From publisher blurb:
Interjection Game's gadgeteer base class revels in modularity. A well-balanced gadgeteer spends her gadget slots to slap gizmos and thingamabobs onto a custom weapon or two, then spends the rest on fanciful gadgets with loads of options each! The latter of these- whale oil cannons, spy cigars, and more- have always been the sexier topic, for they are evocative where a toolbox of creation is more of a sandbox tool, and so it was that custom weapons never got an expansion until now.
Pile on brand new combat bonuses for your gadgeteer's custom weapons with options ranging from emergency combat drugs and means to protect yourself from ability damage to self-damaging swift action nonsense!
