The folks behind the popular Spheres of Power and Spheres of Might books is back to finish off their trio with Spheres of Guile. But that's not all, as they've also got Ultimate Engineering. If you're looking to expand your Pathfinder games, check out their Kickstarter campaign.
From the campaign:
Welcome to Spheres of Guile and Ultimate Engineering, two new supplements for your Pathfinder 1st edition game that finishes the spheres system and the reimagining of the game we started years ago with Spheres of Power. If you love options and creating new and imaginative characters, games, and worlds beyond the scope of what the rules assumed was possible, then this is the kickstarter for you!
The campaign is up and over its funding goal with 26 days left to go.
