I am considering adding a house rule to my Pathfinder campaigns to allow a character with ranks in the “healing” skill to be able to apply healing to wounded characters up to their total heal skill per day, with no more than their level going to any single character per day.
Huh, turns out that there is a “treat deadly wounds” ability that can heal a wounded character using the heal skill. It cures hit points up to the character’s level but requires two heal kit uses. Which seems reasonable. You have to make a heal check with a DC of 20. If you beat it by 5 or more you can add your wisdom bonus to the healing.
