Details about Donating spells.
I know that a lot of people have talked about this, but I have some details. My idea is that donating spells would work like donating troops, except a separate section of the clan castle. After you get to clan castle level 3, you should be able to hold one spell. At clan castle level 5, you can hold 2. When you attack, donated spells would have their own placement marker. Also, when somebody requests for troops, there would be a button for donating troops and donating spells. I'm still figuring out how this would figure in to the number of troops donated.
