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

Dragonkind reach maturity at around the age of 15, they however are not bound by a limited lifespan and can live for as long as they are not slain. The oldest recorded dragon in history was said to be over 4000 years old.

Dragonkind are the same size humans, standing well between 4 and 6 feet tall and averaging almost 150 pounds. Your size is Medium.

Your base walking speed is 30 feet.

A destructive well of energy dwells within your core. Choose a damage type (fire, cold, acid, poison, lightning, thunder) and either a 15 foot cone or a 30 foot line as the area of effect. This is your Elemental Surge and cannot be changed later. You must activate your Dragon Form before you can unleash this energy (described below).

Elemental Surge

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.

You have resistance to the damage type associated with your draconic ancestry.

You can speak, read, and write Common and Draconic. Draconic is thought to be one of the oldest languages and is often used in the study of magic. The language sounds harsh to most other creatures and includes numerous hard consonants and sibilants.

The color of your eyes projects a light that only you can perceive. 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 most color in darkness, only shades of whatever color your eyes are.

You can retract or extend a pair of horns or a tail from your body anytime during your turns. Damage dealt to these cosmetics can damage them but deal no damage to you. Broken cosmetics are repaired at the end of every long rest.

As an action you can temporarily transform into a full dragon. This transformation lasts for 1 hour or until you end it as an action. At level 10 this transformation lasts for 4 hour or until you end it as an action. At level 16 this transformation lasts for 8 hour or until you end it as an action. Once you use this trait, you can't use it again until you finish a long rest. As a dragon you gain the following features:

Size

Your size becomes large, and your weight is quadrupled. If there isn't enough room for you to increase your size, you must immediately activate the Adaptability trait (described below).

Wings

You grow a pair of wings, granting a flying speed of 50 feet. Your wings require at least a 20 foot radius of free space to fly

Natural Weapons

You possess a row of sharp teeth, powerful claws and devastating tail which can replace your unarmed strikes, dealing 2d6 + your Strength modifier slashing (claws) damage, or 2d10 + your Strength modifier piercing (bite) plus 2d4 Acid damage (In case of Black Dragon), or 2d8 + your Strength modifier bludgeoning (tail) damage.

Multi-attack

The dragon can use its Frightful Presence. It then makes three attacks: one with its bite and two with its claws or Tail.

Natural Focus

You can cast spells without requiring a focus

Natural Armor & Equipment

You choose whether your equipment falls to the ground in your space, merges into your dragon form, or is worn by it. Worn equipment functions as normal, but the DM decides whether it is practical for the dragon form to wear a piece of equipment, based on the size. If you are not wearing armor, your AC becomes 13 + your dexterity modifier + your Constitution modifier.

Breath Weapon

As an action, you can unleash your Elemental Surge originating from you and cause creatures within range to make a Dexterity saving throw. The DC for this save 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 4d6 at 4th level, and 8d6 at 8th level. and 12d6 at 12th level. and 16d6 at 16th level. and 20d6 at 20th level. You can unleash your breath weapon a number of times equal to half your level (rounded up) each time you transform.

Adaptability

You can choose not to fully transform into a dragon before activating your Dragon Form trait. If you do so, your size doesn't change, you don't gain natural armor, and you continue to appear mostly as your untransformed self. All other features from transforming, such as your wings, natural weapons, natural focus, and breath weapon still apply. Your fingers become claws, your teeth sharpen, and a pair of wings stretch out from your back that require at least a 5 foot radius of free space to fly

You have proficiency in the Perception and Insight skills
