Blizzard has confirmed changes will be made to the way Rawhide and Iron Chunks work in Diablo 4 following complaints and criticism from players. Both of these items are used to upgrade items like armor, weapons, and jewelry, making them crucial for players aiming to turn their character into a demon-slaying god. However, the drop rates for both Rawhide and Iron Chunks are quite low, leading developer Blizzard to address this issue directly in a new Diablo 4 update.
