I believe you should be able to donate spells and so do many of my friends. Now I know it could be a big problem if you had 6 extra spells, so think it should work like this. At clan castle level 3 your clan castle can hold one spell and at clan castle level 6 it can hold two. This would be a great incentive for low level players to make their clan castle level 3 because most people in the silver league don't want to upgrade to level 3 for 800,000 gold and just 5 more troops available. The spell would not be available for defense if an enemy comes in range of your clan castle. To use the spell in offense there could be separate buttons for the two spells (if you have them).
Please tell me what you think of the idea!
