Ya, So I have ordered this but im wondering. I have started a new game again basically because Windows took a dump and I lost everything so, I was going to play into it but im waiting for KOTN to be delivered in a couple of days so does it matter how far you have progressed already in Oblivion? I don't want to miss anything at the start or anything that KOTN has? The new armor in it looks ace.

It's a levelled questline, like most of the others in Oblivion.

You can technically do it at level 1, but the enchantments on the armor will be crap compared to later levels.

Ya but even if you do get the armor as you level up it gets better no?

I would think that the armor would be the same no matter what level you got it at... anyways, I just got KOTN today, I'm so happy

Each item that is from a quest has different levels depending on what level you are, kind of like the sigil stones, you have level 1 items, then 5,9,13,17 (and possibly 25 but i'm not sure on that one) so as long as you are at least level 17 you should get the best armor and other enchanted items you get from that quest (unless there is a level 25 item, then youl obviosly have to be 25).
