This mod is your tradiontal treasure hunt mod. It adds various powerful or otherwise semi-useful weapons and armors, and places them in random locations throughout Vvardenfell.
Except there's a twist. All of the artifacts suffer from 'Object duality', in other words, they look like something useless or otherwise innocent until you pick them up. Some might be a broom, or a bottle. Either way, you'll never know if that fork sitting on a table is a giant world-warping sword or just a fork unless you pick it up of course.
The mod changes almost nothing, and is compatiable with nearly all mods.
