Invisibility
From NWNWiki
- This article is about the effect; for other uses, see Invisibility (disambiguation).
Invisible attacking creatures get a 50% concealment bonus against enemy attacks and can ignore the dexterity modifier of any opponent unless that opponent has the uncanny dodge feat.
The ability to move about unseen is not foolproof. While they cannot be seen, invisible creatures can be heard.
Invisibility makes a creature undetectable by vision, including darkvision.
Invisible creatures without true seeing or see invisibility will get a +2 to attack rolls even against creatures that can detect them, (unless countered by the target having blind fight).
Those attacking an invisible creature will get a -4 penalty to attack rolls.
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 is 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.
| Invisible creature is . . . | DC |
|---|---|
| ...in combat or speaking | 0 |
| ...moving at half speed | move silently check result |
| ...moving at full speed | move silently check result - 4 |
| ...running or charging | move silently check result - 20 |
| ...some distance away | +1 per 10 feet |
| ...behind an obstacle (door) | +5 |
| ...behind an obstacle (stone wall) | +15 |
Invisible creatures leave tracks. They can be tracked normally. Footprints in sand, mud, or other soft surfaces can give enemies clues to an invisible creature's location.
An invisible creature in the water displaces water, revealing its location. The invisible creature, however, is still hard to see and benefits from concealment.
A creature with the blind fight feat has a better chance to hit an invisible creature. Roll the concealment percent twice, and he misses only if both rolls indicate a miss. (Alternatively, make one 25% concealment roll rather than two 50% concealment rolls.)
Ethereal creatures are invisible. Since ethereal creatures are not materially present, spot checks, listen checks, and blind-fight do not help locate them. Incorporeal creatures are often invisible. Blind-fight does not help creatures find or attack invisible, incorporeal creatures, but spot checks and possibly listen checks can help.
Invisibility does not thwart detect spells. Rather see invisibility and true seeing will negate both the -4 penalty to attack rolls, as well as the 50% concealment innate to invisibility (improved invisibility has a separate 50% concealment effect which is not negated).
Since some creatures can detect or even see invisible creatures, it is helpful to be able to hide even when invisible.
