Phantasmal Incarnation

By drawing upon the deepest fears of a group of creatures, you create illusory creatures within their minds, visible only to them. Each creature within a 30-foot radius centred on a point of your choice within the spell’s range must make a Wisdom saving throw. On a failed save, the creature becomes Frightened for the duration of the spell. The illusion draws upon the creature’s worst fears, manifesting its most horrendous nightmares as a relentless threat. At the end of each frightened creature’s turn, it must succeed on a Wisdom saving throw or suffer 4d10 psychic damage. On a success, the spell ends for that creature.
