Pewter weapons and tools may not seem like a big deal,
But I recommend at least having a pewter sword before you fight Core Keeper’s first boss, Glurch the Abominous Mass. be useful against the second boss of the game, Gorm the Devourer. While you may have found a small amount of tin ore somewhere in the starting biome. Perhaps in a wooden crate or two. You’ll need a lot more before you can actually start crafting tin weapons and gear. Here is where you will find it:
Where to find tin
Tin Ore Core Keeper: where to find it
Tin ore appears in new biome, Clay caves. Since the Core Keeper maps are procedurally generated, I can’t give you any exact directions, so just pick a direction from your starting point (Dirty Biome) and start tunneling out. If you reach a wall that your copper pickaxe can’t break. Turn around and head back to the Core, then take a different direction.
When searching for the Clay Caverns, make sure you have the following with you:
- Minimum 2 copper picks
- 30-40 bridge pieces
- 8-10 empty inventory slots
You will know you have found the Clay Caverns when an announcement message appears on the screen and you also hear the soundtrack change. On your minimap, the biome is shown in peach., indicating that you are digging a tunnel in clay, not mud. Here is a picture of my map shortly after I found the Clay Caverns to give you an idea of how far I had to go.
You can see the Core, the tunnel I made to the east, and the chasm I had to cross using parts of the bridge. Again, you may not find it in the same direction as me but the distance to it (according to my very rough estimates, about 150 blocks) will hopefully be about the same.
Once you’ve found the Clay Caverns, the tin ore deposits work the same as the copper deposits in the Dirty biome: you’ll be able to see the metallic sheen in the dark when you’re close enough. When you spot a glint, tunnel towards it. Tin ore will look like shiny silver and gray nuggets in clay.
While tunneling, you will collect a lot of clay and other new materials, so it’s good to have a few empty inventory slots. Clay is harder to dig than dirt, so it’s good to have extra copper picks on hand so you don’t have to go back to the Core for repairs when one of them wears out.
