Piledriver

You’ve developed the skills necessary to hold your own in close-quarters grappling. You gain the following benefits:

• You gain +1 to your strength or constitution
• As one attack as part of the attack action (this can be a later attack in the same action that achieved the grapple) you may attempt to throw your opponent to the ground, make a second grapple check against the opponent, on a success, you deal 3d10 + your strength modifier points of bludgeoning damage to the target and they fall prone, but the grapple ends, they take half damage if the opponent succeeds the contested check, and the grapple ends without the target falling prone.
