1-level Divination (ritual)
For the duration, you can sense the presence and location of poisons, poisonous creatures, and diseases within 30 feet of you. You also identify the kind of poison, poisonous creature, or disease in each case.
Though this does not automatically enable you to treat the poison or disease, you or another creature you help can make WIS (Medicine) or WIS (Animal Handling) checks to treat or handle the respective poison, disease or poisonous creature with advantage and treat a roll on the d20 of 9 or lower as a 10.
