THis spell helps confuse inferno tower mulitargert most and other defence

Spells with elixir are enough. Sure we can have more elixir based spells, but with DE? No I'd rather not.
Plus this particular spells is too overpowered. Just use freeze instead to stop the infernos or defences from targeting you troops.
