If you use Latex for your word processing and also run a D&D game (two groups of people which I imagine actually have a decent-sized intersection), then I can highly recommend evanbergeron’s Github project to make a Latex template that looks like the official Dungeons & Dragons reference books. Look how beautiful it is!
If you want to use this template, just download the stylesheet from the Github project page. Even better, if you want to contribute, then your help is more than welcome! The project is still in very active development. While we’ve managed to replicate most of the features of the reference manuals, some issues remain.
