Heh. If it wasn't Tuesday night, I would have already signed up. I love playing clerics.

For your group, though, I would recommend what has already been said -- boost up the Alchemy and Herbalism skills a bit by introducing a healing item.
"This poultice will help your friend a bit... It takes three leaves of Mugroot -- make sure they're fresh! -- a bit of leech, and some mistletoe. Apply it to the wound. It speeds up healing, but it leaves the body exhausted."
Or in other words, it converts a certain amount of real damage to subdual damage. And it requires a Knowledge: Nature or Profession: Herbalism check of DC whatever to find the components and will take X number of checks (Profession: Herbalism or Alchemy) to create.
Just a thought.
