4SRD > Dragon's Blast

Dragon's Blast: You have the dragon's blast Dragonkin racial ability.
As you open your mouth with a roar, the deadly power of your draconic kin blasts forth to engulf your foes.
(Swift Action, a close blast in a cone extending 15 feet from you)
Once per encounter, you can breathe out deadly energy which attacks every creature in a cone of 15 feet from yourself.
Attack with Strength, Constitution, or Dexterity +2 vs. the Reflex defense of every target. (At 11th level the bonus increases to +4, at 21st level, the bonus increases to +6.) If you hit, you deal 1d6 + Constitution modifier damage. (At 11th level the damage increases to 2d6 + Constitution modifier damage; at 21st level, the bonus increases to 3d6 + Constitution modifier damage.)
Special: When you create your character, choose Strength, Constitution, or Dexterity as the ability score you use when making attack rolls with this power. You also choose the power’s damage type: acid, cold, fire, lightning, or poison. These two choices remain throughout your character’s life and do not change the power’s other effects.
