Temporal Collapse

You collapse time around a target creature within range. The creature must make a Constitution saving throw. On a failed save, Roll 1d8 and the creature suffers rapid aging. The Creature also takes 8d8 necrotic damage, and its speed is halved for 1 minute. On a successful save, the creature takes half damage and suffers no other effects.

At Higher Levels: When you cast this spell using a spell slot of 7th level or higher, the damage increases by 1d8 for each slot level above 6th.
