The idea is a set of artifacts that form a set (and can either combine ect.. once you have all of them). In either case when you get the whole set they all can be used to get a bigger boost or some other effect.

This could also be a way to add another route to get modules as you pick up the parts (which would likely have some fuction on there own).

New types of terraformers, bigger short time statboosters, ect...

i like this idea, like taking some stat boosting artifacts, combining them with an npc drop and "upgrading" the drop item to a better one(if there is one, like upgrading a auto laser to a blast phaser by combining it with some crimson ob's, some kurenite and a chunk of credits) or creating a different item all together...give us a chance to do something with extra npc loot that we can't install or use but dont wanna scrap cause of the effort it took to get them
