Desiccate

You extract the liquid from a creature you can see within range. It must make a Constitution saving throw. If it fails, it takes 4d10 Necrotic damage and is poisoned, taking half of that on a successful save. At the end of each of its turns, an affected creature must make a Constitution saving throw. If it fails, it takes 2d10 Necrotic Damage. On a successful save, the spell ends. A creature killed this way turns to dust. Creatures that contain no liquids are unaffected by this spell.

At Higher Levels When you cast this spell using a spell slot of 5th level or higher, this spell does an additional 1d10 damage per level above 4th.
