This skill heals major wounds. Not only does it heal more HP damage than First Aid, it can also restore a crippled limb to full health. Like the First Aid skill, it can only be used successfully a few times a day. If all the uses of one of the healing skills are used up, it is still possible to use the other healing skill until it runs out of uses as well. Using this skill will advance the game clock by several hours. Using a Doctor's Bag will increase your chance of successfully using this skill.
