True Form

As a half angel, you can call on your ancestors to temporarily relieve you of a mortal body.  Once every long rest, you can call upon your ancestors and reach your true angelic form.  During these 3 minutes, you gain the following benefits:

• You become resistant to bludgeoning, slashing and piercing non-magical attacks
• You gain advantage on saving throws against magical attacks, except necromancy
• You are immune to being charmed, frightened or otherwise mentally incapacitated
• You cannot be exhausted
• You get advantage on charisma and dexterity checks

This effect ends if you are knocked unconscious or are attacked with a necromancy based spell.
