Draconic Paragon

This spell is so powerful that even ancient dragons offer respect to those capable of casting such a spell. You cover yourself in the raw arcane might of the mightiest of dragons, transforming you into a monstrously powerful draconic demigod, granting you the following benefits that last until the spell ends:

• Your body is covered in draconic scales, making it so that your AC = 18 + your Dexterity modifier while you are or aren't wearing armor. While you wear armor, the armor adds its normal bonus but you treat your armor class as if it is 18 instead of 10.
• Your hit point maximum, and overall hit points, is increased by 2d10, as your body is enjuvenated with power.
• Your eyes glow brightly and your other senses are amplified beyond most mortal creatures, granting you darkvision out of a range of 240 feet, and blindsight out of a range of 120 feet.
• You grow massive, roughly 20-foot wide wings from your back, granting you a flying speed of 75 feet, which is reduced by 5 feet when you are wearing heavy armor. When you are walking on the ground, you can reabsorb these wings into your body (no action required).
• Your body enlarges to fully encompass the massive amount of draconic energy you now wield, causing your size to increase by one (for example, Medium to Large).
• You gain the ability to unleash a mighty blast of raw draconic power in the form of a breath weapon. On your turn, as an action, you can exhale destructive energy in either a 50-foot cone or a 90-foot line that is 5 feet wide. Each target within that area must make a Constitution, Charisma, or Dexterity saving throw (your choice when you transform) against your spell save DC, taking 9d12 damage on a failed save, or half as much on a success. The damage type is which one you choose when you transformed. After you have used your breath weapon once, you cannot use it again until at least 2 minutes have passed.
• Your hands grow into taloned weapons that are partially coated in elemental energy. While you have these claws, you can make unarmed strikes with them. When you hit with them, the target takes 1d8 slashing damage + 2d6 damage of your breath weapon, instead of the normal bludgeoning damage of your unarmed strike.
• You grow a long snapping tail (or if you already have a tail, it transforms into a longer and more draconic version) that you can make unarmed strikes with. When you make an unarmed strike with your tail, the reach is 10 feet and on a hit, the target takes 1d10 bludgeoning damage + 2d6 damage of your breath weapon, instead of the normal amount of bludgeoning damage from a normal unarmed strike.
• Your very essence is imbued with draconic majesty, granting you advantage on Charisma saving throws and on Charisma checks against non-true dragons.

When you transform, you choose a damage type and a species of true dragon whose breath weapon deals the damage type. When you transform, your wings, claws, horns, tail, and other physical attributes caused by the spell perfectly resemble the corresponding body parts of whatever species of true dragon you choose, and your breath weapon deals that same damage type.  While transformed, you can still cast spells and wield your weapons, though you cannot cast ritual spells.
