Sand Tomb

You attempt to summon a wave of sand that surrounds the target. Force a creature in range to make a STR saving throw against your Move DC, taking 1d10 + MOVE ground damage and becoming restrained on a failure, or half as much without being restrained on a success. If it fails, at the beginning of each of its turns, it may attempt to escape with a STR save against your Move DC. While a creature is restrained, you may continue this move, as an action, to deal an automatic 1d10 + MOVE ground damage.

At Higher Levels: The damage dice roll for this move changes to 2d8 at level 5, 5d4 at level 10, and 4d8 at level 17.
