"Invisible to the enemy until it is too late. Triggered when a monster steps on it, deals large damage to a small area. Place close to buildings or use walls with gaps to group attackers in a small space."
The booby trap is the first land mine of sorts available. With a level 9 Town Hall you are allowed 60 of these. Booby Traps, like Cannons and Lasers can hit an unlimitted number of targets, although once they are triggered they will need to be rebuilt. While this structure cannot be upgraded there is now a seperate building called the Heavy Trap that is triggered only by more advanced monsters and deals higher damage. Flying monsters cannot trigger Booby Traps, although they do take damage from them if flying directly overhead. The damage to flying monsters seems to be far less than ground monsters would take.
