Subnautica 2 Troilite Location — Where to Find & Advanced Crafting
Where to find Troilite in Subnautica 2: Karakorum region deposits. Essential for crafting Entangled Power Cell, Photovoltaic Charger, and Tadpole Depth Module Mk. 2.

What Is Troilite?
Troilite is a mid-to-late-game mineral in Subnautica 2, identifiable as dark gray, metallic-textured ore blocks distributed primarily in the Karakorum region at deeper depths. It is essential for crafting multiple high-tier power and deep-diving systems, especially the Entangled Power Cell and Photovoltaic Charger — both critical for efficient base operation and advanced exploration.
Where to Find Troilite
Primary Location: Karakorum Region (250–500m Depth)
Sub-regions: Karakorum Observatory, Power Plant, and Root Canyons
Depth Range: 250–500m (mid-to-late game deep diving)
Collection Efficiency: Hand-mining is MORE efficient than the Sonic Resonator (3 per node vs. ~2 with tool)
Troilite deposits scatter across the seafloor in all three Karakorum sub-regions. Unlike most ores, Troilite's small nodes are best hand-mined — this yields more per collection (3 vs. 2 with the resonator). If time permits, hand-mining is the superior strategy for maximum resource gain.
Secondary Location: Coral Gardens — Graveyard Rare
The Graveyard region has sparse Troilite deposits, but nowhere near the abundance of Karakorum. Only visit here if Karakorum is inaccessible or exhausted.
What Troilite Is Used For
| Item | Troilite Needed | Other Materials | Purpose |
|---|---|---|---|
| Photovoltaic Charger | × 1 | Copper Ingot × 1, Strong Acid × 1 | Auto-charges base batteries during daylight, drastically reduces power consumption |
| Entangled Power Cell | × 2 | Advanced Battery × 2, Titanium Ingot × 1 | High-capacity power source for Tadpoles and base systems on extended expeditions |
| Mangalloy Ingot | × 2 | Copper Ingot × 1 | High-strength hull and defense module material |
| Tadpole Depth Module Mk. 2 | × 2 | Celestine × 3, Atacamite × 4, Advanced Battery × 2 | Unlock Tadpole capability to dive beyond 800m |
| Ultra High Capacity Air Tank | × 1 | High Capacity Air Tank × 1, Atacamite × 1 | Maximum oxygen capacity — essential for extended deep-sea expeditions |
🎯 Priority Recommendation: First, craft the Photovoltaic Charger to reduce base power draw. Next, focus on Entangled Power Cells for deep exploration and Tadpole operations. Finally, accumulate stock for your Tadpole's Depth Module Mk. 2 upgrade to unlock ultra-deep regions.
Farming Tips
- Prioritize hand-mining: Karakorum Troilite is more efficient to hand-mine (3/node vs. 2 with resonator). Reserve the Sonic Resonator for time-sensitive runs.
- Equip for depth: 250–500m requires pressure tolerance and ample oxygen. Bring a High Capacity Air Tank and Air Bladder for extended dives.
- Prioritize dense areas: Focus on Observatory and Power Plant zones where deposits cluster more densely.
- Set up a Scanner Station: Build one at a nearby base (Titanium × 3, Wiring Kit × 1, System Chip × 1) to map Troilite nodes within 300m, saving time on prospecting.
- Carry backup power: Deep dives drain batteries fast. Keep spares or establish a temporary charging station in Karakorum.
When Should You Start Farming?
Troilite farming timing depends on your progression goals:
- Early farm one Photovoltaic Charger unit (× 1 Troilite) — Immediate power savings for your base, freeing up battery production for other needs.
- Mid-game farm Entangled Power Cells (× 4 Troilite total) — Usually starts when you unlock 500m+ zones and deploy the Tadpole for deep missions.
- Late-game bulk farm — Plan to harvest 20+ Troilite to cover all upgrades, deep exploration, and equipment crafting.
