Talia's Nightmarish Vision

You tap into the minds of 10 creatures you can see within range and create an illusory manifestation of their deepest fears, visible only to those creatures. The targets must make a Wisdom saving throw. On a failed save, the targets become frightened for the duration and have disadvantage on wisdom saving throws. At the end of each of the target's turns before the spell ends, the targets must succeed on a Wisdom saving throw or take 2d10 psychic damage. On a successful save, the spell ends. 

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d10 for each slot level above 3rd.
