The Crucible is filled with strange and wondrous creatures, belonging to many disparate Houses. And if that inherent variety wasn't enough, the introduction of mysterious dark aember has welcomed in a flood of mutation, as once-familiar giants, thieves, demons, knights, and others become forever changed. Some rejoice in the changes, while others see them as heresy and fight to eradicate the dark aember and its effects. Which side of the conflict will you take?

Within the Mutant Invasion! roleplaying supplement pack for Genesys, you'll find 40 oversized cards stuffed with information for players and Game Masters alike, expanding on the content included in the Secrets of the Crucible sourcebook. You'll encounter a brand-new playable species, rules for incorporating the mutative dark aember into your own games, adventure builders, locations, and over 30 NPC adversaries to populate your adventures. If you're planning to take your Genesys adventures to the Crucible, the Mutant Invasion! supplement pack brings even more of the diversity and wonder that makes the Mass Mutation set of KeyForge decks so compelling.
