[@ProPro] Only issues I see are some of the special trait namely his strength and the icy chill the wendigo brings. For strength, it needs to be dialed down significantly. At peak, I would accept being able to crush and cut solid rock with relative ease and on average I would accept something along the lines of crushing thick bones and cutting through tough hide. Those would be acceptable limits. As for the chill, get rid of it as a fatal power completely. You can keep it as cold air that leaves a thin layer of frost but not enough to kill people.
