Time Wave

You release a wave of temporal in a 15-foot cube originating from you. Each creature in that area must make a Constitution saving throw. On a failed save, a creature takes 2d8 force damage, is pushed 10 feet away from you, and is aged or rejuvenated by 1d4 years (your choice). On a successful save, a creature takes half as much damage, is not pushed, and is not aged or rejuvenated.

At Higher Levels: When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d8 for each slot level above 2nd.
