Could you possibly clarify what stage in game you are at? Have you cleared maps, dungeons, journey?

When you said that you are limiting yourself to just 2 artifacts I assume that your main deck is probably not very strong - probably less than 10K-12k maybe? How far do you typically get through during the events?

After my alt(s) get to ~15-17k decks I could typically 5-star all artifacts. And on my main account I typically could finish the 15-th boss with 3 or 4 keys.

You see, artifacts are only valuable if you are going to use them, so I see two main scenarios here - using them until the end of the event with the light event deck or using them on your main deck afterwards.
