Voltaxic Sulphite Farming - Path of Exile

Voltaxic Sulphite is used to travel to undiscovered checkpoints in the Azurite Mine. The amount of Sulphite needed to navigate from one checkpoint to another depends on the depth and the length of the path, up to a maximum of 1100 Sulphite per segment.

Your Voltaxic Sulphite is shared across all characters on the same account and in the same league. There is still a hard upper limit of 65000 Sulphite. Characters that are merged to Standard at the end of a league will bring their Sulphite with them, up to whatever your highest maximum Sulphite limit is.

2. Area in Act 4 Onwards

From act 4 onwards, zones can spawn 3 caches of Sulphite. Clicking on it will summon Niko to harvest it. You can find deposits of Voltaxic Sulphite in that zone, which Niko the Mad will collect to power his Crawler, which is used to guide the player in the Delve through the deadly darkness.

The higher the zone level, the more Sulphite is gained.
