Draconic Awakening

Using a bonus action you can transform into an ancient dragon the same type as your ancestry. You retain access to all your spells and your max HP is set to the ammount of that the dragon has in this form and you gain all the abilities from your dragon type. You will retain current damage but will not be at your current health. Instead subtract that damage number from the ancient dragon type's heath. The spell ends when it is manually dispelled or when you are reduced to 0 hp. When reduced to 0 hp you change back into your true form at 1hp saving you from death but you cannot transform again for an entire week if the spell ends in this way. If you dispell the spell normally you go back to your original health you had before you transformed (unless your current health is lower than what it was when you transformed in which case your health remains)
