A new skill in vision towards mythical (or a SoW item/artefact?) that lets you see more information about a dead target. It may include butcherable components, quest information (vague like keylist), and
target keywords.
Another option would be to bring corpses to a denizen for this information. Sallust or the Theran Taxidermist are examples, it could be multiple mobs depending on the type. Theran Taxidermist for example would only give reliable information about fish. Sallust only about girls and women. Talus about animals only. etc etc.
