On an opponent that is prone, you can use a contested grappling attack using a str or dex check. On a successful str check you grab the opponent limb injuring it (giving it a -2 to its attacks or -5 feet of movement). On a successful dex check you apply a hold to the opponents neck and begin to squeeze (causing 1d6+ dex mod dmg and opponent is restrained). Opponent can make a dex or str check (dc15) on its turn to get free. On a failed save during its turn it suffers 1d6+ dex mod and remains restrained.
