[Rq-rules] Re: Heal and xenoheal

[Guy Hoyle]

It might be interesting (and not too hard to implement) if people and 
animals healed by magic built up a resistance to healing magic. Perhaps 
(for example) for every x points of magical healing in a 24-hour period, 
they built up 1 point of healing resistance. One point of healing 
resistance wears off after 24 hours without magical healing, but it 
blocks 1 point of healing. That's just off the top of my head.
