Fireflow

You can use this spell to control non magical fires. The target fire in range can be moved about in any direction provided it is not through the air. The flames can even spread over surfaces like snow, ice and water. Objects and creatures contacting the fire do so as if they contacted the fire in its original form regardless of its current size and shape. A creature can only take one instance of this damage each turn. For example, if you used a lit candle as the source of the spell but made it grow to the size of an inferno, anyone stepping into the fire would only be burned as if they touched a lit candle.
