Although it is easy enough to go and do this quest with a high level character, I noticed that the difference between not completing "Siege of Harrogath" and completing it does not correctly trigger the Larzuk reward (using the editor.) It would probably be best to break that option out into a "Consumed reward" part.
I'm going to try and provide screenshots and the D2S files of a character where I tried to record for you to be able to determine the differences.
