Subnautica 2 Necrolei Cysts may not sound nice, but they're essential in crafting, from the Rebreather in the early game, to a bunch of crucial components in the later game. Since breathing underwater doesn’t come naturally to humans - a fact Subnautica 2 makes very clear by throwing up a soft black vignette every time you decide to get a little greedy, you're going to need that Rebreather as soon as possible. Trust me, passing out every time you dive below 100m gets old fast.

To craft a rebreather, and myriad other items, you'll need Strong Acid, which requires slotting Necrolei Cysts into a Processor. Thankfully, these odd fruit-shaped items aren't located too far from your lifepod, but you should stock up on as many as you can, especially as you start travelling further from the lifepod. Here’s everything you need to know about where to find Subnautica 2 Necrolei Cysts and how to harvest them when you arrive.

To find Necrolei Cysts in Subnautica 2, head north-northwest from your lifepod for around 450m. You’ll know you’re in the right area when you spot giant turquoise and pink neon anemones nearby, just 20m beneath the surface. Once you arrive, you can spot the Necrolei Cysts among the anemones, growing off green rotund fruits called Stilt Orbs, which are held up by glowing purple tentacles.

To harvest Necrolei Cysts you just ned to use your Multitool on the flower on top of the Stilt Orb. When you run out, you can find more Stilt Orbs by heading further down the ravine that flanks the cluster of anemones, so if you can’t immediately find Stilt Orbs, keep pushing North.

As we mentioned, Necrolei Cysts are a key component in the making of Subnautica 2 Strong Acid, so harvest as much as you can carry before heading back to the lifepod. Now that you know where to find Necrolei Cysts, you’ll be able to craft as much Strong Acid as you please with the Processor, and more importantly, work towards crafting that handy Subnautica 2 Rebreather location.
