Minecraft wiki entry for Netherite, associated text: Netherite is a rare material from the Nether, used primarily to upgrade diamond gear. Netherite items are more powerful and durable than diamond, can float in lava, and cannot burn. All of the blocks are also unbreakable with explosion values of even 7/8, the highest in the game, although in item form they are destroyed upon contact with a cactus like any other item. Like obsidian, it can still be broken by blue wither skulls, which always drops the item.
