Your critical hits can knock the sense out of your foe.
Benefit: When you score a critical hit with an attack, you can forgo dealing extra damage to instead deal 1d4 Wisdom damage. Weapons with a critical multiplier greater than x2 deal +1 ability damage for every additional multiple (thus a Concussion delivered with a greataxe deals 1d4+1 Wisdom damage).
