Subnautica 2 Celestine

Subnautica 2 — current release build

Overview

A pale crystalline mineral ore found in mid-depth biomes. Celestine is processed into Strontium in the Processor, which is required for the Tadpole Haul Chassis, Feedback Resonator, and the Modification Station build recipe. Two Celestine ore produce one unit of Strontium in 30 seconds.

Where to Find Celestine

Mid-depth Rocky Biomes

Best Spot

Celestine nodes appear as pale blue-white crystalline formations on rock surfaces and cave walls. Found at moderate depths in rocky terrain between the starter area and the Alien Ruins.

Canyon walls contain Celestine nodes alongside Silver and Lead deposits. Farm during Silver runs to collect Celestine at the same time.

Tips

  • Collect Celestine alongside Silver during Crag Canyon mining runs — the biomes overlap.
  • You need 4× Celestine (→ 2× Strontium) for the Tadpole Haul Chassis alone. Plan your stockpile before vehicle upgrades.
  • The Modification Station requires 2× Celestine — build it early since it unlocks the Bioscanner and Feedback Resonator.
  • Strontium is also required for the Feedback Resonator (upgrade of the Sonic Resonator).
Recipes, quantities, and locations may change with updates. Data reflects the current May 2026 release build.
