7th Floor of the Tower

Can only be accessed by the 1st or 4th floor. This floor is pitch black all over, and your abilities are stripped in this space. Finding the next door is a gamble, since you can't feel your way around.

Every door on this floor leads to the 3rd, 4th, and 2nd floors, at random, and only one door leads to the 13th.

You basically role a die, and get it over 13, and you make it to the six floor, get it anything below, and you go back to one of the stated rooms.
