Deadly Delusion

Choose a creature you can see within range. 

You confront the target with a vision of their own death - the target must make a Wisdom saving throw. On a failure, the target takes 8d10 psychic damage, and cannot speak until the end of its next turn, dumbstruck by what it believes it has witnessed. On a success, the target is unaffected.

This spell only affects creatures who can see, and from whom you are completely hidden.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage increases by 1d10 per level of spell slot above 5th.
