Uncanny Dodge (Ex)

At 2nd level, an assassin cannot be caught flat-footed, even if the attacker is invisible. He still loses his Dexterity bonus to AC if immobilized. An assassin with this ability can still lose his Dexterity bonus to AC if an opponent successfully uses the feint action against him.

If an assassin already has uncanny dodge from a different class, he automatically gains improved uncanny dodge instead.
