Overwhelming Blow

You throw your weight into a powerful attack that leaves you vulnerable. Make a melee Strike. This counts as three attacks when calculating your multiple attack penalty. If this Strike hits, you get a critical hit. If you roll a critical hit, your weapon or unarmed attack also gains the deadly d12 trait (this replaces any deadly trait it already has). Whether or not you hit, you become Stunned 1 and are until the start of your next turn.
