When you are missed by attack from sword or similar weapon, use reaction to lock weapon. When weapon is locked, it cannot be used to attack, nor can locking weapon. Wielder of locked weapon can use Bonus Action to attempt to break lock with contested check Strength (Athletics) or Dexterity (Sleight of Hand), chosen by contestants. Lock can be broken at will by locker. If locked creature attempts to move away, repeat contested check. On a fail, the locked weapon is dropped.
