tidal surge
Class: druid : 5 cleric : 5
Domains: water
Syntax: cast CLASS tidal surge on TARGET

This spell will draw all of the water in the atmosphere for miles and miles around to a place above

  and behind the caster.  The water is condensed into the form of a massive wave that is directed at the target.  The wave 
  may knock the target down as well as force him to drop his weapons.  The force of the water may also keep him from 
  moving until he regains his senses.  Because of the size of the wave, nearby targets may be hit as well.
