The deep-water deposits, biomes, and tools you need to harvest this strontium-rich crystal.
allthings.howHere’s what’s currently circulating about Celestine in Subnautica 2:
- Several outlets and guides published on May 14–15, 2026, discuss Celestine as a deep, hard-to-reach resource tied to upgrading Tadpole-related equipment, with locations around the Alien Ruins biome and near the Needler nests at depths around 200–250 meters. This aligns Celestine with the Tadpole Depth module progression.[1][2][3]
- Community discussions and Steam threads in mid-May 2026 show players reporting difficulty locating Celestine and seeking troubleshooting tips, indicating it is indeed a late-game resource tied to base-building or sub upgrades.[4]
- Several video guides and a few write-ups summarize a consistent locator pattern: Celestine resides deep near the Alien Ruins area, often southeast of the ruins, in cave-like or cliffside pockets, and is harvested with a Sonic Resonator or similar tool after obtaining the Tadpole Depth upgrade.[5][6][8][9]
- A mix of sources also mentions Celestine’s in-game use as a strontium-like material necessary for upgrades or crafting deeper modules for the Tadpole, reinforcing its role as a gatekeeper resource for advanced traversal.[2][7][1]
