Crucible is the final item you need for a forge in 7 Days To Die as of Alpha 19.
It unlocks the ability to craft forged steel and it’s one of the best items in the game.
Here’s how you can find or make a crucible in 7 Days To Die.
How to find or craft a crucible
You should be able to buy a crucible from one of the traders but there’s no telling when it will be available.
It should also cost quite a bit, which is over 8,000 coins.
Another way is to craft a crucible via a schematic or the Advanced Engineering level 5 perk.
If you use the perk method, you will need less materials to craft a crucible and also to craft all forge items.
Once you have a crucible, you can start making forged steel using iron and clay.
Forged steel will unlock a lot more items for you.
