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.
