Gloomhaven: Jaws of the Lion is a standalone game that takes place before the events of Gloomhaven. The game includes four new characters — Valrath Red Guard (tank, crowd control), Inox Hatchet (ranged damage), Human Voidwarden (support, mind-control), and Quatryl Demolitionist (melee damage, obstacle manipulation) — that can also be used in the original Gloomhaven game.
Gloomhaven: Jaws of the Lion is aimed at a more casual audience to get people into the gameplay more quickly. All of the hard-to-organize cardboard map tiles have been removed, and instead players will play on the scenario book itself, which features new artwork unique to each scenario. The last barrier to entry — i.e., learning the game — has also been lowered through a simplified rule set and a five-scenario tutorial that will ease new players into the experience.
