The Maven

From publisher blurb:

The Maven is a new expert core class for the Pathfinder 1e system. The Maven seamlessly blends mundane skill with utilitarian spellcasting, garnering a reputation as a master in their field of expertise with a flair for the extraordinary. At their core, a Maven is a perfectionist, striving for nothing less than excellence with an understanding of their craft that far surpasses ordinary beings. In some ways, a Maven is not only a savant in regards to their chosen field of focus, but they are also a chameleon of sorts, making magic appear to be a result of learned accomplishment or athletic achievements rather than magic itself.
