Choking Claw

You create a black taloned claw of shimmering magical energy. The claw can attack any creature within 30ft. of itself, make a melee spell attack against a creature within range, on a hit the creature takes 2d8 slashing damage, and must make a Strength saving throw or be grappled. At the start of the creature's turn it can reroll the Strength saving throw, at the end of the creature's turn it suffers 2d8 slashing damage as the claw begins choking it out. The caster can move the hand to any location within 30ft of the claw, the claw then winks out of existence and reappears at the designated location. The claw cannot be farther than 120ft. from the caster, if it is outside of that range the spell ends.
