You have linked your soul to two creatures: A great Archmage, and an Aspect of Bahamut.
An aspect of the Platinum Dragon now burns within you. Once per long rest, you may use one of the following Actions.
Exalting Breath. You exhale the restoring winds of Mount Celestia in a 300-foot cone. Each creature in that area of your choice regains 13d10 hit points. The breath burns of pure goodness. For as long as your alignment is any other than Lawful Good, you take half the healing as Radiant Damage.
Platinum Breath. You exhales radiant platinum flames in a 300-foot cone. Each creature in that area must make a DC 26 Dexterity saving throw, taking 12d10 Radiant Damage on a failed save, or half as much damage on a successful one. The breath burns of pure goodness. For as long as your alignment is any other than Lawful Good, you take half the damage as well.
Legendary Resistance. You gain 1 Legendary Resistance per Long Rest at the cost of taking 10d10 Radiant Damage if used.
The knowledge of a great mage now resides within you. You gain the following traits.
Languages of Lost. You can speak, read, write, and understand any language that can be considered a language.
Fetish. By spending 8 hours of concentration, you may imbue an object that is dear to you with a piece of your soul, creating a Fetish object. You may only have one Fetish object at a time. If you are killed, the entirety of your soul is transferred to your Fetish object. Your consciousness remains, and you may spend 1 hour focusing to return your soul to any body within 1 mile that does not currently contain a soul. If your Fetish object is destroyed while you are inside it, you are immediately killed. If your fetish object is destroyed while you are still alive, you immediately drop to 0 HP and are considered stabilized, and lose your Fetish object and must create a new one.
Knowledge of Mystra. Once per long rest when preparing spells, you may select one spell up to a level you can cast that is on any spell list, and prepare it for that day. The spell requirements remain the same, but it may be cast a single time that day without expending a spell slot. If the spell is not used, it is lost at long rest and must be chosen again when preparing spells the next day.
