Iridium

Iridium is a material that can be used to upgrade Netherite tools and armor.

There are three ways of obtaining Iridium:

Irirdium Ore spawns in the End dimension, twice per chunk, between y=40 and y=10.
Iridium Fragments can drop from deepslate at a 1/1000 chance.
Iridium Fragments can also drop from any Purpur block at a 1/100 chance while using a Netherite or Iridium brush to break the block.

Iridium Fragments can be combined in a Crafting Table into an Iridium Chunk. Iridium Ore and Iridium Chuk can be smelted in a Furnace.

Netherite gear can be upgraded to Iridium through the Netherite Forge
