I imagine that there are official ways to do stat blocks, but because Loviatar is a fanzine I have to lay them out in a way that makes sense to me. Below is an example of how I'm going to be doing my AD&d 2e stat blocks. I hope it makes sense to you, too. I provide a lot of details (perhaps too many), but that's what I like to have when I play.
