Locating explosive beetles in The Marrow
Three fiery arthropods inhabit the skeletal landscape, each leaving distinctive markers. Follow crimson traces through calcified tunnels to discover their hiding places.
Initial marker position

The first evidence appears on a bone platform within the central cavern complex. Engage cautiously with the volatile creature – its detonation attacks require precise evasion. Secure the dropped crystal after defeating it.
Eastern territory marker

Navigate to the eastern cliffs near spiked hazards to discover the second clue. The armored foe here employs area-denial tactics, demanding strategic positioning during combat.
Western highground marker

The final indicator rests on elevated terrain in western sectors. Enhanced mobility skills prove advantageous when confronting this opponent’s unpredictable explosion patterns.
