As a standard action, you can breathe a gout of flame once per round for the duration of the spell.
You make a ranged touch attack with the flame (to a maximum range of 15 feet), dealing 1d8 points of fire damage per two caster levels (maximum 10d8) on a successful hit.
Fire breath ignites combustibles and damages objects in the area, and it can melt metals with low melting points (such as lead, gold, copper, silver, and bronze).
