obstacles that attacker or the player can remove for gems!
The idea is pretty straight forward these are like all other( except they have a different graphic from the present ones) obstacles in the game so if the player removes it they get a random amount of gem or they get nothing. But the difference is that if it's found wile attacking the attacker's troop will go for it like any other enemy bilding and if destroyed complitly it will either eald a random amount of gem or nothing! Another thing is that it dos not contribute to the overall damage that way even if all other building is destroyed except for this obstacle you still get 3 star
