Martial Archetype: Prosthetist (Patreon)

The archetypal prosthetist is a fighter that lost a  limb and spent time learning how to create battle-ready prosthetics, to jump back into the  fray. To become a prosthetist, a fighter must have  ample knowledge in the crafts smithing and  tinkering. The battle prosthetics almost function  like a regular limb and are in many ways better  than your actual limb.
