Slipskin (3.5e Invocation)

Pick any humanoid you have seen in the past. You may seen this person through mundane or magical means including seeing with your eyes, the Chain of Eyes (Complete Divine) spell, and scrying. You may not pick a person you have seen in a drawing, book, or picture. You may change your appearance to look like that humanoid for 24 hours or until you recast this invocation. You may also choose appearances of humanoids you have seen changed with the Disguise Self spell or similar ability. For purposes of determining choosable appearances and prestige classes, this invocation counts as the Disguise Self spell.
