As an action, a creature that you can see within 5 meters is not hindered by difficult terrain made of sand.
You can target one additional creature for each additional mana or psi expended. The creatures must be within 5 meters of each other when you target them.
You can expend 1 additional mana or psi so the creature can move across any sandy surface—such as loose sand or quicksand—as if it were harmless solid ground.
If you target a creature submerged in sand, the spell carries the target to the surface of the sand at a rate of 10 meters per round.
