Breath of the Fire Dragon

This spell is a prayer to the Dragon of Fire, one of the mightiest of celestial beings, entreating him for a bit of his power. If the spell is successful, you gain the ability to breathe a bolt of flames from your open mouth once per Round as a Simple Action. The bolt has a DR equal to your Fire Ring and strikes every target in front of you within the area of effect. You may choose to take actions other than breathing fire while under the effects of this spell, but you cannot speak or cast spells. The spell expires after four Rounds, but you may choose to end this spell during the Reactions Stage of any earlier Round.
