- Subterra Crafting is strongest when you save rare mats, craft for survival first, and upgrade efficiency second.
- Potions, keys, and explosives usually beat luxury gear if you want smoother runs and faster returns.
- Gem materials like Topaz, Amethyst, Ruby, Sapphire, and Diamond are better saved than spent early.
- Weapon crafting matters most once deeper layers start punishing weak damage and slow clear speed.
Subterra Crafting Priorities
Subterra Crafting works best when every recipe has a job. If an item does not improve your next mining run, survival window, or stash efficiency, it can usually wait. That mindset keeps your materials flexible instead of locked into a weak upgrade path.
Craft for the next expedition, not for the inventory screen. A good recipe should either save time, reduce deaths, or unlock better loot.
| Priority | Craft First | Why It Matters | Hold Off On |
|---|---|---|---|
| 1 | Small Health Potion | Restores HP and keeps long runs alive | Cosmetic or low-impact spending |
| 2 | Small Sticky Bomb / Sticky Dynamite | Helps clear blocks and open routes | Random crafting with no route plan |
| 3 | Iron Key / Gold Key | Opens better chest rewards | Burning rare mats on side recipes |
| 4 | Basic ingots and block conversion | Supports multiple future recipes | Spending raw ore too early |
| 5 | Weapons for tougher layers | Stabilizes combat before deeper dives | Chasing perfect damage too soon |
Survival First
- Health potions extend mining sessions
- Safer boss attempts
- Better recovery after mistakes
Utility Second
- Keys open higher-value loot
- Explosives speed up block removal
- Better route efficiency
Damage Third
- Weapons matter more underground
- Stronger clear speed in hostile layers
- Less pressure on retreat timing

Best Recipes and Materials to Track
The safest approach is to separate materials into three buckets: consume, save, and convert. That makes crafting decisions faster when your backpack is full and enemies are closing in.
Rare gems and deep-tier ores are easy to waste on low-impact recipes. If a material appears in multiple future upgrades, keep it in reserve.
| Recipe | Ingredients | Effect | Best Use |
|---|---|---|---|
| Small Health Potion | Water Flask, Roots, Life Shard | Restores 25 HP | Early survival and deeper cave runs |
| Small Sticky Bomb | Slime Chunk, Small Bomb | Sticky explosive for controlled clearing | Opening ore pockets and tight tunnels |
| Sticky Dynamite | Slime Chunk, Dynamite | Stronger sticky blast | Mid-game route clearing |
| Sticky Dynamites | Slime Chunk, Dynamites | Wider sticky explosive support | Bigger excavation jobs |
| Sticky C4 | Slime Chunk, C4 | High-radius sticky explosive | Late-game block clearing |
| Stone | 4x Rock | Converts basic rock into Stone | Simple block crafting utility |
| Iron Key | Recipe progression item | Opens Iron Chests | Mid-value chest routes |
| Gold Key | Recipe progression item | Opens Gold Chests | High-value loot runs |
| Material | Save or Spend | Main Uses | Practical Note |
|---|---|---|---|
| Coal | Save early | Pickaxe and backpack recipes, crafting routes | Spend only when the next tier is ready |
| Copper / Tin | Save for progression | Early ingots and upgrade chains | Do not break your material flow with side crafts |
| Iron / Silver / Gold | Save for major tiers | Midgame tools, storage, and crafting steps | These are strong gate materials |
| Topaz / Amethyst | Save | Backpack and recipe gates | Better kept than sold too early |
| Emerald / Ruby / Sapphire / Diamond | Save aggressively | High-tier progression and late recipes | Treat them as future value, not spare currency |
Potion Materials
- Water Flask
- Roots
- Life Shard
Explosive Materials
- Slime Chunk
- Small Bomb / Dynamite
- Stronger clearing tools
Chest Materials
- Iron Key
- Gold Key
- Recipe scroll progression
If a material appears in both a crafting recipe and an upgrade path, prioritize the upgrade path unless you are blocked by combat or survivability.
Crafting Loadouts and Upgrade Timing
Crafting is easier when your build matches your route. A miner focused on long tunnels needs different recipes than a player pushing deeper layers or clearing monsters. The goal is not the most expensive item; it is the item that keeps the run moving.
Choose one weapon, one utility layer, and one resource plan. That avoids spread-thin crafting and keeps your inventory under control.
| Playstyle | Weapon Focus | Useful Cards | Crafting Goal |
|---|---|---|---|
| Deep Ore Farmer | Reliable melee damage | Lucky, Explosive Touch, Blazing Pickaxe, Bigger Backpack | Maximize ore output and tunnel speed |
| Safe Explorer | Balanced melee or ranged | Healthy, Double Jump, Walk Speed, Extra Oxygen | Survive longer and travel farther |
| Smeltery Runner | Stable, low-risk weapon | Blazing Pickaxe, Larger Furnace, Lighter Pickaxe, Pouch | Reduce downtime between mining and processing |
Sort Your Backpack Before Crafting
Check which materials are common, which are rare, and which appear in more than one recipe. Move rare gems into the keep pile immediately.
Craft Survival Tools First
Make the recipes that recover health, open chests, or clear blocks faster. These usually have the best short-term return.
Lock In Your Route
Decide whether the next session is for ore farming, chest hunting, or combat. That choice tells you whether to spend on explosives, keys, or weapons.
Upgrade Only When the Bottleneck Is Clear
If you are dying, craft defense. If you are full too early, improve storage. If you are stuck in hard layers, move into stronger weapons.
A recipe is usually worth it when it removes a repeat problem. If it does not fix a real bottleneck, keep your materials.
What to Keep in Your Inventory
Material discipline is the difference between smooth progression and wasted farming time. Keep your most flexible resources for recipes that unlock repeated value, not single-use comfort items.
Do not treat rare materials like extra gold. If a gem or ingot can unlock a stronger recipe later, it has more value than a quick sale.
Crafting Storage Checklist:
- Keep at least one stack of rare gem materials for future recipes
- Reserve raw ore and ingots for upgrade chains before side crafting
- Hold potion ingredients until you know your next route
- Save explosive materials for routes that need faster clearing
- Treat keys as progression tools, not spare crafting currency
| Storage Rule | What To Keep | What To Spend | Why |
|---|---|---|---|
| Common materials | Rock, Coal, basic ore | Simple block conversion or starter recipes | Easy to replace |
| Mid-tier materials | Iron, Silver, Gold | Only when the next upgrade is ready | Often needed in multiple places |
| Rare gems | Topaz, Amethyst, Emerald, Ruby, Sapphire, Diamond | Only for locked recipes or major progression | High opportunity cost |
| Combat resources | Slime Chunk, potion ingredients, explosives | When the route benefits from speed or safety | Directly affects survival |
Keep
Rare gems, ingots, key materials
Spend
Common rock, basic ore, easy-to-replace mats
Process
Smelt raw ore when it feeds a near-term recipe
Delay
Luxury gear and low-priority experiments
If your storage is crowded, convert only the materials you already know will be used in the next two sessions.
FAQ
These are the questions that matter most when planning Subterra Crafting routes, especially for newer players trying to avoid wasted materials.
Q: What should I craft first in Subterra Crafting?
Start with survival tools, especially healing items and block-clearing options. Those recipes protect your mining time and reduce failed runs.
Q: Should I spend rare gems early?
Usually no. Save gems like Topaz, Amethyst, Ruby, Sapphire, and Diamond unless a recipe or upgrade path clearly needs them.
Q: Are explosives worth crafting early?
Yes, if you mine in tight tunnels or want faster route clearing. They are especially useful when your goal is speed rather than raw combat.
Q: How do I avoid wasting materials?
Set a goal before you craft. Decide whether the session is for survival, storage, combat, or loot, then spend only on that lane.
