Prerequisite: Must be wearing a Blue Dragon Pendant
You can use your bonus action to breathe a storm of lightning. When you use your storm breath, each creature in the area of the storm must make a Dexterity saving throw. The DC for this saving throw equals 8 + your Dexterity modifier + your proficiency bonus. A creature takes 3d6 lightning damage on a failed save, and half as much damage on a successful one. The damage increases to 4d6 at 6th level, 5d6 at 11th level, and 6d6 at 16th level.
You have three charges that recharge at dawn.
