The Tinker: Master of Modular Mechanical Mayhem

A tabletop roleplaying supplement centered on an inventor who commands mechanical automatons instead of relying on weapons or traditional magic. Players build blueprints, select inventions and innovations, and deploy modular machines with different capabilities. Experienced characters can construct autonomous Alpha units that direct other automatons, while advanced tinkers gain nanobot swarms capable of dismantling and rebuilding materials. The supplement includes a complete base class, progression rules for the tinker and their machines, feats, innovations, greater innovations, 121 inventions, and pregenerated automaton configurations.
