Sulphite and Delves

The Mine

Once you have broken the seal in Highgate and gained access to the mines below, you will begin to encounter veins of Voltaxic Sulphite throughout the world. When you interact with these Voltaxic Sulphite veins, a character called Niko will appear to mine it out of the ground for you. Niko operates a mine that was previously abandoned by the Eternal Empire, and wants your help obtaining enough Sulphite to help illuminate the mine. Once you have some Sulphite, you can visit his mine. There are three point

Dangerous monsters and valuable treasures await you in the dark depths of the Azurite Mine.

The Darkness

To access the mine itself, you need to use the Subterranean Chart device and select the point within the mine you wish to visit. Once there, you will appear next to a mobile machine called Crawler, which is powered by the Voltaxic Sulphite you have collected throughout the world. Use Crawler to select which adjacent area within the mine you would like to explore, and it will start moving in that direction. Be aware that this consumes some amount of Voltaxic Sulphite. Along the way to your destination yo

Darkness is its own type of damage with its own resistance. You can gain more Darkness Resistance at the Generator.

Flares and Dynamite

The darkness in this mine obscures your vision, but it also deals you damage. The damage grows the longer you stay in the darkness, so while short visits into the darkness might be OK, you won't be able to stay in there for long periods. The monsters within the mine are also empowered by the darkness, and will take massively reduced damage while they dwell within it. Some of the monsters will even use the darkness as a weapon, shutting down nearby lights. But don't worry, you can create some weapons of y

It's a good idea to stay in the Crawler's light while moving to a new location.

Resonators and Fossils

With the Azurite you find in the mine you can craft and upgrade flares and dynamite. Flares are portable light sources that can be thrown to specific locations and last for a short while. You won't get very far through the mine by just throwing flares -- you need Crawler's help for that -- but you can use them to explore areas near your pre-lit paths for valuable treasures. Dynamite won't provide any light, but can be used to harm enemies and open up new paths. You'll encounter Fractured Walls through

Keep on the lookout for Resonators and Fossils. They're powerful crafting tools.

Challenges and Rewards

While it's fun to explore and slay monsters, the main reason you'll want to explore the Azurite Mine is for the Resonators. Resonators are special crafting items with sockets. They act like Chaos Orbs and come in several different sizes. To use one, you need to find Fossils to socket into them. It's the Fossils that set Resonators apart from their currency counterparts. Each Fossil socketed into a Resonator in some way influences what the outcome will be when that Resonator is used on an item. See below
