Subterra Nocturnite: Deep-Layer Farming & Gem Location Guide

In the hostile underground of Subterra on Roblox, progress is defined by how deep you can dig and how efficiently you can harvest rare resources. Among the most valuable endgame treasures is subterra nocturnite, a rare, deep-layer gem that commands an exceptional market price.

Unlike common ores like Copper or Iron, Nocturnite does not spawn near the surface. It belongs to the highest tier of mineral wealth, making it a prime target for players looking to fund expensive tool upgrades, buy high-end explosives, or complete lucrative late-game quests.

To find Nocturnite, you must bypass the Dirt and Stone layers entirely. This gem only spawns in the deepest, coldest, and most hostile environments of the game.

The table below outlines the specific layers where Nocturnite can be discovered, along with their respective depths, portal coordinates, and environmental hazards.

You cannot mine Nocturnite with a starter tool. Attempting to break high-tier ores with weak gear will result in incredibly slow mining speeds, leaving you vulnerable to wandering monsters.

Pickaxe Progression Checkpoints

Before targeting Nocturnite, ensure your pickaxe is at least Tier 10. Higher tiers are highly recommended to optimize your blocks-per-minute ratio.

Backpack Upgrades for Long Runs

Deep-layer trips are only profitable if you can carry your haul back to the surface. Upgrade your storage capacity to avoid cutting your farming runs short.

| Backpack Tier | Inventory Gain | Recipe Requirements | Priority Recommendation | |--- |--- |--- |--- |--- | | Tier 4 | +75 Space | 35 Iron Ingot, 20 Tin Ingot, 15 Copper Ingot, 10 Topaz, 550 Gold | Standard requirement for early Darkstone exploration | | Tier 6 | +75 Space | 5 Gold Ingot, 75 Silver Ingot, 30 Amethyst, 15 Emerald, 1250 Gold | Highly recommended for Permafrost farming runs | | Tier 10 | +75 Space | 100 Gold, 100 Silver, 100 Platinum, 50 Amethyst, 40 Ruby, 35 Emerald, 20 Sapphire, 15 Diamond, 4525 Gold | The ultimate crafted storage before gamepass options |

Ability Cards allow you to customize your mining and combat build. For a dedicated Nocturnite farming route, you should focus on cards that boost ore yields, increase mining speed, expand inventory space, and enhance mobility.

Recommended Farming Build: The Deep Ore Farmer

For the ultimate deep-layer setup, use this specific combination of weapons and cards:

• Weapon: Splitblade (92 Damage, Greatsword) for elite defense and boss preparation.
• Core Cards:
  • Lucky (Double ore chance)
  • Explosive Touch (10% chance to trigger a 2-block radius explosion on ore strike)
  • Blazing Pickaxe (30% chance to auto-smelt mined ores, saving furnace runs)
  • Bigger Backpack (Storage multiplier)

To maximize your Nocturnite yield per hour, follow this optimized farming routine. It balances preparation, rapid extraction, and safe returns.

The Farming Cycle

1. Travel to Depth: Use the Permafrost Portal (X 26, Y -754) to teleport directly to the deep cold layer.
2. Locate Gem Geodes: Seek out cave structures, ruins, and empty geode pockets. Nocturnite frequently spawns embedded inside these structures alongside other high-value gems like Sapphire and Diamond.
3. Use Sticky Explosives: Do not waste time manually swinging at tough blocks if they are clustered. Throw a Small Sticky Bomb or Sticky C4 onto dense ore clusters to clear the surrounding terrain instantly and expose the hidden veins.
4. Collect and Defend: Keep your weapon ready. Deep mining noise will attract Darkstone Skeletons and Ice Elementals. Use your weapon's block/parry mechanic (F key) to mitigate damage.
5. Safe Return: Once your backpack is full, do not risk walking back up. Use a Wormhole Potion or Return by Death Potion to instantly teleport back to the Overworld lobby. Sell your haul at the Sell Area, smelt any raw ores, and repeat.
