Description: Your breath weapon can now develop wild winds

Prerequisites: STR 13, Power Attack, Breath Weapon, Size Large or Larger

When you use your breath weapon, in addition to its normal effects, creatures in the area are affected as through struck by wind effects. The force of the wind depends on your size, as indicated below. Because your breath weapon has an instantaneous duration, creatures ignore the checked effect unless they are airborne (in which case they are blown back 1d6×5 feet).

When you use this feat, add +1 to the number of rounds you must wait before using your breath weapon again.
