Publisher's blurb: Old School Hacks Vol 1: Hexcrawling dives deep into the Dungeon Master's Guide rules on wilderness exploration, getting lost, and more, and includes a detailed discussion of the theory, science, and art of building random encounter tables. There's also a world-neutral hex map and five example wilderness encounter tables tied to it. Featuring plenty of combat, exploration, and evocative interaction-based encounters, there's enough material for several months of gaming, as well as a barebones setting that you can expand to create your own low- to mid-level campaign.
