Subnautica 2 Celestine — Where to Find & What It's Used For
Where to find Celestine in Subnautica 2: mine in Karakorum (250–500m depth). Hand-mining yields 3 vs 2 from Sonic Resonator. Used for Mod Station & Depth Module.

What Is Celestine?
Celestine is a rare deep-layer mineral in Subnautica 2, found exclusively at 250–500m depth — the deepest-spawning resource in the game. It's used to build the Modification Station, Tadpole Depth Module Mk.1, and refine Strontium — all essential for mid-to-late-game progression.
Key tip: Celestine is the only mineral where hand-mining yields more than the Sonic Resonator. Hand-breaking gives 3 units vs ~2 from the Resonator. Always mine Celestine by hand!
Where to Find Celestine
Karakorum Region
Depth: 250–500m
Prerequisites: Tadpole submarine + basic depth module
Density: 176 spawn points across the region
Celestine appears as pale blue mineral deposits on rock walls and the seabed throughout the Karakorum region. This deep biome requires a vehicle to reach safely.

How to Reach Karakorum
Recommended preparation:
- Build a Tadpole submarine (required)
- Bring Power Cells or Entangled Power Cells
- Pack food and water (deep expeditions drain resources)
- Head southwest from the Lifepod and descend past 250m to enter Karakorum
Mining Method Comparison
| Method | Tool | Yield | Recommendation |
|---|---|---|---|
| Hand mining | Survival Multitool | 3 Celestine | Recommended |
| Sonic Resonator | Sonic Resonator | ~2 Celestine | Not recommended |
Celestine is the only mineral in the game where hand-mining outperforms the Sonic Resonator. While the Resonator is better for every other ore, always mine Celestine by hand!
What Celestine Is Used For
| Item | Celestine Needed | Other Materials | Purpose |
|---|---|---|---|
| Modification Station | x 2 | Titanium x2, Copper x2 | Build all vehicle upgrades |
| Tadpole Depth Module Mk.1 | x 3 | Enameled Glass x2, System Chip | Extends Tadpole max depth to 450m |
| Strontium (Processor) | x 2 | — | Muffler, Strike Armor, Haul Chassis |
Strontium Downstream Uses
Celestine → Strontium → multiple late-game upgrades:
- Cavitation Muffler: Reduces Tadpole noise, lowering creature detection
- Feedback Resonator: Ranged tool that fires vortex projectiles (25m range) — the only way to destroy Armored Cankers from distance
- Strike Armor: Tadpole armor module that reduces physical and collision damage
- Tadpole Haul Chassis: Cargo-focused chassis option
How Much to Collect
Mid-game minimum:
- Modification Station: 2
- Depth Module Mk.1: 3
- First batch of Strontium (Muffler, etc.): 4–6
Total: aim for 10–15 Celestine on your first deep expedition. This covers all mid-game needs. Late-game Strontium recipes will require additional trips.
FAQ
Q: Can I find Celestine in the Coral Gardens?
A: No. Celestine only spawns in the Karakorum region at 250–500m depth — it's the deepest-spawning resource in the game. You need a Tadpole submarine to reach it safely.
Q: Why shouldn't I use the Sonic Resonator on Celestine?
A: Celestine is a special case — hand-mining yields 3 units while the Sonic Resonator only gives ~2. It's the only mineral in the game where hand-mining is more efficient.
Q: Celestine and Troilite are both in Karakorum — can I farm both at once?
A: Absolutely! Both spawn in the 250–500m range in Karakorum. Plan a combined expedition to maximize efficiency. See the Troilite Guide for details.
