Perfect Self

Perfect Self: At 20th level, a monk becomes a magical creature. He is forevermore treated as an outsider rather than as a humanoid (or whatever the monk's creature type was) for the purpose of spells and magical effects. Additionally, the monk gains damage reduction 10/chaotic, which allows him to ignore the first 10 points of damage from any attack made by a nonchaotic weapon or by any natural attack made by a creature that doesn't have similar damage reduction. Unlike other outsiders, the monk can still be brought back from the dead as if he were a member of his previous creature type.
