User blog comment:Sneak+stab/50%+60% is not 110%/@comment-4644719-20111214132222

I've heard in the chatrooms that the resistance might be for the secondary effect only, so it would reduce the secondary burn damage of fire, the stamina damage of cold, and the magic damage of shock. This is easily testable, by sticking my face in the impassably windy part of the Throat of the World with and without resistance and comparing.

That said, I'd like a pretty radical amount of frost resist before I try that, in the range of 50-60%. That way, the difference will be obvious.
