Amulet of Angelic Aether

Born with a divine spark Aasimar can tap into the celestial magic of the upper planes. Unfortunately, they can only use so much heavenly power. However, by attuning to this amulet, they can fully ignite the divine spark within, unlocking their true angelic potential and manifesting as the celestial being tied to their bloodline. As a magical action, the wearer can cast a special version of True Polymorph on themselves, transforming into an angel of their choice regardless of Challenge Rating (CR). Unlike the standard spell, this transformation does not require concentration, only physical contact with the amulet. Alternatively, the user can roll a 1d4 to randomly determine their angelic form. Regardless of the chosen form, the wearer retains their own equipment and does not gain the weapons of the angelic form but may use any abilities that affect their own weapons and items. Once the transformation has been completed the amulet requires an amount of days equal to the CR level of the celestial you took the form of to recharge. This amulet can also be used as a holy or spell casting focus. 

The type of angel chosen or rolled determines the duration of the transformation:

1: Become any celestial with a CR below 10. Transformation lasts for 1 hour.
2: Become a Deva. Transformation lasts for 45 minutes.
3: Become a Planetar. Transformation lasts for 30 minutes.
4: Become a Solar. Transformation lasts for 15 minutes.
