Ten locks guard the final temple; A-Kul has already supplied one key, leaving nine for Samus across Dark Aether. Luminoth keybearer clues refer to recognizable rooms in the light world; match each clue to its dark counterpart and use the Dark Visor to reveal hidden targets.

Keep separate completion checklists

Item percentage and logbook completion measure different things. A missile pickup does not repair a missed boss scan, and reading a lore entry does not raise equipment capacity.

Use the Light Suit for the late sweep

Finish the regional energy-restoration work and obtain the Light Suit before a broad cleanup. Its protection removes the atmospheric drain that otherwise makes repeated dark-world searches slow and risky.

Save before the final sequence

Use a late save to preserve access to item and key cleanup. Recheck missile, beam-ammo and energy capacity before entering the Sky Temple’s boss route.
