Disguise (CHA)

(Player's Handbook v.3.5 variant, p. 72)

Special

Magic that alters your form, such as alter self, disguise self, polymorph, or shapechange, grants you a +10 bonus on Disguise checks (see the individual spell descriptions in Chapter 11: Spells). You must succeed on a Disguise check with a +10 bonus to duplicate the appearance of a specific individual using the veil spell. Divination magic that allows people to see through illusions (such as true seeing) does not penetrate a mundane disguise, but it can negate the magical component of a magically enhanced one.
You must make a Disguise check when you cast a simulacrum spell (page 279), to determine how good the likeness is.

If you have the Deceptive feat, you get a +2 bonus on Disguise checks.
