if database doesnt show coords then they dont exist

Snowycookie - Sanctuary

FB19 Human cave has those monsters. But that material does drop from other monsters, try the bugs around archosaur.

Your best bet for oil is the mobs around Hidden Orchard. Argenweave Mantis and Backstabbing Scorpion.

Just take the mobs that said ''world with coord under it'', if there's a ''-'' that mean we don't have thoses mobs.
