Abyss Key

Abyss Keys are unique key items used to unlock sealed doors within Abyss dungeons, granting access to bonus chambers containing Abyss Artifacts, rare loot, and hidden boss encounters. Each key is consumed upon use, and they cannot be crafted or purchased from merchants.

Abyss Keys are found as rare drops from certain bosses, hidden in treasure chests throughout the overworld, and awarded for completing specific exploration challenges. Players should save their Abyss Keys for the most rewarding dungeon doors rather than using them on the first sealed chamber they encounter.
