You are especially good at pulling your punches.
Benefit: You can make mêlée attacks that do non-lethal damage with no penalty to hit. This ability includes edged and piercing weapons, unarmed strikes enhanced by a Super Ability (e.g., Strength, Dexterity, etc.), and thrown objects, but not projectiles and firearms. How you manage to attack with, say, a lance and not do lethal damage is up to you to describe.
Normal: To deal NL with a lethal weapon usually incurs a penalty to hit -4.
