Exorcise

The caster inscribes a chosen fiend, fey, celestial, undead, or elemental's name within a binding rune-filled piece of parchment. Binding runes carve themselves into the creature's body, and at the start of it's turn the creature must make a wisdom saving throw against the caster's save DC. On a fail, the creature must take 3d8 psychic damage or return to it's plane of origin. On a success, nothing happens. The spell will only end under one of three conditions; the caster falls unconscious, the creature is more than 300 feet away, or the parchment containing the runes is destroyed.  

The caster may only use this spell if they know the target's true name.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the target takes an additional d8 psychic damage for each slot level above 4th.
