wulfrum is found in layers 10 and -64 its resistance is greater than diamond but less than netherite
Cobalt is a more resistant mineral than iron but it is still inferior to diamond, it is found in layers 80 and -30
Bronze is a very common mineral found at altitudes 200 and 0. Its resistance is lower than that of iron, but its high frequency makes its creation convenient for the early game.
And finally we have the crystal equipment, the ultimate mineral stronger than netherite, it is located at height 5 and -64 but its mineral can only be extracted with netherite tools
To create the crystal ore we must have 4 of these in addition to 4 diamonds, we place them on the crafting table and we will have an ingot
and finally we place the crystal ingot next to Wulfrum's tools
