1) By keeping the thrusting weapon’s point leveled at your target you prevent a single opponent from rushing you and entering into Grapple range. You gain a Free Dice for all Attacks of Opportunity against a single designated opponent when using a thrusting weapon, even if you have no MP left. 2) Also gain an Opportunity Attack against any opponent which attempts to close to Grapple but has Improved Grab, Graceful Rush, Improved Grapple, or some other feat which normally confers immunity from OA when initiating Grapple. This feat works with any primarily thrusting weapon but not with weapons with a secondary thrusting capability. The OA is always considered a thrusting (Pierce) attack.
