The mage casts this spell to force a creature from other
dimensions back whence it came. The mage speaks the incantations while
pantomiming pushing something through a portal, and then closing it up. A
portal to the home dimension of the entity appearing in front of the entity to
be dispelled. Compare the effect value of this spell to the entity's greatest
physical attribute. If the result points are equal or greater than the entity's
Spirit, the caster forces the entity back to its home dimension.
