Description: You can quickly obtain a weapon even in desperate situations, and can discard weapons to confuse and disorient.

Prerequisites: DEX 13, Base Attack Bonus +6, Combat Reflexes, Himitsuheiki Novice

Required for: Himitsuheiki Master

Once per round, any time you are without a weapon you may make a spot check (Base DC 10) to find a new weapon. If there is conceivably any sort of usable weapon in your immediate area you may pick it up as a free action (or as part of a charge or movement if it is not in your immediate grasp).

You gain a +4 bonus when feinting in combat if you drop your weapon (shoving it towards your enemy or entangling it on his weapon) as part of your attack.
