Either your Strength or Dexterity score increases by 2, your Constitution score increases by 1, your Intelligence score increases by 1, and your Charisma score increases by 1.

Trapped dragons live just as long as they would if not trapped, age showing very slowly if it shows at all.

Trapped dragons usually retain the alignment they had before becoming trapped, but the traumatic experience of becoming trapped may push the dragon to change to a different alignment, whether for the better or the worse.

The form of the trapped dragon is generally that of an elf, half-elf, or human with draconic touches such as scales or horns which are often hidden with illusory magic. As such, your height and weight while trapped match that of the race you are trapped in. Your size is Medium.

Your base walking speed is 35 feet.

Though you are now trapped in a humanoid form, you still maintain some abilities from your original shape. Eventually, you may even be freed from your trapped state, giving you access to your true form and full abilities. Choose one type of dragon from the Draconic Form table. Your breath weapon and damage resistance are determined by the dragon type, as shown in the table.

Draconic Form

At 1st level, you can recall the way your claws were formed on your draconic body and cause them to materialize from your fingers. As an action, you can make an unarmed attack with your claws, doing 1d6 slashing damage in addition to damage equal to your Strength modifier. You are proficient with this attack.

Once you reach 5th level, you can use your action to exhale destructive energy. Your draconic form 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 form. 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. Unfortunately, unlike Dragonborn, you do not have protection against wounding yourself from using your breath weapon. Any time you use your breath weapon, take 1d4 damage of the type determined by your draconic form, halved by your resistance to that damage type. This damage increases to 2d4 at 6th level, 3d4 at 11th level, and 4d4 at 16th level.

At 10th level, whether your freedom from your trapped state is gained or not, you can use an action to recall the way your wings were formed on your draconic body and cause them to materialize from your back.

Your wings remain for 10 minutes or until you end your transformation as a bonus action. While your wings are on your back, you gain a flying speed of 50 feet.

Once you use this trait, you can’t use it again until you finish a long rest.

At 15th level, whether you are freed from your trapped state or not, you are able to use an action to recall how your draconic body felt as a whole and temporarily push past the magic trapping you to return to that draconic body.

The transformation lasts either for three rounds, after which you return to your humanoid shape, or until you end the transformation with a bonus action. While you are transformed, you regain all the stats and abilities of the type of dragon you transform into, including Legendary Actions. When your transformation ends, you gain a level of exhaustion.

Once you use this trait, you can’t use it again until you finish a long rest.

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

Besides the scales or horns that remain on the now humanoid dragon, the only other feature that remains permanently are the trapped dragon’s eyes, which retain their original color and darkvision. 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.

If no spellcasting ability previously existed, the magical scar of the trapped dragon’s wound will provide it. Some spells are the same across each dragon, but others are unique to their color. All cantrips and first-level spells granted by this ability can be cast once per short rest, while the remainder of the spells can be cast once per long rest. For these spells, your Intelligence modifier will be used to cast, even if your class uses a different modifier.

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.
