Aeythral Distortion

You create a shimmering field of warped and twisted aeythra in an area that you can see within range. Until the spell ends, the disrupted magic fills a 5-foot cube. Any creature in the field’s space when you cast the spell takes 1d6 psychic damage. A creature is also affected when it moves into the field’s space for the first time on a turn or ends its turn there.

The spell’s damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
