Stellar Vibes

You have a natural affinity for the stars that exceeds that of even most Astral Elves. They align for you often and conspicuously, and as such, you can call upon their power to both sense what is about to happen through a Portent of the Stars and trade places with another in dire circumstances when that foresight isn't enough to save to save you from the fire. Another side effect of your affinity is the ability to produce a stellar aura that heals others within 20ft once a day.

Portent of the Stars. As a reaction when a creature you can see within 60 feet of you makes an attack roll, saving throw, or ability check, you make that creature roll [roll]1d10[/roll] and add or subtract the number rolled (your choice) from the roll. Once used, it cannot be used again until the next dawn. Your connection with the uncertain future also grants the cantrip Guidance.

Stellar Aura. Healing energy radiates from you in an aura with a 20-foot radius for 1 minute. Until the spell ends, the aura moves with you, centered on you. You can use a bonus action to cause one creature in the aura (including you) to regain [roll]2d6[/roll] hit points.
