One of the things I don’t like about running combat encounters? Keeping track of all of the stat blocks. Somewhere along the way, I started creating tables that listed the stats for the creatures I was including in combat, along with some notes about what actions they would be taking in combat. And now, I’ll share this handy technique with you.
Then, fill in the stats for the creature or creatures that you are going to include. I like to print these out, and they don’t take up much space, but do let me have a variety of creatures all together on a single page. With the first edition, I would sometimes summarize, or leave off information I wasn’t going to use, but it sure helped with big set-pieces to keep everything straight.
