Oil is a critical resource for advanced crafting in ARK: Survival Ascended. Found underwater, in desert biomes, and from oil-producing creatures like the Dung Beetle.
Node yields assume the base harvest HP from game data (e.g. 1000 for Redwood trees, 620 for Metal nodes). In-game, trees and rocks with bAllowHarvestHealthScaling have per-instance HP that varies with the node's size, so actual yields per node will vary. The values shown represent the average.
14,044 harvestable nodes across 10 maps · 7 node types
