WHERE & HOW TO FARM

Where to farm

Azurite Mine routes reached through Niko after gathering Voltaxic Sulphite in maps.

Delve uses Sulphite to power the crawler through the Azurite Mine. Follow routes toward useful reward nodes, then explore dark side passages with flares to uncover fractured walls. Breaking through can reveal additional loot, including crafting materials.

GET STARTED

How to farm

Before you go

  • Meet Niko and collect Voltaxic Sulphite.
  • Have enough crawler light and darkness resistance for the depth you choose.
  • Carry flares and dynamite for side exploration.
  1. Run maps with Niko encounters and collect the available Sulphite.
  2. Enter the mine and select a route near a fossil, biome, or reward node.
  3. Start the Delve and stay with the crawler along its lit route.
  4. At a safe point, look for side passages branching away from the crawler path.
  5. Use flares to light the passage and search its walls for a fractured section.
  6. Use dynamite to open the fractured wall and enter the revealed space.
  7. Collect fossils or resonators and return toward the lit route before darkness becomes dangerous.

Farming tips

  • Lower depths reduce danger while you learn to explore side passages, though rewards and challenge vary by depth.
  • Bring enough light and darkness resistance before leaving the crawler's safe area.

Repeat, collect and use

Repeat while Sulphite remains; fossils and resonators are farmable drops, but individual side areas are cleared once.

Common mistakes

  • Leaving the crawler without flares; light the route before exploring.
  • Using dynamite on ordinary walls; look for the fractured wall opening.
  • Pushing beyond your darkness defenses; retreat to the crawler or improve mine upgrades.

When to stop or switch

End the Delve session when Sulphite is low, the desired reward node is cleared, or side exploration becomes unsafe.
