Draconic Attribute

At 1st Level, You develop dragon-like attributes that manifest at your will. You have a pool of d6 dice that you expend for this feature. The number of dice in the pool equals double your Charisma Modifier + your Warlock Level. Your pool regains all expended dice when you finish a long rest. As a Bonus Action, you expend dice from this pool, up to an amount equal to half your Warlock Level (rounded up). Upon doing so, you gain one or more of the following benefits listed below. If you so choose, you can gain multiple attributes at once with a single use, provided the number of expended dice fulfill the requirements of all selected Draconic Attributes, combined. For instance, if you expend 3d6 dice from your pool, you can gain Draconic Beauty, Draconic Sight, and Dragonic Weapon all at once, 1d6 expended for each one. A Draconic Attribute, once gained, lasts for 1 hour, until you end it willingly (No Action required), or until you are incapacitated or die.

Draconic Beauty. Prerequisite: 1d6, up to 2d6. You shimmer with dragon scales, the beauty of which can deflect harm. When you aren’t wearing armor, your AC becomes 13 + your Charisma modifier. This increases to 15 + your Charisma modifier if you expeneded 2d6 for this attribute.

Draconic Defiance. Prerequisite: 3d6. You have the legendary resistance of a dragon. Once per round for the duration, when you make a saving throw, you make it with advantage.

Draconic Dominance. Prerequisite: 3d6. You take action with draconic might. Once per round for the duration, when you make an attack roll or ability check, you make it with advantage.

Draconic Fury. Prerequisite: 1d6, up to 3d6. You have a wrathful temperament that spills over into your magic. Once per round for the duration, when you deal the damage type associated with your dragon patron with a spell or Warlock feature, roll the dice expended and add them together. This amount is added to one damage roll of your spell/feature.

Draconic Majesty. Prerequisite: 7d6. You exude the might and awe of a dragon. As a part of gaining this Draconic Attribute and as a Bonus Action on subsequent turns within the duration, you can cause any creature of your choice that you can see within 30 ft. of you to make a Wisdom saving throw. Upon a fail, a creature is frightened of you for 1 minute, repeating this save at the end of its turns for the duration. While frightened in this way, a creature's movement speed is 0. Upon a success or if the effect ends, a creature is immune to being frightened by you for the next 24 hours. Whenenever you use this action, creatures that are already frightened of you in this way makes its next repeated saving throw with disadvantage.

Draconic Sight. Prerequisite: 1d6, up to 7d6. Your eyes glow with draconic awareness. You have darkvision of 60 ft. in range and blindsight of 20 ft. in range. For every 2 dice expended beyond the first die, this darkvision gains a +30 ft. bonus and this blindsight gains a +20 ft. bonus.

Dragonic Vitality. Prerequisite: 1d6, up to 3d6. Your heart beats with dragon's blood. At the start of your turns within the duration, roll the expended dice and add them together. You heal for this amount.

Dragonic Weapon. Prerequisite: 1d6, up to 2d6. You grow a draconic appendage that can be used as a weapon. When you make a weapon attack using this appendage, you can use Charisma instead of Strength or Dexterity for the attack and damage rolls. This appendage is a natural weapon, which deals 1d6 magical damage on a hit. Once per turn for the duration, when you make a weapon attack with the appendage, roll the dice expended and add them together. This amount is added to the damage roll of the attack, and is the damage type associated with your dragon patron. Additionally, If you take the "Pact of the Blade" feature, the appendage gains the benefits of, and is treated as, a pact weapon. The appendage you can choose are among the following for the duration:

Dragonic Horn. Gnarled, jagged horns grow from your brow, the damage type of which is piercing damage.

Draconic Tail. You grow a long, menacing dragon tail, the damage type of which is bludgeoning damage.

Draconic Talons. Your fingernails sharpen to a violent razor, the damage type of which is slashing damage.

Draconic Wings. Prerequisite: 5d6, up to 8d6.  You spawn majestic dragon wings. You gain a flight speed equal to your movement speed. For every die expended beyond the fifth die, this flight speed gains a +10 ft. bonus.

You can benefit from a maximum of 3 Draconic Attributes at a time. However, this maximum increases to 4 attributes at a time at 10th Warlock Level, and to 5 attributes at a time at 18th Warlock Level. 

Devouring Destruction

At 6th Level, Your draconic power can consume a victim whole. You can maximize one damage roll you deal through a weapon attack, spell, or Warlock feature, so long as the damage roll contains the damage type associated with your dragon patron (no Action required). Upon doing so, you gain an amount of temporary Hit Points equal to half the damage dealt, gaining the full amount if the damage had slain your target.

You can use this feature up to an amount of times per short or long rest equal to your Charisma modifier.

Scaled Retribution

At 10th Level, Beautifully reflective scales that shimmer with dragon's rage scatter across your body. When you take damage from an attack or spell, you can use your Reaction to halve the damage roll. The damage roll is instead reduced to 0 if it contains the damage type associated with your dragon patron. The attacking creature then takes an amount of damage equal to the amount of damage that was reduced by the reaction. The damage type of this reflected damage is the one associated with your dragon patron, and it ignores any resistances your attacker has against that type. 
For instance, if you have an Ancient Red Dragon as your patron and you take 10 slashing damage from an attack, you can use this reaction to halve the damage down to 5 slashing damage. Your attacker then takes 5 fire damage. If the attack instead dealt 10 fire damage, this reaction reduces the damage to 0, and your attacker takes 10 fire damage. Additionally, as part of this reaction, you can choose to expend a "Pact Magic" spell slot in order to convert all damage types dealt by the oncoming attack/spell into your dragon patron's damage type.

You can use this feature up to an amount of times per short or long rest equal to your Charisma modifier.

Additionally, you gain the following benefit:

Eldritch Surge. You swell with eldritch, draconic fury. You can expend 5d6 of your "Draconic Attribute" feature's dice pool in order to regain one expended "Pact Magic" spell slot (no Action required). You can do so once per short or long rest.

Ancient Breath

At 14th Level, You possess the ever-feared breath of your ancient dragon patron. As an Action, you can exhale a dragon breath attack in a 90-foot cone. The damage type dealt by this breath attack is the one associated with your dragon patron. Each creature in that area must make a Dexterity saving throw, taking 10d10 damage on a failed save, or half as much damage on a successful one. A creature makes a Constitution saving throw instead if the breath attack deals either cold or poison damage. The damage roll of this breath attack increases by 1d10 for every Warlock level you reach that is above 14, totaling to 16d10 damage at 20th Warlock Level. 

You can use this feature once per long rest.
