A Smithing Template is a new item in Minecraft that is used to customize and upgrade other items in a Smithing Table. There are two types of Smithing Templates in the game: Upgrade Template and Armor Trims. Upgrade Templates are used to upgrade diamond armor and tools to Netherite. Armor Trims are used to add patterns to armor. Smithing Templates are consumed when used, but can be duplicated using an existing template. They are found in various naturally generated structures throughout the Minecraft world, such as Pillager Outposts, Desert Pyramids, Shipwrecks, and more. To use a Smithing Template, take it to a Smithing Table alongside any piece of armor and a single piece of one of the following materials: Iron, Copper, Gold, Lapis, Emerald, Diamond, or Netherite.
