|The Guy With A Face|
What class is your character? One level of Pain Taster is an option, but it costs three feats.
At 1st level, a pain taster becomes empowered by pain, and is inured to its effects. She receives a +4 class bonus on saving throws made against pain effects.
Additionally, a pain taster can deal lethal damage to herself at any time to gain a bonus on attack and damage rolls. Doing so is a swift action that deals 2 points of damage to the pain taster, does not require an attack roll, and bypasses any damage reduction the pain taster possesses. For 1 round, the pain taster gains a +1 morale bonus on attack rolls and a +2 bonus on damage rolls.
Every 3 levels thereafter (4th, 7th, and 10th), the amount of damage the pain taster deals to herself increases by 2 and the resulting bonus she receives on damage rolls increase by 1 (to a maximum of 8 points of self-inflicted damage and 5 points of bonus damage to other targets at 10th level). At 7th level, the bonus on attack rolls gained when using this ability increases to +2.
