No skill can ever be higher than the parent statistic. This should result in the character having a few skills that are good enough to define them, and a lot of tinkered skills. One of these skills is chosen as the character's obsession skill. For Avatar skills, the first channel is available at Mediocre skill, the second at Good, the third at Great, and the fourth at Superb. 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.
