Okay so first of all... THANK YOU FOR POSTING THIS STUFF! I'm not much of an artist or as good at the little details as some of you are and this list is helping me think about what I may need to put on my own designs.
This sort of stuff is actually a tad fun for me, so thanks much! It's usually rather quite easy, but only when people use the same scales and everyone has the same tropes and things like that. These sorts of charts are really aesthetically pleasing and give it more of a 'game' sense; to me at least. Not sure, tbh. I just love reference materials.
