elemental swarm
Class: druid : 9
Syntax: cast CLASS elemental swarm on TARGET

This spell will unleash the fury of the elemental planes on the caster's foes. A portal will open to a random

  elemental plane and an elder elemental will come forth to aid the caster.  The elemental will fight until it is slain or until 
  the caster's enemies are killed.  If the elemental is slain, another portal will open to a different elemental plane.  
  This will continue until the caster is dead, until his or her foes are all dead, or until an elemental has been called 
  forth from each of the planes of earth, air, fire, and water.
