You wake up in the body of an angel, a powerful being of divine energy. While your true form is inscrutable to being of lesser power, you instead appear as a humanoid with a pair of feathered wings. Your exact appearance is malleable to a degree. All angels are timeless, you do not age.
As a divine being, you have natural proficiency with any divine or spiritual magic or powers as well as a significantly greater well of power to draw from. In addition to this, you have 150 years of experience to distribute between any of your powers that increase in strength with skill. Due to their nature, your powers are more effective against devils.
When assuming a physical form, you are able to contest an adult dragon for strength and toughness in a much smaller package.
