To produce Spoiled Meat, store raw meat in containers or creature inventories and let it decay, separating stacks to help pieces spoil individually. Feed troughs and large storage containers can accumulate a steady supply over time. Harvesting carcasses in areas such as the Ragnarok Highlands, beaches near the Wyvern Trench, or Fjordur’s Swamp Island can yield large amounts, while a Desmodus is also useful for gathering it.
