You have made a pact with the dragon god Tiamat,  God of all Chromatic Dragons or Bahamut, God and of Metallic Dragon, or a Legendary Dragon with similar power who aims for absolute evil or good to spread across the world to smite the other or some other similar goal that equates to doing good or evil. Corruption, Dread, Death, and Destruction are one of the many desires of your patron if it tends to be a chromatic dragon or Tiamat. Meanwhile with Bahamut or Metallics desires for Purity, Hope, Life, and Righteousness. Though one common theme between both is Greed for gold and Power.

Dragonic Body

At 1st level, your body grows retractable claws and a tail, both of which you are proficient with using. You use your strength mod for the attack and damage rolls of your claws and tail.

If you hit with the claws, they do 1d4 + strength mod slashing damage.

If you hit with the tail, the creature make a constitution saving throw equal to your spell save dc. If they fail, they take 1d8 + strength mod bludgeoning damage and are knocked prone. If they succeed, they take half damage and are not knocked prone.

The Tail can be used as an action while the Claws can be used as a bonus action.

The damage for your claws increases to 2d8 at 14th level, and the damage for your tail increases to 3d8 at 14th level

Draconic body

At 6th level, whenever you cast Eldritch Blast, you can change the damage type of the blasts between fire, acid, poison, cold, and lightning. The eldritch blasts shoot from your mouth rather than from your spellcasting focus

Additionally, your hit point maximum increases by 6 and increases by 1 again whenever you gain a level in this class. Additionally, your unarmored AC is now 13 + your DEX modifier. You may still wear a shield and retain this benefit.

Legendary surge

Starting at level 10 you can use the legendary power of your patron three times per short or long rest to shoot a single blast from Eldritch Blast with the damage type of Fire, Acid, Poison, Cold, and Lightning at a creature within range at the end of any turn in combat besides your own.

Furthermore you can choose to use a tail attack in place of this blast which on hit will knock the creature prone though you can only do this once per round.

Draconic Ascension

At 14th level you invoke the might and power of your patron as an action to gain the following effects for 1 minute

• You gain a flight speed equal to your running speed as you grow draconic wings of eldritch energy.
• You take reduced damage from all sources equal to your charisma modifier. You also deal extra damage equal to your Charisma modifier once per round
• You gain blindsight equal to 15 feet and temporary hit points equal to your level in this class.

You regain the use of this feature after a long rest

Your Legendary Surge uses go up from 3 uses per short or long rest to 5 per short or long rest once you gain this feature.
