Choose a creature you can see within range. The target is engulfed in flamelike shadows and must succeed on a Wisdom saving throw or take 10d10 psychic damage and become frightened for the duration. While the target has line of sight to you, it has disadvantage on saving throws against this spell.

At the start of each of the target’s turns before the spell ends, the target must succeed on a Wisdom saving throw or take 11d10 psychic damage. Each time the target fails a saving throw after the first round, the damage increases by 1d10. On a successful save, the spell ends.
