Classy Characters: Robomancer

From publisher blurb:

Classy Characters: Robomancer is a Pathfinder-compatible sourcebook about the robomancer, a summoner archetype that summons a part-living, part-machine eidolon from a strange plane where flesh, metal, magic, and technology are equally common. This eidolon--called a "mechrilon"--has mechanical body parts, artificial limbs, and other enhancements that blur the line between living creature and machine.
