Corrupted Nodule

A polymer substitute from corrupted creatures

Corrupted Nodules are a resource from the Extinction DLC in ARK: Survival Evolved and ARK: Survival Ascended. The game warns: "These incredibly strong, lightweight nodules are somehow naturally made in corrupted creatures. Incredibly hazardous to human health if consumed." The ARK Wiki describes them as a stand-in for Polymer, similar to Organic Polymer, and they can also replace Organic Polymer when crafting Ghillie Armor. Our records place them on Extinction and Astraeos.

Harvesting them

Nodules are harvested only from the bodies of Corrupted Creatures, and they drop at a lower rate than Organic Polymer. Otherwise gathering follows the same rules as Organic Polymer, the same tools work, and the Chainsaw is the most efficient. The Moschops is the exception: its harvest escalation applies to organic polymer alone, not to variants like this one.

Recipes in each game

Our records list different recipes for the two games. In ASA there are 2: the Summon Kalydonios & Erymanthian and Summon Minotarchos tributes, each needing 25 nodules. In ASE the one listed recipe is Simple Augmented Kibble, which takes 5.

Spoilage, stacking and a warning

A nodule weighs 0.25, and a full stack weighs 5. Like Organic Polymer it stacks to only 20, which lets it fill a creature's inventory quickly. It spoils in 30 minutes. On an Achatina it gets the same longer spoil time as Organic Polymer, even though the Achatina cannot produce it, while Preserving Salt has no effect on its spoilage. Swallowing one deals 500 damage to the player, enough to kill most players at once, just as Organic Polymer does.
