Tendon Cut (Combat, Critical)

Your critical hits can cause a foe to move awkwardly.

Benefit: When you score a critical hit with an attack, you can forgo dealing extra damage to instead deal 1d4 Dexterity damage. Weapons with a critical multiplier greater than x2 deal +1 ability damage for every additional multiple (thus a Tendon Cut delivered with a greataxe deals 1d4+1 Dexterity damage).
