You are able to disarm an opponent with a careful flick of the wrist or a well-aimed blow to the hand. Upon a successful melee strike as the attacker, you may choose to sacrifice the Damage. If you do so, your opponent loses a held weapon, which flies 1d10 feet in a random direction. If you wish, you may lose Momentum to pluck the weapon from the air with a flourish. This Talent is of no use if your opponent fights unarmed, is securely attached to their weapon, or has a larger Size than you (see page 360).
