A Sphere - BRV DMG is best (even a refined Kuja sphere is fine), but ATK is also great. Tons of options are open for this slot.
C Sphere - Focus on ATK or battery spheres. Her own or Sherlotta is fine for her, but certainly Alphinaud or Maria is best.
E Sphere - While Kefka or Seymour are premium for her, those belong on primary damage dealers. Avoid “Debuff Inflicting Spheres” (like Ultimecia or Vincent) at all costs, as the generic debuff is a waste of space.
Note that Arciela's crystal 54 passive is behaving oddly. Normally it should grant 20% ATK & 40% mBRV to the party, but in a full 3 ally party, it is granting 60% ATK & 120% mBRV. The infographic reflects this and more details can be found on Rem's Reddit post.
After using an HP attack and returning to 0 BRV (outside of mBRV Floor, BRV gains and BRV Retain effects) or being broken leaves you below iBRV. Normally it takes 5T to return to iBRV, but Arciela's Fast Cast buff speeds this up to 1T (so BRV emptied -> turn passes -> up to iBRV)
This was useful when she debuted but is obsolete now with how many ways there are to avoid being empty after turns
Arciela’s LD call debuff does not boost the caller’s HP damage, it just stops BRV gains
Arciela is a very flexible support debuffer hybrid that can round out any balanced party. She works in aggressive teams or trap teams the best as they can take advantage of her BT effect well without fear of enemy interruption
If wondering who provides an aggressive team more damage between Arciela, Weiss or Cissnei, Cissnei will win thanks to 6 AoE attacks. Weiss would also provide more damage than Arciela despite offering less true damage (Weiss: 10%, Arciela: 16%) because Weiss' linked attack benefits from all ally boosts as well
