You become angry and flustered under stressful circumstances.
Benefit: If you suffer any damage during combat, you must make a DC 15 Will save or become enraged. While enraged you suffer a -2 penalty to your Armor Class and you cannot use any Charisma-, Dexterity-, or Intelligence-based skills (except for Balance, Escape Artist, Intimidate, and Ride), the Concentration skill, or any abilities that require patience or concentration. You cannot cast spells or activate magic items that require a command word, a spell trigger (such as a wand), or spell completion (such as a scroll) to function. You can use any feat you possess except Combat Expertise, item creation feats, and metamagic feats. This enraged state lasts for a number of rounds equal to 3 + your Constitution modifier and cannot be ended prematurely. This penalty stacks with those from the use of the barbarian rage ability, resulting in a -4 AC penalty.
