this thing is just a monster! every time i am near it, it just takes up all the mob spawns in the surrounding area. ur inventory will be full after like 10 minutes collecting stuff from this thing! my friend actually made this and since his specialty is redstone devices, he hasnt put this up. if u want to not have to worry about mobs anymore, get this tower. as a little joke he put jukeboxes inside of the waiting room just to pass time.
