Pinning Shot (Ex)
At 15th level, the bolt ace can spend 1 grit point while shooting a crossbow and attempt to pin down its target with the bolt. If the crossbow attack hits, it pins the target to a nearby object, to a wall, or to the ground, entangling and staggering the target. While pinned by the bolt, the target cannot move (except by teleportation) until it takes a standard action to free itself from the pinning bolt. This deed replaces menacing shot.
