Dragon's Dramatic Awakening

This spell transforms you into a powerful dragon, which lasts for the duration, or until you drop to 0 hit points or die. The new form can be any dragon whose challenge rating is equal to or less than your sorcerer level. Your game statistics, including mental ability scores, are replaced by the statistics of the chosen Dragon. You are limited in the actions you can perform by the nature of your new form. If the chosen form has Legendary Actions, Legendary Resistances, or Layer Actions, you do not gain access to those features. You can't cast spells, use items or objects, or take any other action that requires hands unless specified by the DM. If your new form can speak, you may speak the languages the new form knows only if you are concentrating on the spell. You retain your alignment and personality only while concentrating on the spell.

Your gear melds into the new form. You can't activate, use, wield, or otherwise benefit from any of your equipment. You assume the hit points of the new form. When you revert to your normal form, you return to the number of hit points you had before you transformed. If you revert as a result of dropping to 0 hit points, any excess damage carries over to your normal form. As long as the excess damage doesn't reduce your normal form to 0 hit points, you aren't knocked unconscious.

If you lose concentration on this spell, you don't revert to your original form. You instead go into a frenzy and attack the nearest conscious creature you can see each round. If the form you chose has multiple types of attacks, you may choose which attacks to use as normal, including breath weapons. At the end of each turn, if you attacked or otherwise harmed an ally, or there are no conscious creatures within your reach, you may make another concentration check against your spell save DC. If you succeed the saving throw, you regain concentration on the spell and control of your draconic form.

Casting at Higher Levels: If you cast this spell at 6th level or higher, you have advantage on your concentration checks, and your maximum duration raises to 10 minutes. If you cast this spell at 8th level or higher, you don't have to make concentration checks to maintain the spell, and your maximum duration is raised to 1 hour.
