As two actions, mummified hands drag a creature that you can touch or see within 18 meters down into a pit of sand. The creature must succeed on a Reflex saving throw or be dragged below the surface into an extradimensional space filled entirely with sand.
While entombed by this spell, the target is blinded, restrained, and starts to suffocate, taking 5d6 bludgeoning damage at the start of each of its turns.
A creature can repeat the saving throw at the end of each of its turns. On a successful save, the effect ends and the target returns to the space it previously occupied, or the nearest unoccupied space.
You can increase the damage by 3d6 for each additional mana or psi expended.
