You use a weapon to knock down a foe. When you strike an enemy’s body or shield (but not their weapon) with a suitable weapon, you can spend either 1 or 2 Valor Points depending on the weapon you are wielding and call out Crush to knock them down as per that call’s effect.
You can only use this Technique with a Medium Weapon in the form of a hammer or a Heavy Weapon. It costs 1 Valor to use this Technique with a Heavy Weapon in the form of a hammer, and 2 Valor to use it with all other weapons.
You must swing your weapon when you strike to use this ability; you cannot thrust with it. Spears, specifically, are not valid weapons to use this ability with.
