I used this spell to try to win arena with some lower level heroes. Let's just say it gets you to the last fight, but it's not that effective against Umberdroths and Obsidian Golems. I think it they should probably make it not stackable, but it is the only Air Spell worth casting most battles.
On another note, casting it 20 times in the same fight makes the game lag like crazy. [e digicons]O:)[/e]
