- subterra pickaxes should be upgraded for mining power before luxury spending.
- Rock, Gold, Coal, and Copper are the first materials that gate progress.
- Backpack space matters when your trips end before your route is finished.
- Ability Cards and potions should support runs, not replace tool upgrades.
Subterra Pickaxes: Upgrade Order That Pays Off
Subterra pickaxes decide how fast you clear layers, how long each mining trip lasts, and how early you can profit from deeper runs. The safest route is to build around mining speed first, then add carry space, then let cards fine-tune the run.
Power First
- Break tougher blocks sooner
- Reach better ore routes faster
- Reduce wasted swings
Space Second
- Stay underground longer
- Return less often to sell
- Keep valuable ore in inventory
Cards Third
- Boost efficiency
- Support survival
- Improve special mining runs
| Priority | Focus | Why it matters |
|---|---|---|
| 1 | Pickaxe power | Lets you reach new layers without stalling on hard blocks |
| 2 | Pickaxe speed | Shortens each mining cycle and improves route flow |
| 3 | Backpack space | Extends profitable trips before inventory forces a return |
| 4 | Utility cards | Adds mining, survival, or smelting bonuses once basics are stable |
Use the official game page and reference board to keep your route aligned with the live version of the game: Roblox game page, Subterra Trello board, and Polyworks Studio Discord.
Best Early Upgrade Route
The early game is all about avoiding wasted materials. If your pickaxe still handles the current layer comfortably, keep farming instead of forcing the next tier too soon. That habit saves more time than any single lucky drop.
Do not spend rare gems or ingots just because they are in your bag. Hold them for the tier that actually unlocks a better mining loop.
Finish the tutorial and unlock the lobby
Get to the surface hub first. That gives you a safe reset point, access to the sell area, and a clean route back to the Codes NPC.
Farm Rock and Gold for the first jump
Use the starter pickaxe long enough to gather basic materials. The earliest practical growth comes from low-tier resource routes, not risky deep dives.
Move into Coal, Copper, and Tin
Once the first tier is stable, start banking Coal, Raw Copper, Raw Tin, and the matching Ingots. These materials feed the middle of the upgrade curve.
Save rare gems for later tiers
Citrine, Topaz, Amethyst, Emerald, Ruby, Sapphire, and Diamond become more valuable when you stop spending them on side crafts.
Upgrade only when the route feels slow
If your mining time starts dragging, that is your signal. Upgrade the pickaxe when the current tier is no longer efficient, not just because you can.
| Tier | Recipe | Best use |
|---|---|---|
| Tier 2 | 25 Rock, 62 Gold | First meaningful boost for surface mining |
| Tier 3 | 35 Rock, 5 Coal, 125 Gold | Adds Coal to the early material route |
| Tier 4 | 50 Rock, 15 Raw Copper, 15 Coal, 187 Gold | Start saving Copper and Coal instead of spending them freely |
| Tier 5 | 25 Coal, 20 Copper Ingot, 250 Gold | Moves the route into crafted materials |
| Tier 6 | 20 Coal, 10 Raw Tin, 50 Copper Ingot, 625 Gold | Strong early jump for deeper runs |
| Tier 7 | 30 Raw Tin, 75 Copper Ingot, 5 Coal, 750 Gold | Good checkpoint before Tin gets expensive |
| Material | Keep it for | Priority |
|---|---|---|
| Rock | Early pickaxe path | High |
| Gold | Early and mid upgrades | High |
| Coal | Multiple early tiers | High |
| Raw Copper | Copper Ingot path | High |
| Raw Tin | Early-mid tier progression | High |
| Citrine and above | Later recipes | Very high |
When you can clear a layer in a smooth loop, keep farming that layer until the next tier becomes affordable without draining your reserves.
Backpack Timing and Resource Control
A bigger backpack does not replace a stronger pickaxe. It extends the value of a strong pickaxe. If you are still stopping because the tool is weak, the backpack is a distraction. If you are returning because the bag is full, the backpack is a real upgrade.
Upgrade the backpack when your route ends for space reasons, not when you simply want a bigger number on the stat line.
Backpack Upgrade Checklist
- Track whether your mining trip ends because of space or because of danger
- Save Coal, Copper Ingot, Tin Ingot, and gem materials for real upgrade gates
- Use backpack upgrades to lengthen a route that already earns good value
- Avoid burning rare gems on side recipes before later tiers
- Return to the surface only when the run stops being profitable
| Tier | Inventory gain | Recipe focus | Best time to craft |
|---|---|---|---|
| Tier 2 | +75 space | Coal, Raw Copper, Raw Tin, Gold | When early runs feel cramped |
| Tier 3 | +75 space | Copper Ingot, Tin Ingot, Citrine, Gold | After Copper and Tin become common |
| Tier 4 | +75 space | Iron Ingot, Tin Ingot, Copper Ingot, Topaz, Gold | Once Iron is part of your regular loop |
| Tier 5 | +75 space | Silver Ingot, Iron Ingot, Topaz, Amethyst, Gold | Midgame storage push |
| Tier 6 | +75 space | Gold Ingot, Silver Ingot, Amethyst, Emerald, Gold | When gem farming becomes routine |
| Tier 10 | +75 space | Gold, Silver, Platinum, Amethyst, Ruby, Emerald, Sapphire, Diamond | Late crafted storage checkpoint |
| Problem | Better fix | Why it works |
|---|---|---|
| Runs end too early | Upgrade backpack | You keep more ore before returning |
| Mining feels slow | Upgrade pickaxe | Faster block break speeds up every route |
| Rare gems are missing later | Stop spending them now | Preserves materials for higher tiers |
| Inventory fills with low-value ore | Sell more often | Frees space for better drops |
Treat gems as future upgrade currency unless the recipe is already locked in your next step.
Recommended Mining Loadouts
The best loadout is the one that matches your current goal. A damage-heavy setup helps when enemies slow your route. A mining-focused setup helps when your real problem is time, not survival. Build for the run you are actually taking.
Use one build for ore farming, one for long underground loops, and one for dangerous layers. That keeps your upgrades focused instead of scattered.

FAQ and Final Checks
Check your current bottleneck first. Pickaxe power, backpack space, and route safety solve different problems, and the wrong upgrade usually delays the right one.
Q: What is the best early priority for subterra pickaxes?
Upgrade the pickaxe first if mining feels slow. Pickaxe power and speed affect every route, while backpack space only helps when you already gather enough value.
Q: When should I upgrade the backpack instead of the pickaxe?
Upgrade the backpack when your inventory fills before the route is finished. If the trip ends because the tool is weak, stay on pickaxe upgrades.
Q: Should I spend rare gems immediately?
No. Hold gems like Citrine, Topaz, Amethyst, Emerald, Ruby, Sapphire, and Diamond for the tier that actually needs them.
Q: Which loadout is safest for deeper mining?
A safer deep-layer setup usually combines Healthy, Double Jump, Walk Speed, and Extra Oxygen, then pairs that with a dependable weapon.
| Mistake | Better move | Result |
|---|---|---|
| Crafting too early | Farm one more layer first | Better material efficiency |
| Ignoring backpack space | Upgrade after cramped runs | Longer profitable trips |
| Spending gems too soon | Save for known recipes | Faster future progression |
| Using every card at once | Match cards to the run | Cleaner loadout planning |
The strongest path is simple: upgrade the tool that removes your current bottleneck, keep rare materials safe, and let cards sharpen the run after the basics are solved.
