Starjammer Core Rulebook — Sci-Fi Space Adventure for Pathfinder RPG

Your Pathfinder campaign doesn't have to end at the edge of the map. Starjammer is a complete 200+ page core rulebook that takes everything you love about Pathfinder 1E and launches it into space — new alien races for player characters, starship combat rules with the same tactical depth as ground combat, advanced technology and futuristic gear, space-adapted classes and archetypes, and a full interstellar campaign setting with worlds, factions, and conflicts ready to drive your adventures.

Pathfinder Mechanics, Infinite Cosmos

Starjammer isn't a conversion kit or a bolt-on supplement — it's a complete science fantasy experience built on the Pathfinder rules you already know. The alien races offer genuinely different player character options beyond the standard fantasy roster. Starship combat translates Pathfinder's tactical combat into space battles without requiring a separate ruleset. The technology chapter replaces medieval gear with laser weapons, powered armor, and futuristic devices that integrate cleanly with existing Pathfinder magic. If your group loves Pathfinder mechanics but wants to explore the galaxy instead of dungeons, this is your rulebook.
