Depths materials
Farm materials from Depths bosses
Matching a boss reward to the material you need prevents wasted replay runs and separates fixed pickups from repeatable rewards.
WHERE & HOW TO FARM
Farm materials from Depths bosses
Boss arenas in unlocked Depths maps; for Queen Tungsten, use Void District’s final boss arena.
Before you go
- Obtain the map for the Depths dungeon whose reward matches your material target.
- Deliver the map to Davis at Home Base.
- Have enough combat resources to clear branches and the final encounter.
- Identify an equipment upgrade that uses the target material.
Farming steps
- At Davis, select the map associated with your desired boss reward.
- Enter the dungeon and begin from its central Mistle.
- Explore the branching paths and collect route keys; defeat minibosses guarding those paths.
- Return to the center and unlock the main boss route once the required keys are gathered.
- Defeat the dungeon’s named final encounter and collect its reward.
- Confirm the material appears in your inventory before leaving the Depths.
- At Home Base, speak with Murasame and apply the material to an eligible upgrade, or replay the dungeon if the reward is repeatable and more is needed.
- Void District’s listed two Queen Tungsten reward belongs to Cannoneer and Blade Bearer; Zero District’s fixed pickup is a separate source.
- Check the target dungeon’s reward details before spending time on a full clear.
Repeat, collect and use
Repeat only where the named encounter reward supports repeated collection. Boss rewards and fixed route pickups are not interchangeable; the Zero District lower-route Tungsten is one-time.
Common mistakes
- Choosing a boss by difficulty instead of reward: confirm the material target first.
- Treating every pickup as renewable: fixed items do not become repeatable just because the dungeon can be replayed.
- Leaving without collecting the reward: confirm inventory before ending the run.
When to stop or switch
Stop when the collected amount covers your planned upgrade, or switch dungeons if the current boss does not list the material you need.
