***intended for the half-dragon race*******

Extensive training has granted you greater control over your Breath Weapon.

Increase your Strength, Constitution, or Charisma score by 1, to a maximum of 20.

Breath Weapon. You can use your bonus action to exhale destructive energy. Your draconic ancestry determines the appearance and damage type of the exhalation.

When you use your breath weapon, each creature in the area of exhalation must make a saving throw, the type of which is determined by your draconic ancestry. The DC for this saving throw equals 8 + your Constitution modifier + your proficiency bonus. A creature takes 2d6 damage on a failed save, and half as much damage on a successful one. The damage increases by an additional 1d6 at 6th level, 11th level, and 16th level.

After you use your breath weapon, you can't use it again until it's recharged. At the start of each of your turns, provided you already used your breath weapon, you may roll a d6. On a 6, you regain the use of your breath weapon. Otherwise, your breath weapon recharges 1 minute after you used it.
