I know this will never happen unless like 5,000 people request it. But I was thinking if there should be defensive spells in the game, like a trap. It can be made in a regular spell factory with another spell capacity. The main one i was thinking is a defensive lightning spell, so if a troop steps into the ring, the lightning spell will be triggered and shock the troops. one obvious con is that if u can place it where ever you want. Then of course people will place it by town hall, so i was thinking if there can be a physical form of the spell, like a tesla and giant bomb. So you can predict where it can be triggered.
edit: How do i delete this, XP
