Combat Martial Arts

The character is skilled at attacking and dealing damage with unarmed strikes.
Prerequisite: Base attack bonus +1.
Benefit: With an unarmed strike, the character deals lethal or nonlethal damage (the character’s choice) equal to 1d4 + the character’s Strength modifier. The character’s unarmed attacks count as armed, which means that opponents do not get attacks of opportunity when the character attacks them unarmed. The character may make attacks of opportunity against opponents who provoke such attacks.
Normal: Without this feat, a character deals only 1d3 points of nonlethal damage. Unarmed attacks normally provoke attacks of opportunity, and unarmed combatants cannot normally make attacks of opportunity.
