(W.I.P.)Westeros

You can identify whether food, drink, or a creature within 30 feet has been poisoned or is suffering from a disease. This is based on your knowledge of plants, toxins, and medical conditions. You can also recognize the type of poison or disease with a successful DC 15 Intelligence (Nature) check. The spell can penetrate most barriers, but it is blocked by 1 foot of stone, 1 inch of common metal, a thin sheet of lead, or 3 feet of wood or dirt.
