This spell allows the caster to seize control of an elemental summoned by someone else. The priest has a 50% base chance of success: the roll is adjusted by the difference in level or Hit Dice between the priest and the elemental. This roll is further modified by the difference between the original summoner's Wisdom and the caster's: the difference between the two is a bonus added to whomever has the greater Wisdom.
Only one attempt can be made per creature; if the priest does not seize control of the elemental, no future efforts will succeed. If the effort is successful. the elemental obeys the wishes of the priest for the remainder of its stay on the physical plane.
