In addition to being a brewing ingredient, blaze powder is needed to fuel a brewing stand. Each piece of blaze powder can brew up to 20 batches of potions.
Blaze Rods are used to create Blaze Powder. Once a player combines a Blaze Powder with an Ender Pearl, they will create the Eyes of Ender. Players will need to create 12 of them to unlock the hidden passageway into the End, the location where players can face off against the Ender Dragon.
