Did you read the post regarding the final?
Yes I read it, but it didn't say anything about healing magic being used to restore them, only rest. I chose to assume they'd be barred from outside restorative spells in the interest of fairness, and because given the tournament to that point, I think it's more interesting. If they're both completely fresh, honestly, Shale would crush Sten like a bug, just like any other conventional warrior. It takes cumulative damage or something like the mages to bring down a golem, unless you're talking about something bigger and meaner like a dragon. Speaking for lore, or realistically. My vote went to Sten because I see him as taking less of a beating to that point, Shale being softened to a point that Sten's swordsmanship would even be a factor. At that point, Sten's more skilled, and Shale can't effectively counter him, so Sten wins.
edit: To clarify, the injuries I mentioned are the only ones I see them taking in the tournament. Those are also where they should've lost if I were judging. I think the other matches are not-a-scratch type victories, mostly.
