Alchemical Inventors are usually smelled before they are seen, thanks to the apothecary’s store of chemicals and poisons they carry. These chemists often sport mottled and discolored scales or skin, caused by the caustic nature of their obsessions. They raid alchemy shops and magical laboratories to gather more material to fuel their reckless experiments.

Alchemical Inventors can be a great boon to their group, but at a cost. Not only do they require rare, expensive, and often dangerous substances to ply their trade, they tend to be a little unhinged. Their experiments yield powerful weapons and defensive concoctions that can save many lives, but the destruction caused by an experiment gone awry can be terrible.
