Blaze Powder

Blaze Powder is an item made from a Blaze Rod obtained from a Blaze, crafting two at a time. It can be crafted together with a Slimeball into Magma Cream, with an Ender Pearl to create an Eye of Ender, or with Gunpowder and Coal into a Fire Charge. They can as well be used as the top ingredient on a Brewing Stand, when combined with an awkward potion it creates "Potion of Strength." When combined with a water bottle, it will create a mundane potion.
