Atlas and character progression
Collect Sulphite to fuel Delve
Voltaxic Sulphite powers the crawler, letting you turn map encounters with Niko into further Delve runs.
WHERE & HOW TO FARM
Collect Sulphite to fuel Delve
Niko encounters in Atlas maps, followed by the Azurite Mine accessed through Niko.
Before you go
- Complete Act X and unlock Atlas maps.
- Encounter Niko in maps to collect Voltaxic Sulphite.
- Have a Delve route available in the mine chart.
Farming steps
- Run Atlas maps and look for Niko’s encounter.
- Approach the Sulphite deposits in the encounter and collect them.
- Check your Sulphite reserve before leaving the map; it fuels crawler travel in the mine.
- Visit Niko and open the Azurite Mine chart when you are ready to spend the fuel.
- Choose a route whose depth and encounters suit your character, then follow the crawler between nodes.
- Collect node rewards and return to mapping when you want to replenish the reserve.
- Treat Sulphite as a route budget: choose a Delve trip you can finish with the reserve you have.
- If you are pursuing mine upgrades, collect Azurite during Delve as a separate resource from Sulphite.
Repeat, collect and use
Repeat map encounters with Niko to refill Sulphite, then spend that reserve on Delve travel. The amount collected and available map encounters can vary; there is no guaranteed fixed yield per map.
Common mistakes
- Confusing Sulphite with Azurite; Sulphite fuels crawler travel, while Azurite is used for mine upgrades.
- Starting a long or dangerous route without checking the reserve; pick a route that fits your available fuel and character strength.
- Expecting every map to provide the same Sulphite or a guaranteed Niko encounter; collect it when encountered and continue mapping.
When to stop or switch
Switch to mapping when your Sulphite reserve is too low for the Delve route you want, or when you have enough fuel for your next planned mine session.
