I could be interested in this. I have a couple ideas for artifact hunters:

A snake-beastman artifact hunter that is kind of like a ninja, and has snake/poison themed abilities and artifact.

An artifact hunter that's totally insane and thinks artifact are remnants of the gods that he can use to communicate with them. Totally off his nut but is surprisingly competent and has weird artifacts that only he can figure out for some reason.

Thoughts?
