Does the spell of immortality completely heal Demona and MacBeths injuries. Do bullet or stab wounds heal without a trace or do the leave battle scars. It had occured to me that the spell might not have to heal them to be good as new, just enough to keep them alive. If being "alive" is the minmal requirement. Then the two of the could theoretically go into comas for the rest of eternity and still be considered "alive" for the purposes of the spell. I know, now way you were actually going to do this. Just exorcising a "creativity demon."
