Godwalking shouldn't be an issue for PCs, but is achieved through Trans-Superb skill levels. Statistics also have inherent value, aside from enabling skills. Body is the basis for wounds. For each step below Fair, remove a wound, starting with Flesh Wound, then a Hurt, and so on. In theory, a body ten steps below Fair has no health levels, but then a body that low shouldn't be biologically feasible in the first place.
Wounded characters get pain penalties.
Near Dead and Very Hurt characters will heal a health level from every severity once a month. Hurt characters heal once a week. A character with nothing but Flesh Wounds heals daily. Speed is used for initiative. Mind is used to keep from freaking out at bad moments.
