Primordial Dragonborn of Sound

This is it, this is the end of your journey... You have mastered the Llano and allowed it's changes to your soul, making you into a being of pure sound and energy. You have become a Primordial.

Your transformation grants you these abilities:

Prestige 2 (works everywhere):

Draconic Sound Manipulation:

Having mastery over sound, you increases your aura to 90ft (from 30). When the aura is in Inspiration mode, allies get a bonus of 3d12 (instead of the usual d12) to all checks, saves, and attacks. when in Healing mode, allies in the aura heal for 100 hit points (instead of 10) with excess healing becoming temporary hit points. You also benefit from these effects. The cost to use the aura drops to 1 charge of Bardic Inspiration and the aura lasts for 2 minutes instead of 1. While this aura is active, all saves that your spells force turn into Charisma saving throws and bypass condition immunities.

Wavelength Transfiguration:

Having become a Primordial of Sound, your form matches that. You have become pure sound and thus can change your frequency to change your form. You cannot physically age through any means, magical or not. You can use this ability like the spell shapechange a number of times equal to half your proficiency bonus, meaning you retain your spells, gear, intelligence, wisdom and charisma scores if you do choose to. Your form can change to:

Gold Greatwyrm
Ancient Gold Dragon
Ancient Titanium Dragon

You revert to your original form at the hit points in which you transfigured at if you drop to 0 hit points while under this ability. After this ability is used, there is a 1 minute cooldown before you can use it again

Prestige 4 (Works in native realm and realms where you have roots. Ex. Domain): 

Unprecedented Bass Boost:

Your music and sound can be heard throughout the realms as your domain over sound becomes unprecedented. All your spells that utilize Verbal components in their casting, have their range increased to half a mile (regardless of their original range). Additionally, a creature may utter your name in a limerick. Since your dominion is absolute, you are able to hear the pleas for help from the ones that utter your name and you are able to move at the speed of sound to their location by using your true form made of pure sound to shift and manipulate the waves of sound around you to get you to your destination.

Noise Ordinance:

As an action, you can pick a point within 120ft. and create a 69ft area of sound. When you use this ability you can choose to make the area have complete silence or make it so that every sound in it is amplified. While in complete silence, no sound can be heard other than your voice as your dominion over sound becomes apparent. Spells that are subtly cast become detectable by you and can be countered like normal spells. While in amplification, all sound created (even the sound of a heartbeat) within the area can be heard up to a distance of 200 ft. Your Psychic Scream deals double damage while this effect it active. This effect lasts for 10 minutes and can not be dispelled or until you choose to deactivate it as a Bonus Action. Additionally, you can place this ability on a small non-magical object that can be held in your hand (for example, a rock) and act as the center point to it.

Prestige 6 (Works in certain parts of the native realm):

Musical Aura:

Your musical aura can provide the verbal component of spells cast within a 60 ft. radius making it unnecessary for them to provide it in casting.

Lullaby:

If a creature takes a long rest inside of your domain, it can hear a sweet lullaby that puts it to a deep sleep. That creature regains all spell slots on a short rest.

Prestige 8 (works in domain or with explicit DM approval):

Rhythm of the Heart: 

You cannot read minds, but you can hear hearts. You always know a person's true feelings about something. Even the most trained and stone-cold hearts cannot hide themselves from you. The heart always betrays the brain and acts on its own after all...

Music Ambiance:

At the start of each day, you can choose a playlist of songs that can be heard throughout the realm like background music. The songs magically seem to match what a person is feeling at that moment and gives them an emotional boost should they need it. When they need to feel powerful, powerful music will play. When they need to calm down, calmer music will play and so on and so forth.
