Beginning at 1st level, you can channel your elemental power as an action to exhale a deadly barrage of energy. All creatures in the area that fail on a saving throw take 2d6 damage, and those that succeed take half damage. The area, the type of saving throw, and the type of damage all depend upon your dragon species. The saving throw DC equals 8 + your proficiency bonus + your Constitution modifier. The damage inflicted increases as shown on the table. You regain your use of this ability when you take a short or long rest. Starting at 6th level, you can use this ability twice between rests, and at 15th level you can use it 3 times between rests.

Your creature type is “dragon,” which renders you immune to effects that do not affect dragons, such as the charm person and hold  person spells.

You can fly at a speed of 60 feet. You can’t fly if you are carrying more than 1/3 your carrying capacity (which is 5 times your Strength score).

When you make an unarmed strike with your claws, you deal 1d6 slashing damage. You can also make an unarmed strike with a bite, for 1d6 piercing damage, or with your tail, for 1d6 bludgeoning damage. Your claws are not well suited to tool-use or fine manipulation. You have disadvantage on attacks with manufactured weapon, and on ability checks that require fine manual dexterity (such as using thieves' tools or the Sleight of Hand skill).

A dragon of your age is over 20 feet long, with a 25 foot wing span, and weighs 1000-2000 lbs. Your size is Medium, but just barely.

As powerful creatures who are not afraid to express themselves and impact the world around them, dragons tend away from neutrality and towards the extremes of the alignment scale. Although each dragon species has a typical alignment, dragon player characters are exceptional members of their species and may have any alignment.

You have outgrown the wyrmling phase, and are around 6-15 years old. Dragons reach full adulthood at about age 100, and can live to be thousands of years old.

Your Strength score increases by 2 and your Charisma score increases by 1.

Your base walking speed is 30 feet so is your climbing speed

As supreme predators and frequent cave-dwellers, dragons have superior vision in dark and dim conditions. You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light. You can’t discern color in darkness, only shades of gray.

When you are not wearing armor, your scaly hide provides you with AC equal to 10 + your Strength modifier + your Dexterity modifier (maximum Dexterity modifier +2). Due to your body shape and movement patterns, you can’t effectively wear manufactured armor are always treated as lacking proficiency with it.

You have advantage on saving throws against being frightened.

You have resistance to a damage type, according to your dragon species.

You speak Common and Draconic. Draconic is one of the oldest languages, often used for important magical writings. It contains many hard consonants and sibilants, making it difficult for lesser creatures to master.

Unlike other characters, you don’t get to select a background. Instead, all dragons get the wyrmling background.

Choose one of these species. Each defines the damage type of your damage resistance racial feature, as well as the damage type, area, and saving throw ability of your Breath Weapon class feature.
