Angel's might

You manifest the angelic powers within you, gaining access to power that was once lost. In order to gain this feat you must be at least level 8, and have the Celestial creature type.

While you have this feat your fly speed if you have any becomes 60ft per round.  Further more, all Fiends, Undead and Celestials within 60ft know you are an Angel and will act accordingly. Alternatively this can be corrupted and give off a chilling orea rather than a Holy one. This is based on your alignment.

• Angelic Weapons: As an Angel your weapons attacks are magical. When you hit with any weapon, the weapon deals an extra 1d8 radiant damage (This increases to 2d8 at 15th level, 3d8 at 20th level) These dice do NOT double on Critical hits.
• Magic Resistance: You have advantage on saving throws against spells and other magical effects.
• At level 15 You gain telepathy with a range of 60ft, the creature must speak a language you know. Also your Darkvision increases to 120ft and you gain blindsense of 10ft.
