Visage of Yog-Sothoth

You unleash a torrent of mind rending hallucinations at a creature you within 120 ft. of the visage of Yog-Sothoth. It hears and sees the images within its mind and takes 1d8 + your spellcasting modifier of psychic damage. Additionally, the target creature must succeed on a Wisdom saving throw or be stunned as the images assault its mind. The condition lasts until the end of the creature's next turn.

For every level of spell slot used above 1, add 1d8 to the damage roll.
