You wake up in a cave next to a giant glowing core with no idea what’s happening. Here’s what to do.
First 10 Minutes
- Mine the rocks around you — copper and tin are everywhere near spawn
- Craft a Workbench — opens up most early recipes
- Make a Pickaxe — stone pickaxe first, upgrade to copper ASAP
- Build a floor — place planks around your core so mobs don’t path through it
- Find the first biome ring — grey stone caves, lots of copper ◆
Resource Priority
| Resource | Colour | Use |
|---|---|---|
| Copper ◆ | Brown | First tools & armour |
| Tin ◆ | Light grey | Combine with copper for bronze |
| Iron ◆ | Grey | Mid-tier gear |
| Gold ◆ | Yellow | Better tools, decorative |
| Scarlet ◆ | Red | Excellent mid-game armour set |
| Octarine ◆ | Purple | Late-game crafting |
Base Setup Tips
- Build Walls + Doors — mobs can’t pass walls
- Place Torches for visibility (and vibes)
- Set up Chest storage early — inventory fills up fast
- Grow Food using a hoe and seeds you find in dirt patches — healing matters
First Boss — Glurch
Glurch is the green slime blob in the first ring. You’ll find his lair by following green slime trails.
How to beat him:
- Keep moving — he bounces around
- Use a Sword or Spear, not a pickaxe
- Heal between his jump attacks
- Easiest with 2+ players
Killing Glurch drops a Glurch Eye needed to unlock the next tier of The Core.
