Detect Poison and Disease

“Spiritual (divination) or Elemental (poison), 1st level (ritual)”

For the duration of the spell, you can sense the presence and location of poisons, venomous creatures, and mundane diseases within 30 feet of your reach. You can also identify the type of poison, venomous creature, or mundane disease in each case. Identifying a disease in this way does not reveal its treatment, only what disease it is.

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.

At Higher Levels. When you cast this spell using mana points equal to a spell of 5th level or higher, you can also feel and identify magic diseases.
