Netherite Upgrade is the smithing template that turns diamond armor and tools into netherite at a Smithing Table, making them tougher and stronger. This item is consumed upon use but can be duplicated using a Netherite Upgrade template, netherrack, and diamonds.
Netherite Upgrade templates are found exclusively in Bastion Remnants. Upgrading to netherite improves durability, knockback resistance (for armor), and mining efficiency (for tools). Once obtained, players can duplicate the Netherite Upgrade using the crafting recipe below, ensuring a steady supply for future upgrades.
