You are trained to make sharp, controlled blows to your opponent’s weapon, creating an opening for an attack. Upon a successful Melee Attack, you may choose to forgo inflicting any Damage. If you do so, your opponent may not Oppose further Melee Tests with any Melee Skill until the end of their next Turn, and Melee Attacks made against them gain the benefit of Advantage. They may continue to oppose attacks with the Dodge Skill. This Talent is of no use if your opponent has a larger Size than you (see page 360).
