Boon of the Eternal Spirit

You are immune to any effect that would reduce your ability scores, as well as any effect that would instantly kill you. In addition, you can cast True Resurrection as an action without using a spell slot or any components.

Once you cast this spell, you can't cast it again until 7 days have passed.

If you die while being able to cast this spell, you are restored to life as per the True Resurrection spell after three days in a location of your choice on the same plane of existence which you were slain. This does not count as you casting True Resurrection.
