Zen Defense

Zen Defense [Warrior] Prerequisite: Blind Fight, Expertise. Benefit: When unarmoured, you gain an insight bonus to your Defense Class equal in magnitude to your Wisdom modifier, if it is positive. This bonus stacks with the normal Dexterity bonus. If you wear light armour, you get half the normal bonus, rounding up. Characters in medium or heavy armour gain no benefit from this feat. Spells that duplicate the effect of armour count as armour for the purpose of this feat.
