Chromaversy

"As the Aetherborne are born from stardust and the chaotic magic of all planes and the weave itself they have a natural affinity towards magic and the manipulation of it. Whether it be turning a fireball into a thunderous explosion or manipulating a series of fiery rays to inflict an acidic burn upon their target, chromaversy is the art of taking the matter of the universe and altering it to the casters liking.

Something of great note is that though I have never seen one with my own eyes I have heard tale of beings that have descended from the stars and saved entire civilizations or damned them to oblivion and because these casters are particular to the Aetherborne an already rare race I believe these Chromancers must only appear once every few millennia." —Archmage Albazarr

When you cast such a spell you deal additional damage equal to your level in this class + your charisma modifier.

Manipulate Matter

Once you advance to 6th level, you gain further control over the matter that makes up the universe and begin to pull from the outer planes such as Mechanus the plane of order and control, and in doing so you learn how to manipulate your spellcasting. When casting a spell which deals damage you may change its damage type to another type which you have an affinity for this may be achieved by spending sorcery points equal to the level of the spell.

Planar Explosion

Upon reaching 14th level, you learn to feed your magic with the essence you're made from when casting a spell with which you have an affinity towards you may spend 2 sorcery points to deal an additional D10 damage this damage may be chosen from any type you're resistant towards, furthermore, you may spend one additional point to add an additional D10 up to 5D10 damage.

Universal Being

Beginning at 18th level, you have achieved what all Aetherborne strive to achieve over the course of their lives. By expending 5 sorcery points and a bonus action you may enter your transcended form, gaining resistance to all damage types listed in the Planar Form feature granted to you at level 1, furthermore, your flying speed now equals The Aetherbornes base speed times your intelligence modifier and lastly spells that deal damage of a type you have an affinity towards now reroll the lower half of there damage.

This form lasts for one minute and can only be used once per long rest.
