How would it work if someone wearing the Pallid Crystal was hit by an inflict spell by an Oracle with the bleeding wounds Oracle revelation from the Bones mystery? Assume that the wearer is a worshiper of Urgathoa. The Pallid crystal causes inflict spells to heal the wearer and the bleeding wounds revelation causes inflict spells to cause bleed damage. The bleed damage can be stopped with any effect that heals damage. So does the wearer take the bleed damage as normal, is it stopped before it starts, or does the turn the bleed damage into fast healing? I doubt it's the last one but I was trying to cover all possibilities.
