Lock Swords (Combat)
When an opponent attempts to disarm you with a weapon you are able to lock your weapon with his, limiting his ability to escape.
Prerequisite: Improved Disarm.
Benefit: When an opponent attempts a disarm attempt on you, with a weapon, you gain a +6 bonus to your attack roll to resist the disarm action. If you win the disarm check then you may either immediately attempt to disarm that opponent, as per normal disarm rules, or you may elect to lock your weapon with your opponent’s.
If you choose to lock weapons than your opponent loses his next attack action and must make a successful REF save (DC 10 plus your Dexterity modifier) to break free and make a move action. If your opponent fails this REF save then he cannot move until the beginning of his next turn. For as long as your weapon is locked with his neither one of you may move or make attacks of opportunity. You may elect to end the weapon lock at any time as an immediate action.
