I went into like 5 dungeons (cleared) and completed like...four main quests I think?
You know what, you might be right. There MAY be items that don't scale. I'm just saying that there are definite tiers of items, enchants to attach to items, and the like. I have found about four items that are named, none of which seem to be "strong for my level" if you get what I mean.
I may be wrong, and I hope I am, but I cleared this pretty dang hard dungeon, got a unique bow, and it was BARELY better than the "tiered" equivalent of what I already owned from a shop.
