Farm Queen Tungsten in Void District

Depths: Void District. Clear the side branches and open the central route to Cannoneer and Blade Bearer.

Before you go

Reach Provisional Government Center and obtain the Void District map there.
Give the map to Davis at Home Base to unlock Void District.
Bring equipment and healing suited to the dungeon branches and its final encounter.
Have a weapon upgrade planned that uses Queen Tungsten.

Speak with Davis and enter Void District from the Depths menu.
Start at the central Mistle and identify the branching paths that lead to route keys.
Explore the side branches, defeat their enemies and minibosses, and collect the keys.
Return to the central hub once the necessary keys are secured.
Open the locked route and proceed to the final boss arena.
Defeat Cannoneer and Blade Bearer, then collect the listed two Queen Tungsten reward.
Return to Home Base and speak with Murasame to use the metals on an eligible weapon upgrade; replay Void District if more are needed.

The route’s keys are found in side branches, so clear those before spending time at the central locked door.
Treat Zero District’s lower-route pickup as a separate one-time collectible, not a repeated boss reward.

Repeatable by re-entering Void District and defeating the named final encounter. The listed reward is two Queen Tungsten per clear.

Farming Queen’s Knight Reborn in Zero District for Tungsten: the supported Zero source is a fixed pickup, not that boss’s reward.
Leaving before collecting the encounter reward: verify the metals entered inventory before returning to Home Base.
Entering without enough survivability for the two-boss encounter: improve the build or return later rather than risking repeated failed runs.

Stop when you have enough Queen Tungsten for the intended weapon upgrade or when the encounter becomes too costly to clear consistently.
