Detect Poison/Disease | Ritual

For up to 10 minutes, 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.
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.
