Wild Breath D20

Through some form of Godly Blessing, Magic Artifact, a scientific or magical experiment you have, or any other method of obtaining power you have gained the ability to use all forms of dragon breath even some that a typical Dragonborn is incapable of using. Although you've gained the ability to use every elemental dragon breath you don't have the ability to choose which breath you use roll 1d20 to see which breath you use and then another 1d20 to see if your fire breath blows up in your face or if you successfully execute a perfect poisonous bite and retreat on the enemy.

You can use your action to exhale destructive energy. Your draconic ancestry determines the size, shape, and damage type of the exhalation. When you use your breath weapon, each creature in the area of the 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 to 3d6 at 6th level, 4d6 at 11th level, and 5d6 at 16th level. After you use your breath weapon, you can’t use it again until you complete a short or long rest.

Every time you use your dragon breath your color will change depending on your 1d20's roll until you use dragon breath again which will cause your color to change again depending on your roll.
