Grokdrul is resource that can be found in Grineer camps on Plains of Eidolon, stored in drums. Grokdrul is also rewarded by Bounties and Incursions. The higher level the mission you take on the Plains, the more Grokdrul the player will obtain from drums, up to 5 per drum on the highest level missions.
Blueprints Requiring Grokdrul Edit
