This spell turned the recipient into a sand worm; a man-sized worm that no longer needed to eat, drink, or breathe. The sand worm could easily burrow through sand and loose earth. It could detect heat from living things up to 30 feet (9.1 m) while underground and that ranged was doubled above ground. Transforming into the worm partially healed the recipient.
Sand worms were able to move faster while burrowing than they could on the surface.
This spell required a live worm to cast.
