With the huge shake up to Itemization and Crafting that’s come to Diablo 4 Season 4 with Tempering and Masterworking, there’s also been an equally huge change to Crafting Materials.
Some items such as Paletongue, Grave Dust, or Crushed Beast Bones no longer exist and a few new items like Obducite have made their debut. In addition, most items have also had their sources changed in a number of ways, making old farming methods obsolete.
