Earth-Shaking Thump (Recharge 5-6)

The mei jiao shou rears up and lands heavily, kicking up a shower of debris and rattling and cracking the ground. Each creature in contact with the ground within 30 feet of the mei jiao shou must make a DC 16 Dexterity saving throw. On a failure, a creature takes 22 (4d10) bludgeoning damage and is knocked prone. On a success, a creature takes half the damage and isn't knocked prone. The area then becomes difficult terrain.
