Ekriessa's Time Trap

You manipulate the pattern of time inside a 30-foot cube within range. Up to six creatures of your choice in the area are ripped from the natural flow of time, and must make an Intelligence saving throw. On a failed save, the creature takes 2d10 psychic damage and is stunned for the duration, caught in a time loop. On a successful save, the creature takes half damage and is able to keep itself anchored in its correct timeline.

The spell ends for an affected creature if it takes any damage.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d10 for each slot level above 4th.
