Hello, I DM on roll 20, and I find the D&D 5e compendium to be incredibly useful. I am also a player in a pen and paper game where some people can get bogged down by the rules and looking through the 5e players handbook. This makes me want to make a simple iphone app, so that looking up rules is much easier for us. I know I can access the compendium via mobile browser, but it just feels a bit clunky. Can anyone point me towards, or inform me of, the legal complications of this idea? Am I even allowed to do this?
