Cladding Smithing Template
Cladding Smithing Templates were added with the 1.20 update.
Cladding Smithing Templates are used, along with Crude Cladding to upgrade Leather Armor into Cladded Armor within a smithing table.
They can be obtained as a guaranteed from from Pillager Patrol Leaders and as loot from the Pillager Outpost Chest.
They can be duplicated by crafting them along with an Iron Ingot and Mesmerite.
