Banishment

A banishment spell is a more powerful version of the dismissal spell. It enables you to force extraplanar creatures out of your home plane. As many as 2 Hit Dice of creatures per caster level can be banished in a 30-foot radius, and creatures who are closest to the burst's point of origin are affected first. Dismissal: This spell forces an extraplanar creature back to its proper plane if it fails a Will save. If the spell is successful, the creature is instantly whisked away.
