Welcome! I've been playing roleplaying games for over thirty years, and one thing I've learned is to always keep a Battle Book with me when I'm a GameMaster running a game. Dungeons and Dragons, Call of Cthulhu, Pathfinder, it doesn't matter what system you use. And even now that I run most of my games online, I still keep my trusty Battle Book by my side. That got me thinking: why not share my simple two-part system with you? Well, here it is. I hope it helps you enjoy role-playing games as much as I do.
