My current party is challenging my mastery of the healing rules more than any group in 40 years. Specifically right now, a character received a burn crit that specifies "massive tissue damage" and "limb useless." Two other characters are healed of damage but have scarring over most of their bodies. I've pored over my RM2 books, and checked for guidance from the RMSS books, but there is an inconsistency in the description of injuries and their types, and the spells for healing. Crits and the injury recovery tables include a category for "tissue" distinct from "muscle/tendon." In RMSS the former becomes "skin/tissue," confirming the suggested meaning that's never spelled out. But there are no spells in RM2, or even that I could find in RMSS, for healing tissue damage. Bone, organ, muscle, blood and "surface" are the categories. Surface includes burn relief which could be used for either of these, I suppose. The first character could require Burn relief III to heal that leg of 3rd degree burns, and the other two could require Burn relief II to heal their whole bodies of 2nd degree burns ("one area" = whole body?)
Has anyone else run into this and found a better solution? What about tissue damage that's not burn or frostbite?
