I have a PC who gave the idea of "taking damage from healing". Essentially her character would take part of the damage that another character took, which would then be added to her image after she performed any healing of any sort.
I.e. if she heals a Barbarian who took a sword wound to the chest, she would heal the damage but take partial damage and form a scar/wound wherever the wound was on the barbarian. It would mostly be used for RP reasons but I want to make sure I have a good rule set for combat with it.
If there is any pre-existing conditions that has information on this, that would be awesome to know. I might need to create an archetype or specific curse that outlines it better if not. Any ideas or help creating this would be awesome!
