My party and I are going to have a massive battle soon, and i was wondering, is it a good idea to have hurl 2 greater storm elementals at the mass of the enemy. Using their thunder (which is something like 20 d6 with a range of 60ft in all directions) and lightingn (which is 10- 15 d6 range 120 feet in a line) they would attack the enemy and each oth4er with their attacks, but since thunder and lighting attacks actaully heal them, they would just become a self healing storm of destruction. Pretty good no?
