Master Disarm (3.5e Feat)
From D&D Wiki
Master Disarm [General]
You are an expert at disarming your opponent.
You gain an extra +2 on the disarm check when using the weapon you have Weapon Focus in. If the weapon you are using is being used in one hand, the other if free and you could wield the disarmed weapon in it you can transfer the weapon to your off hand. Alternatively rather than have if fall in the square you can have it move d3 squares from that square in a random direction (as a grenade like weapon.)
You can only take your opponents weapon if you attack unarmed, otherwise it falls at the feet of the defender.
