Artifact weapons and armor in Skyrim almost always underperform, and some vanilla items are better than the famous rare ones. Here is the solution to this dilemma! The Zim’s Artifact mod changes the stats of most unique weapons and armor sets in the game in a balanced manner.
These items will not be overpowered, but at the same time will serve you much better than vanilla items. This will make your character have both a unique look, and be strong enough to deal with most threats.
