You bend time around up to 6 creatures of your choice within a 30 feet of you. Each target must succeed a Constitution saving throw or be restrained for the spell's duration. In addition, on a failed save, each creature takes 4d8 force damage, or half as much on a success.

A creature affected by this spell makes another Constitution saving throw at the end of each of its turns. On a successful save, the effect ends for it.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by a d8 for every spell level above 4th.
