The spirit box It is spelled to call forth whatever spirit is needed at the time and bind it to a vessel you place inside, here is the tricky part, you don't get to say what spirit, the box chooses FOR YOU even if it's a BA spirit that you need.

So buyer beware. You don't get to choose which spirit comes forth so you must know that. If you need revenge this box will bring forth a spirit that specializes even if it's a demonic entity.
