The Dragon

Your patron is one of the oldest of Legendary creatures, a magical being that few could hope to understand and fewer still could hope to approach in power. Dragons are fueled by their own motivations and desires, they might send their warlocks on missions to help or hinder other beings, to destroy another dragon before it becomes more powerful, to obtain rare treasure or an artifact, or just to gather information for the creature in its cave. A dragon that could have a patron might be Balagos the Flying Flame, Calathanorgoth the Old One, or Chardansearavitriol the Ebondeath.

Note: You require the Player's Handbook in DNDBEYOND in order to utilize this class effectively. It contains spells that only appear in the Player's Handbook. You will need to add those manually or just know what they do.

Draconic Rage

Starting at 1st level, When you are hit by an attack, you may use your reaction to add an amount to your AC equal to your Charisma modifier (minimum of 1), potentially turning that attack into a miss. This benefit lasts for one minute, or  until you miss an attack. While this benefit lasts, you deal an additional 1d4 damage of your choice between acid, lightning, cold, poison, or fire damage when hitting an enemy with a spell. 

Once you use this feature, you may not use it again until you complete a long rest. 

Eye for a Hoard

Starting at 3rd level, your patron's knowledge of magic items and treasure is yours to tap into. You may cast the identify without expending any spell slots or using any components.

You may use this feature an amount equal to your Charisma Modifier. All uses replenish on completion of a short or long rest. 

Draconic Presence

Starting at 10th level, the magic of your Dragon patron imbues your Draconic Rage with even more destructive magic. When you activate your Draconic Rage, translucent dragon wings sprout out of your back, and you gain a flying speed of 30 feet. Additionally, your choice of one creature within 5 feet of your location at the end of your turn while Draconic Rage is active must make a DC 15 DEX saving throw. On a failure, that creature takes 2d6 damage of a type of your choice between poison, acid, fire, lightning, or cold. 

Additionally, your Draconic Rage now recharges on a short or long rest. 

Breath Mastery

Starting at 14th level, you have attained mastery over the draconic magic your patron has granted you. You can even extend this power to others.

You may cast the spell Dragon's Breath at will, without expending a spell slot. You have advantage on saving throws made to maintain concentration on this spell.
