From publisher blurb: Introducing the latest expansion to the tinker base class, three-time winner of an Endzeitgeist top 10 product of a year award! Remedial Tinkering: Artificial Intelligence focuses on cheating the very directive system that is core to the tinker base class. Automatons using these inventions find limited ways to give themselves directives, usually under very specific circumstances. In addition to directive cheating, Artificial Intelligence introduces several new ways for automatons to use inventions without being directed to do so. As the most easily accessible of these methods only allows for the activation of 1st-level inventions in this manner, this expansion roughly doubles the number of directed-use 1st-level inventions available to the tinker base class.
