Summon Elemental

A spell used to summon elementals, usually water elementals, or elemental conglomerate of air and water. Though a presumably it could be used to summon fire, wind, or earth elementals as well.

The caster uses the forces of nature to create a water elemental. He summons the forces of air and water and combines them into simulacrum to defend the lands. They are excellent creatures, and will never turn upon their creators. The element of water was chosen because it is persistent as in the state of erosion, and is the opposite of fire, which seems to be the element that orcs favor.
