Baba Yaga's Crushing Hug

 You channel the wrath of hags, wrapping your arms around a creature within range. Your arms gain an appearance of that of a warty gnarled hag. Make a spell attack against a creature within range, the target takes 9d6 bludgeoning damage and if the creature is large or smaller it is grappled. A grappled creature can attempt to escape at the end of it's turn by making a strength saving throw against your spell save DC. On a successful save it escapes the grapple and the spell ends, on a failed save it takes an additional 2d6 bludgeoning damage and remains grappled. On the start of your next turns if you spend any action other than maintaining concentration on the grapple on the target the spell, and the grapple ends.
