Kneecapper

Description
Like a gangster in a cheap mafia movie, you've got knee-seeking aim. You can snap an egg's leg like a twig and leave 'em squirming in pain. Ain't no one's gonna be late with their protection money now, see?

Effects
When you use Kneecapper, you spend 6 Stamina and 2 AP. You make an attack against an adjacent enemy. This attack must be a Called Shot to a leg, and incurs the normal -2 penalty for melee weapons. If the attack hits and deals damage, the enemy's leg becomes Crippled, and they must roll a VIG save against your damage to resist falling into pain and writhing In Agony.
