Banishment enables the character to force extraplanar creatures out of the character's home plane. Up to 2 HD of creatures per caster level can be banished. To target a creature, the character must present at least one object or substance that it hates, fears, or otherwise opposes. For each such object or substance, the character gains +1 on the character's caster level check to overcome the target's SR (if any) and +2 on the saving throw DC.

At the DM's option, certain rare items might work twice as well.
