Celestial Healing Aura

Prerequisite: Must be a celestial being or be granted the spell by such as a boon by the Celestial inscribing a symbol into your body. 

Casting: The caster can either channel the equivalent of a 5th level spell slot thru their body (Celestial) or symbol (Non-Celestial) to activate the aura as an action or slowly charge it up over 10 minutes as a ritual. 

For the duration of the spell, life energy radiates from within you in an aura with the following effects:

• You heal a number of points equal to your spell modifier (minimum 1) at the start of each turn where your health is 0 or more.
• You heal a number of points equal to your spell modifier (minimum 1) at the start of each minute where your health is between (- 1/2 * Max Health)  and less than 0
• You heal a number of points equal to your spell modifier (minimum 1) at the start of each hour where your health is between (- Max Health)  and less than (- 1/2 * Max Health).
• Your body does not lose health nor can you be killed, even by a disintegrate, until your health is less than negative your max health as your body will constantly reform, even from dust. You will, however, enter a healing sleep if your health is less than 0.
• Optionally, instead of healing yourself or if you are at maximum health, you may use a bonus action to channel your life energy into up to your proficiency level of creatures within a 30 foot radius causing them to regain your spell modifier in hit points.
  • You do not need to see the creatures if you are familiar with them or have previously touched their auras as long as they are within 30' and you choose to let them draw upon your vitality.
  • Note that no one can force you to heal them, even through magic.
  • Channeling your celestial energy into undead and creatures from the lower planes or planes opposed to normal life will, instead of healing them, erode their bodies and life force doing the same amount of hit points as damage instead.
