Clash of Clans spell factory overview. You can unlock the factory when your town hall has reached level 5 and you've collected 200,000 elixir. Here, you can create 5 different spells to use during raids. Each spell has a different power -- lightning, healing, rage, jump, and freeze. Upgrade your spell factory to unlock all five!
