Temporal Withering

You release a surge of temporal withering in a 15-foot radius sphere centered on a point within range. Each creature in that area must make a Constitution saving throw.

• On a failed save, a creature takes 3d6 necrotic damage and gains one level of exhaustion.

• On a successful save, a creature takes half damage and doesn't gain exhaustion.

Casting this spell at a higher level: When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.
