From publisher blurb: This supplement provides extra details for the School of Arcanum, a Pillar of Magic known by thaumaturges in the world of Ainerêve. This supplement presents the official Artificer Class, in the format following the Eldritch ReClassified supplement, but one does not need to own that work to understand its use here. A recap of the optional Character Class rules is presented, followed by the addition of the Artificer Class.
