Oblivion Artifact Pack SE is a mod that brings back many of the classic unique weapons, armor and clothing from The Elder Scrolls IV: Oblivion.
The most obvious change is that these items are now much easier to find, as most of them have been moved to the main location, and some have even been redesigned to be more useful in the current environment.
But there are other changes that are less obvious, but just as important. The most significant change is that a lot of the items that were previously in the Glacial Cave have been moved, so that they are no longer outside of the borders.
