Netherite Ingot

Netherite ingots are crafting materials used to make the strongest-tier tools and armor that are stronger than diamond. Unlike other items, it does not burn in lava.

Obtaining
Netherite ingots are obtained by crafting four netherite scraps and four gold ingots. It is a shapeless recipe, therefore the placement of the netherite scraps and gold ingots does not matter when crafting it.

Crafting ingredient
Note that when crafting any netherite equipment, anything that classifies as NBT data that is on the diamond item, is not passed on to the new netherite item including any enchantments or durability losses.

Repairing
Netherite ingots can be used to repair the following items in an anvil:

Beacons
Netherite ingots can be used to select powers from a beacon. The player must select one of the available powers, and then insert an ingot in the item slot.

A netherite ingot can be substituted for an emerald, a gold ingot, iron ingot, or a diamond. The gold option would consume 3 less gold and no netherite material.
