Oh it will be a little more than a combat ring.

One very big rule this world seems to abide by is no weapons. Anyone that had a weapon before getting here it's suddenly gone. Making any weapons can be consider a criminal offense. Some of the only things that can normally by past that are wooden swords.

The leeway I was given means that as long as it on the grounds of my build, weapons that crafted in this world can be used there. Weapons can also be made on the grounds of the being with interference.
