Aye, so the item choices are lacking pretty hard (I'm using the item mod on the workshop but neither is it updated, nor does it do what I want to describe here ^^). If I had the skills and the patience, I would do it myself. So here's an idea for whoever can get excited about the idea and thinks "Yeah, that sounds cool, I want that!";

A collection of artifact items. Lots of them, for all kinds of aspect and gameplay combinations that are rare and can be found, even if rarely. I don't know if it's possible, but maybe restricting the respective artifacts the player can drop by script to fit their chosen aspect path (Main aspect + maybe the second highest aspect value, or a third one too?).

I think it'd be cool if they weren't OP items, but strong items that can change the way something works or something to that effect. Something clever.
