When a PC want to aim to the opponen's head: the rules say regarding Aim " If the character spends one maneuver aiming to do this, their next combat check suffers . If they spend two consecutive maneuvers aiming, the combat check suffers instead."
OK. Let's say, the PC have 3 uncancelled . Does he deal damage as usual or because he targets the head and he succeed, there is extra damage like uncancelled x2 ?
I can't find specific damage rule when aiming vital target.
