Undead Grasp

Grasping Undead hands sprout from the ground in a 20-foot square starting from a point within range. For the duration, these hands turn the ground in the area into difficult terrain.

Any creature in the area when you cast the spell must succeed on a Strength saving throw or be restrained by the grasping hands until the spell ends. A creature restrained by the hands can use its action to make a Strength check against your spell save DC. On a success, it frees itself.

When the spell ends, the conjured corpse hands shrivel up and sink back into the ground.
