Ethereal Banishment - Old Empire

This spell temporarily sends one creature into the Ethereal Plane. The subject is trapped in the Ethereal Plane for the duration of the spell unless released by the caster, any other attempt to return to the Prime Material plane will fail, except by the intervention of Powers or a wish spell. At the end of the spell, the creature is returned to the plane it was banished from. An unwilling creature receives a saving throw vs. spell to avoid the effect.

The material component for this spell is a one-eighth of a vial of oil of etherealness, or oil from a creature native to the Ethereal plane.

Notes: Uncommon in the Old Empire; otherwise very rare. As a Forgotten Realms Old Empire spell, initial exposure requires a mentor or a read Southern magic spell.
