d100 Boulders

Obviously I'm now scraping the bottom of the barrel and have used up all my ideas. This will be a terrible useless table you can use indoors or outdoors when you need to roll large rocks. You should roll on this table as many times as possible every game.

I would use for landmarks in hex crawls and caves or when landscape getting boring.
