I think you are better farming the marechausse hunter set and you will be getting furina s artifacts in the process .. and you can add katchina to the party (it will boost the damage by 40% for noelle and furina or any element used to trigger her reaction)
If you plan on farming for artifacts, I think its a good idea to spend some time to unlock the Marechaussee domain in Fontaine so you can farm for both Noelle and Furina at the same time.
