PEAK’s Final Ascent update introduces the GLOOM biome, where players risk accumulating potentially fatal sleep damage while beneath its mist. The article advises using light sources to create safe areas, making careful use of the biome’s tools essential for crossing it safely.

Five stationary Belltowers can be activated throughout the GLOOM; each provides a safe zone and can burn approaching large ghosts, while activating all five earns the Bellringer badge. Players can also find candlesticks in luggage to create temporary portable safe spaces and burn ghosts, but their limited charge means they should be saved for time spent under the mist; frogs and crows are additional hazards.
