Blaze Rods are items in the game Minecraft that are obtained by defeating Blazes, which are fiery creatures found in Nether fortresses. Each Blaze drops 0-2 Blaze Rods upon defeat, and they are essential for crafting various items and potions. These rods can be used to create Blaze Powder, which is a key ingredient for brewing potions and for crafting Ender Eyes. Blaze Rods also serve as a fuel source in furnaces, burning longer than most other fuels, making them valuable for smelting and cooking items efficiently.
