Biodefense Chamber B

Biodefense Chamber B is a repeating room located on the Celestial Archives, Alinos, Vesper Defense Outpost, and Arcterra. It appears in Metroid Prime Hunters. The chamber is always the ultimate room of every second Stronghold Void on all four of the worlds, and is the location of all Slenches.
==Description==
Biodefense Chamber B is much larger than Chamber A. The walls and floor are constructed of a purple alloy, with gaps filled by indestructible Force Fields through which diamonds and what appear to be buzzsaws with blue cores are visible. The latter recurs throughout the chamber. The wall facing the entrance, and the ceiling feature all of the mechanisms that the Slench requires for battle. The sole exception to this is in the final room with the fourth Slench, which is on the ceiling. The floor is marked by a circular pattern that resembles a dial, and two hexagonal portholes through which line shines upwards.
Destroying the Slench yields an Octolith and Energy Capsules. After collecting these, Samus can leave Biodefense Chamber B and the Stronghold Void
