The "spell" inside Clan Castle.

We'll sure get attack each time we left and finish of shield time. Therefore, i suggest all chief to request a spell and keep in our cc before left village.

1st all, how strong defensive for our cc village is depending whats level of the spell. Lvl4 poison will be 4x powerful ofcoz. Same with others spell.
The plan is like that, when cc get damaged, the spell release at specific range, and our village will get extra protection against the invaders.
Poison and earthquake spell will kill. Well, haste spell will improve the speed our cc troops for defending.

Haha, have Fun guys. (^O^)

This would make three starring more difficult at higher levels, especially TH11. So, I don't see this happening, sorry.
