After an unremarkable career as a chemist Craig died, only to find himself in a fantasy world that operated on game rules. His prior experience translated into a level of the Alchemist class, unfortunately it's an NPC class in this world considered useless in combat, as he discovers after getting captured by kobolds.

Dragged along by a party of beastman adventurers who rescued him, he has to not only survive but figure out his place in this new world where the economy is based on dungeon-delving.
