The user can survive temperatures of -60 degrees to +200 degrees Fahrenheit, but only when uncovered. Any part of her body covered by clothes will not receive the magical protection. Any other class can use this oil, but witches are very secretive about its nature (reflected in the price). This oil can also safely used with any other type of body potion or oil, in particular Flying Ointment.
The oil’s effects last 6 hours, typically midnight till dawn.
