Candletrick

The wu jen casts this spell on a small fire source of a type typical for lighting purposes. During the duration of the spell, the flame cannot be extinguished by normal means. The candle will immediately relight if snuffed, except if placed underwater or in a strong wind (such as gust of wind), or if the air or fuel supply is cut off. This spell will not work on fires larger than a small campfire.

Notes: Uncommon in oriental settings; otherwise very rare. (Updated from Dragon Magazine)
