Usage: cast banishment
Save: negates, one per target

The words and chants which make up this spell disrupt the controlling energies of many summoning and control spells. With the exception of those belonging to the caster, all charmed mobiles within the room must succeed in an immediate saving throw or be banished to an alternate dimension, at least until summoned back by an outside force.

Please note that demons, aerial servants, elementals, and even familiars are considered 'charmed mobiles' for the purposes of this spell, not just mobs subjected to the charm person spell.
