Minecraft resource gathering/Netherite
Netherite is something that can not be found by mining, but gotten by crafting. 4 ancient debris and 4 gold in a crafting table creates a netherite ingot and like other ores, an ingot in every slot creates a block.
Netherite can sometimes be found in bastion chests.
You use 1 netherite ingot on a smithing table with a diamond tool, weapon, or armor to get a netherite version, keeping enchantments and durability percetage. Netherite items have higher protection, attack, durability, and enchantibility than diamond.
Netherite is a fictional material made specifically for Minecraft, and has no real world counterparts.
