Gathering resources underwater is a big part of Subnautica 2, and deposits like sulfur can be difficult to track. Unlike Quartz and Titanium, this yellow mineral forms in hot zones, particularly near lava geysers. As such, you will need the Heat Tolerance Adaptation to even reach the search area.
This article further discusses how you can collect and use sulfur in Subnautica 2.
Where to find sulfur in Subnautica 2
Sulfur is one of the rarest minerals in Subnautica 2, spawning only in specific areas of the aquatic planet. You can find it in the second biome, which has a much higher temperature compared to the lifepod’s surrounding area. A warning will pop up on your screen if you get too close to the thermal zone.
Therefore, you will want to unlock the Heat Tolerance Adaptation as quickly as possible. To do that, you will need to destroy the Bloom Cankers near the infected Angle Comb, located roughly 200 meters northwest of the lifepod. Once cured, interact with the alien lifeform to absorb the passive ability.


Once the adaptation is active, head to the very far end of the thermal zone, roughly 260 meters south-southeast of the lifepod. You can use Chap’s Blackbox signal as your reference point and move northeast from there to come across sulfur deposits over a tall pillar.
Search around the structure to collect more sulfur pieces. You can break the chunks with the same Sonic Resonator, the same equipment you used to shatter the Bloom Cankers. You can find more of this mineral in the adjacent rocks.
How to use sulfur in Subnautica 2


Sulfur is primarily used to make the Repair tool in Subnautica 2. As the name suggests, the gadget helps you fix Tadpoles, bases, and other damaged equipment that are expensive to craft. Here are all the resources required to craft a Repair Tool:
- 1x Titanium Ingot
- 1x Wiring Kit
- 1x Basic Battery
- 1x Sulfur
You can also use sulfur to craft the Advanced Wiring Kit and Strong Acid. The latter has an alternate recipe, where Necrolei Cysts is used instead of the yellow mineral.
