Prerequisite: Requires kobold race
Your draconic bloodline manifests itself.
You grow wings, granting a flying speed equal to your movement.
You can use a bonus action to exhale destructive energy. Your draconic ancestry determines the size, shape, and damage type of the exhalation. The DC for this saving throw equals 8 + your Dexterity modifier + your proficiency bonus. A creature takes 2d4 damage on a failed save, and half as much damage on a successful one. The damage increases to 4d4 at 5th level, 6d4 at 10th level, and 8d4 at 15th level. After you use your breath weapon, you can’t use it again until you complete a short or long rest.

Probably the most reasonable Kobold feat in the homebrew section but fire breath shouldn't be Dexterity-based.
i like it but since this feat is now for an older version of the kobold race, im recreating it for the updated version
