From publisher blurb: Four Horsemen Present: Gruesome Constructs! In conjunction with d20PFSRD.com and Rogue Genius Games, the Four Horsemen have built a set of horrifying after-market additions for constructs that'll have your players asking for a recall! This product offers new made-to-order templates to turn constructs into an Abandoned (a shield guardian gone horribly wrong), a mythic and sadistic Insane Intelligence (which is just what is sounds like), an angry Unbound (when the elemental animating the golem learns to control the cage construct around it), or a vicious Vivisector (which steals the flesh of the living to emulate life itself)!
