Shield Flame

Most miners and cavern explorers consider this simple spell far more important than your average mage. When cast, it protects an open flame from exposure to drafts and volatile gases. For the duration of the spell, nonmagical gusts or breezes are unable to extinguish the torch. Any vapors that would normally explode upon contact with fire (such as black damp or carbon monoxide) have no effect on a shielded flame. Of course, the spell may also be applied above ground to areas too windy to hold aloft a lit torch or candle.
