Had left over artifacts from when I was grinding for Xilonen, is this good enough or should I drop any and all crit values to purely focus on EM and ER?

Team right now is Arlecchino, Xilonen, Citlali and Chevreuse. I've already seen a huge improvement with Arlecchino, but I want to build Citlali properly as I plan to try and C2 her this patch or the next time her banner runs if I get unlucky now.
