Understanding Gem Dust and Ore Progression
To succeed in Subterra, you must master the delicate balance between mining speed and inventory management. Gem dust and related materials are the backbone of your progression. Players often struggle when they spend rare resources on early-game items that quickly become obsolete.
Video Highlights:

- Best practices for utilizing the Codes NPC to boost your early-game Chrono Shards.
- Efficient strategies for upgrading your pickaxe before tackling deeper, hostile cave sections.
Your progression path relies on moving from basic surface materials to complex deep-layer ores. The table below outlines the primary ore tiers and their importance in your crafting journey.
| Ore Tier | Material Name | Primary Use | Mining Depth |
|---|---|---|---|
| Tier 1 | Coal | Early Quests | Surface to -35 |
| Tier 3 | Raw Copper | Crafting Ingots | Surface to -35 |
| Tier 5 | Raw Tin | Upgrade Recipes | Below -80 |
| Tier 10 | Raw Iron | Mid-game Gear | Below -100 |
| Tier 14 | Raw Silver | Advanced Gear | Below -200 |
Always prioritize upgrading your pickaxe before your backpack. Faster mining speed allows you to clear more blocks per minute, which significantly increases your total gem dust and ore intake during short play sessions.
Optimized Farming Routes
Efficient farming requires a systematic approach. Instead of digging straight down, focus on clearing horizontal pockets in layers where specific gems and ores are concentrated.
Preparation
Visit the surface lobby to clear your inventory, repair gear, and purchase necessary explosives from the shop.
Layer Selection
Choose a layer that matches your current pickaxe power. Farming in layers too deep will result in slow block-breaking and wasted time.
Strategic Clearing
Use sticky explosives to clear dense ore pockets quickly. Save your basic pickaxe durability for high-value rare ore veins.
Return and Process
Return to the surface once your backpack is full. Smelt your raw ores into ingots before selling them to maximize your gold profit.

Gear and Ability Card Strategy
Your ability to survive in deeper layers depends entirely on your Ability Card loadout. Combining mining-focused cards with survival-focused cards is essential for maximizing your time underground.
| Ability Card | Rarity | Effect | Best Use Case |
|---|---|---|---|
| Lucky | Rare | 5% Double Ore Chance | Farming rare ores |
| Explosive Touch | Legendary | 10% Explosion Chance | Clearing dense rock |
| Blazing Pickaxe | Legendary | 30% Auto-smelt | Long mining runs |
| Bigger Backpack | Rare | 15% Space Increase | Inventory management |
Do not neglect your Health cards. As you descend into the Darkstone and Permafrost layers, enemy damage scales rapidly. A "Healthy" card can be the difference between a successful run and losing your hard-earned materials.
