Evasion (Ex)
Source: Ultimate Combat, p. 17
A ninja can avoid even magical and unusual attacks with great agility. If she makes a successful Reflex saving throw against an attack that normally deals half damage on a successful save, she instead takes no damage. Evasion can be used only if the ninja is wearing light armor or no armor. A helpless ninja does not gain the benefit of evasion.
Feat: A ninja may gain any feat that she qualifies for in place of a ninja trick.
