Planar Eviction
Tier 2 Epic conjuration
Casting Time: 1 action
Range: Touch
Components: V, S, M (two native flowers from two different planes)
Duration: 1 round
You make a melee spell attack against a creature you can reach. On a successful hit, you banish the creature, scattering its form across the planes. The creature disappears from its space and over the course of its banishment, it takes 10d10 acid, cold, fire, lightning, necrotic, or radiant damage (your choice).
At the start of each of your turns for the duration, a creature banished by this spell takes an additional 10d10 damage of a different type from the list (your choice) then returns to the space it left or to the nearest unoccupied space if that space is occupied.
At Higher Levels. When you cast this spell as a tier 3 Epic spell, the duration of the creature’s banishment increases by 1 round.
