Jazzium

Jazzium: It's strong, fancy, and hard to obtain!

Step 1: Locate some Jazzium Ore in the Nether

Step 2: Mine it with a Diamond Pickaxe or better

Step 3: Smelt the ore into Jazzium Ingots

Step 4: Combine the ingots with Blaze Powder to create Flamed Jazzium Ingots

Step 5: Craft Tools and Armor with the Flamed Jazzium Ingots

(Note: the tools require blaze rods instead of sticks!)
