Cutting visions

The user either mutters an incantation or creates a certain hand signal to trigger the spell. Any creature they can see immediately suffers horrendous visions. It ranges from blurry vision, to seeing ghosts, to even being attacked by demons. It may not be a physical manifestation however the target does suffer extensive mental damage. Any creatures being targeted by this spell must roll a Wisdom saving throw with DC 15. On a fail, the target receives 30 damage, and on a success, half as much damage.
