Weapon of Peace

Even though you are
a trained combatant, proficient with any number of
weapons, you don’t relish killing your enemies. It’s
not that you’re afraid of seeing blood, but rather that
disabling a foe is superior to killing someone capable of
admitting defeat. When using a melee weapon that deals
lethal damage to instead deal nonlethal damage, you take
only a –2 penalty instead of –4.
