Tornado Spell

Hello!
So I thought of this new spell, the tornado spell. I haven't got an image of what it could look like, but the basic idea is that when you spawn it wherever you want,
a small tornado will appear, and circle around a small radius (maybe 3-5 tiles, according to how upgraded it is) doing damage to whatever has been trapped within
it's reach.

I think it should cost around 25,000 elixir, need a level 5 spell factory, and be made in around 45 minutes. Again, I do not know what it could look like, that's up to
Clash of Clans, but I think it would be a great addition to the game!

Thanks for reading!
