This labyrinthine zone in Hollow Knight: Silksong challenges players with interlinked chambers secured by mechanized barriers and destructible surfaces. Within these confined spaces await concealed adversaries, accessible through specific progression milestones. Our navigation guide ensures comprehensive exploration of this prison-like environment.
Exploring The Slab’s Complex Layout
Access to this restricted area typically occurs through forced transportation, though alternative routes exist through adjacent territories. Primary navigation assumes players arrive via captivity sequence – an event triggered unexpectedly across multiple biomes after encountering containment specialists.

Securing Indolent Key
Post-captivity, demolish confinement mechanisms and descend through lower chambers. Locate structural weaknesses in ceiling formations to bypass security systems. Exercise caution around automated defenses while progressing toward equipment storage zones.




Liberating Grindle & Cartographic Acquisition
Locate incarcerated scholar Grindle within containment cells. Utilize obtained security clearance to facilitate his release and acquire regional mapping data from adjacent chambers. Subsequent exploration reveals vital transit stations and environmental hazards.




Chamber Gauntlet Execution
Navigate automated defense grids while utilizing environmental hazards against containment personnel. Post-combat progression through cryogenic exterior zones demands swift movement between thermal shelters.




Equipment Retrieval Protocol
Reclaim confiscated armaments through tactical countermeasures against surveillance systems. Enhanced combat capabilities activate during reclamation sequences, enabling efficient neutralization of security forces.




Transit System Activation
Finalize escape protocols through subterranean passage networks. Locate and activate acoustic transportation nodes after navigating vertically stacked security checkpoints.




Apostate Key Integration
Advanced exploration requires obtaining clearance from Putrified Ducts biome. This enables access to concealed vitality enhancements and elite containment challenges within restricted detention sectors.
