Exhaustion

A purple and green beam of energy streaks from your hand toward a creature you can see within range. The target must make a Constitution saving throw. On a failed save, the creature gains one level of exhaustion. Casting this spell on a creature multiple times can cause them to gain multiple levels of exhaustion.

All levels of exhaustion caused by this spell are removed from a creature when they finish a short or long rest.

At Higher Levels. When you cast this spell using a 5th level spell slot or higher, you can choose an additional target per spell level above 4th.
