sor/Wiz 2, Trickery 2
Components: V, S, M/DF
Casting Time: 1 standard action
Range: Personal or touch
Target: You or a creature or object weighing no more than 100 lb./level
Duration: 1 min./level (D)
Saving Throw: Will negates (harmless) or Will negates (harmless, object)
Spell Resistance: Yes (harmless) or Yes (harmless, object)

The creature or object touched becomes invisible, vanishing from sight, even from darkvision. If the recipient is a creature carrying gear, that vanishes, too. If you cast the spell on someone else, neither you nor your allies can see the subject, unless you can normally see invisible things or you employ magic to do so.

Items dropped or put down by an invisible creature become visible; items picked up disappear if tucked into the clothing or pouches worn by the creature. Light, however, never becomes invisible, although a source of light can become so (thus, the effect is that of a light with no visible source). Any part of an item that the subject carries but that extends more than 10 feet from it becomes visible.

Of course, the subject is not magically silenced, and certain other conditions can render the recipient detectable (such as stepping in a puddle). The spell ends if the subject attacks any creature. For purposes of this spell, an attack includes any spell targeting a foe or whose area or effect includes a foe. (Exactly who is a foe depends on the invisible character’s perceptions.) Actions directed at unattended objects do not break the spell. Causing harm indirectly is not an attack. Thus, an invisible being can open doors, talk, eat, climb stairs, summon monsters and have them attack, cut the ropes holding a rope bridge while enemies are on the bridge, remotely trigger traps, open a portcullis to release attack dogs, and so forth. If the subject attacks directly, however, it immediately becomes visible along with all its gear. Spells such as bless that specifically affect allies but not foes are not attacks for this purpose, even when they include foes in their area.

Invisibility can be made permanent (on objects only) with a permanency spell.

Snagged from the srd...can't find a 3.0 srd to confirm it though :smallfrown:

There are a bunch of ways to deal with Invisibility. The easiest way is to just buy one of the many items that grant See Invisibility or something similar. I think there's a really cheap one in the Item Compendium. Or you can just buy a few potions - unless you have a sadistic DM, Invisible enemies won't be every game day.

Another method is to make a Listen check (http://www.dandwiki.com/wiki/SRD:Invisibility) to locate your enemy's square (usually DC of 0 if your enemy is in combat and not attempting to Move Silently), and then take the Pierce Magical Concealment feat (or Blind Fighting, if you're a caster of some sort).

Every character I've ever played since 1st ed also carries a large bag of chalk. Throw some crushed chalk in the air around you, and you can see the footsteps of anyone walking up to you. Not RAW, but most DMs allow it.

Looks like it says in the SRD that you have to beat the DC by twenty to pinpoint an invisible character, so in battle, no more than ten feet away, that's DC 0 + 20, assuming the target isn't running around. Hard, but possible for just about anyone.

This is straight from the SRD too:

The ability to move about unseen is not foolproof. While they can’t be seen, invisible creatures can be heard, smelled, or felt.

Invisibility makes a creature undetectable by vision, including darkvision.

Invisibility does not, by itself, make a creature immune to critical hits, but it does make the creature immune to extra damage from being a ranger’s favored enemy and from sneak attacks.

A creature can generally notice the presence of an active invisible creature within 30 feet with a DC 20 Spot check. The observer gains a hunch that “something’s there” but can’t see it or target it accurately with an attack. A creature who is holding still is very hard to notice (DC 30). An inanimate object, an unliving creature holding still, or a completely immobile creature is even harder to spot (DC 40). It’s practically impossible (+20 DC) to pinpoint an invisible creature’s location with a Spot check, and even if a character succeeds on such a check, the invisible creature still benefits from total concealment (50% miss chance).

A creature can use hearing to find an invisible creature. A character can make a Listen check for this purpose as a free action each round. A Listen check result at least equal to the invisible creature’s Move Silently check result reveals its presence. (A creature with no ranks in Move Silently makes a Move Silently check as a Dexterity check to which an armor check penalty applies.) A successful check lets a character hear an invisible creature “over there somewhere.” It’s practically impossible to pinpoint the location of an invisible creature. A Listen check that beats the DC by 20 pinpoints the invisible creature’s location.

In our campaigns being invisible isnt all that great if the players have the brains and spot checks to outthink the creatures

Or you can just buy a few potions - unless you have a sadistic DM, Invisible enemies won't be every game day.The problem with this (and with the chalk dust, and with Glitterdust or Dust of Appearing) is that you first have to have some indication that the creature is there.

Player: "Do I see anything?"
DM: "No."
Player: "OK, I drink a potion of See Invisibility. Do I see it now?"
DM: "No."
Player: "All right, I cast Glitterdust, and then throw a packet of Dust of Appearing."
DM: "You still don't see anything."
Player: "How is that possible? Dust of Appearing reveals everything"
DM: "Maybe there's nothing there?"

Of course, it's still useful if you're getting Sneak Attacked by someone with Greater Invisibility, or if the invisible creature is otherwise calling attention to itself. But invisible creatures don't always call attention to themselves.

What section is that in the srd?

I checked under statuses and just got

Invisible
Visually undetectable. An invisible creature gains a +2 bonus on attack rolls against sighted opponents, and ignores its opponents’ Dexterity bonuses to AC (if any). (See Invisibility, under Special Abilities.)

Edit:Ah...its under epic skills...figures... :smallannoyed:

Gyabou! The most reliable way to see an invisible creature or character is to take ten levels of scout or another class that grants blindsight (is there another?) or take the epic feat Blindsight which is only available to WIS 19+ people (so, Monks). This keeps sneaky invisible peeps from sneak attacking.

Eh, if you're going to assume that you have access to whatever books you need to get blindsense or similar, then you might as well assume that the enemy sneaks have access to Lords of Madness, and took Darkstalker.
