New Dark Spell(The Duplicate Spell
This spell would be able to create a clone of the troop or troops it is used on.For example,If you are runing low on Giants or need some extra Golems,Jest drop the spell and any troop in it's radius get duplicated.Now this may sound over powered but the catch is the clone or duplicate only has half the amount of attack damage and hitpoints.That way u don't have 4 Golems with 5000 hitpoints each.This idea to me sounds really cool and I think it could change the way people attack,So please consider this idea for your next update.
