Embodiment of the Platinum Dragon

Golden Spirits

Starting at 3rd level, you gain the aid of celestial emissaries that take the form of of tiny golden birds, pseudodragons, or other suitable flying creatures. These spirits constantly fly or rest around you, going no further from you than 10 feet away, unless required to by one of your features. You have a number of these spirits equal to 1 + your proficiency bonus.

As a reaction when you or one of your allies within 60 feet would take damage, you cause one of your spirits to interpose itself between the target and the source of damage, reducing the damage taken by an amount equal to half your demi-dragon level (rounded down) + your Charisma modifier (minimum 1). Damage taken can not be reduced below 0. The spirit's energy is then expended and it cannot be used again until you have finished a long rest.

Platinum Decree

Also at 3rd level, you gain proficiency in Persuasion. If you already have this proficiency, you instead gain proficiency in another skill of your choice.

Additionally, you can use your action to make a Decree, commanding a target within 60 feet to cease violent acts for 1 minute. At the start of each of its turns, the target must make a Wisdom saving throw against your Dragon Spark DC. On a failure, the target cannot make an attack or force an unwilling creature to make an ability check or saving throw. On a successful saving throw, the Decree ends. A creature can choose to automatically succeed this saving throw, and if it does so, you have advantage on attacks against it until the end of your next turn.

On a successful save, the creature is immune to this effect for 24 hours.

Celestial Soul

Your ever strengthening devotion to your ideals has aligned your being with the forces of the heavens, suffusing your body and soul with radiant energy.

Starting at 6th level, once per turn when you roll damage with a natural weapon, you deal an additional 1d6 radiant damage.

Additionally, when you use your Dragon's Breath feature, you can change its damage type to radiant. If it's damage type is already radiant, it deals an additional 1d8 radiant damage.

Walk Among Them

Following in the steps of your inspiration, you have learned to retake a humanoid form to allow you to better converse with the people of the world.

At 6th level, you learn a language of your choice, and you can shapeshift into a medium or small humanoid with an appearance of your choosing as an action. This appearance is your persona, and once chosen, its appearance cannot be altered.

While your shape is changed in this way, you still benefit from your race and class features, briefly manifesting claws, wings or whatever else is required to use your features, though you can choose to conceal these manifestations as mundane strikes or other non-draconic abilities. You can revert to your true form as an action.

You gain an additional persona and learn an additional language at levels 10 and 17.

Breath of Heaven

At 10th level, your innate connection to celestial forces has empowered your Dragon's Breath.

As an action, you can exhale a radiant wind with an area equal to your Dragon's Breath Cone Range. Creatures of your choice within that area, including yourself, regain hit points equal to your Dragon's Breath damage.

You can use this feature once, and regain the ability to do so once you finish a long rest.

At 17th level, you can use this feature twice.

Platinum Pinnacle

The spark of divinity within you has fully manifested.

Starting at 17th level, as an action, choose one dead creature within 30 feet that has been dead for no longer than one minute, and return it to life with 1 hit point. This feature can’t return to life a creature that has died of old age, nor can it restore any missing body parts.

You can expend any number of spirits as part of this action, restoring an additional amount of hit points to the target equal to half your demi-dragon level (rounded down) + your Charisma modifier (minimum 1) per spirit expended.

Once you have used this feature, you cannot do so again until you have finished a long rest.
