Your critical blows leave foes in shock.
Benefit: When you score a critical hit with an attack, you can forgo dealing extra damage to instead deal 1d4 Constitution damage. Weapons with a critical multiplier greater than x2 deal +1 ability damage for every additional multiple (thus Shock delivered with a greataxe deals 1d4+1 Constitution damage).
