Keepers are the bosses in Dead Cells. Each Keeper has their own biome, where the player must defeat them to progress. Currently the player can defeat only three of the four bosses per run.
There are currently four keepers in the game: The Concierge, Conjunctivius, The Time Keeper and The Hand of the King
As the first boss, the player may find one of these two, depending on the path that he takes.
