Bosses

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 five bosses per run on 0 to 4 BSC difficulty levels. On 5 BSC difficulty the player can defeat four of the six keepers.

There are currently six keepers in the game: The Concierge, Conjonctivius, The Time Keeper, The Giant, The Hand of the King, and The Collector.

First bosses
As the first boss, the player may find one of these two, depending on the path that they take.

The player must have absorbed both the Vine Rune and the Ram Rune in order to take this path.
