The Zylon mod adds two new rarities to the game and adopts one vanilla tier.
|11||Purple||Even though purple is a vanilla rarity, no base game items have it as a tier. Most Zylon items that use purple as a base tier as a base are items crafted from Silvervoid Cores.|
|12||Bright Pink||This tier is for items obtained post Zylonian Mineral Extractor. This mainly includes items crafted from Galactic Diamondium, Ectojewelo Bar, and Infected Onyxes. This tier's color is a reference to the color of the Zylonian Mineral Extractor.|
|??||Sky Blue||Only two items use this rarity, the unobtainable Slimebender and the Polandball Mask.|
