From publisher blurb: It's Elementary! Legendary Investigators is the latest volume of our class-focused Pathfinder Roleplaying Game player supplements, this time focusing on the detectives, scientists, magic-dabblers and scholars that are encompassed by the investigator class. The legendary investigator redesigned the core class, making certain abilities usable earlier like studied strike, and shifting it to a 5-level casting class but allowing for a wider breadth of study, ability, and training through its 19 different Courses of Study like engineering, naturalism, and the occult. In addition, you get new investigator talents that compliment some of the courses as well as assessment talents that leverage your knowledge against your foes. Complement this with archetypes that shift the focus further like the face-changing and sneaky infiltrator and the old-magic using malice binder, as well as feats Addicted to provide give-and-take dynamics with your character's inner demons and vices. Whether trying to catch the killer fleeing across rooftops, finding the weakness of the monstrosity threatening the city, or digging deep into the dusty tomes of a massive library, the legendary investigator can use their wits and know-how to get the job done.
