Hmm.. I think Shikamaru probably knows how to use it well, and you can always ask the network. They're pretty receptive to us. [ It's like high school and they're the athletic varsity lacrosse team. ] And yeah, no property damage. Unless you punch the walls of the battledome. Those crumble, as I learned from shooting a gun through it. [ That section of the wall was swiss cheesified. ]

On the bright side, the entire thing repairs itself the next day so don't worry about demolishing it. The same thing applies for the apartment you picked out. [ Temari one time demolished the wall between Ino, and Tenten's room and Shikamaru's room. That was an interesting experience. ]
