From publisher blurb:
Find a Path to the Stars!
Advanced technology in the Pathfinder Roleplaying Game makes you wonder how it might fit into the Starfinder Roleplaying Game, including new rules from Arcforge: Technology Expanded and Arcforge: Psibertech. While we could have rewritten rules for Bonded Mechs, the Helmsman class, and so on from the ground up for Starfinder, who needs all that work to bridge both systems? The solution: Arcforge: Star*Path!
This amazing book is a guide for everyone who wants to take their favorite things from the Pathfinder Roleplaying Game and bring them into the Starfinder Roleplaying Game, offering more detailed and holistic legacy conversion rules that should enable most anything from the expansive Pathfinder Roleplaying Game universe into the new frontier of sci-fi gaming. What’s more, Arcforge: Star*Path contains extensive rules for taking things back the other way, enabling players and GMs who love the familiar Pathfinder Roleplaying Game rules to enjoy the new classes, weapons, monsters, and more introduced in the Starfinder Roleplaying Game.
You’ll find tons of rules, notes, and advice for dealing with classes, archetypes, races, gear, and more! Plus, there’s a whole section of brand-new options, with nearly 30 feats and class features like solar renewal, Cosmic Variance, and Void Spell, as well as 7 all-new archetypes like the Ace Greaser, Starknight, Uplink Warrior, and Zenith Marine! Whichever your favorite system, Arcforge: Star*Path provides you a wealth of rules and options for unifying the best parts of each to create countless new characters, stories, and adventures!
