Magic spells comprise a good faction of troops in the game. Clash of Clans, and these, like mobile troops, can be ordered and donated to your companions. Find out how with this short guide from Mobailgamer.
Request and donate spells in Clash of Clans
As with simple troops, spells on Clash of Clans you'll need to order them through the clan chat, but to make it more formal, you have to click on the clan castle, there it says “ASK FOR TROOPS” and a block where you are going to write exactly what you need, it can be archers, wizards, even specific spells such as lightning or healing. That message will reach the members of the clan through the chat and someone will always answer your call.
