I’d suggest prioritize getting more defense blessings than offense

While DU does seem to be Firefly’s domain, if you’re struggling with threshold 6 without her team then you’d need to prioritize survivability than “to kill or be killed” strat. It’s actually possible to finish the final boss while barely getting any scratches. I tried my DoT team and while they’re only doing average of 1 million dmg (compare to my Firefly team with average 3 million dmg), they still able to comfortably beat the boss.
Additionally, you’d also want more remembrance blessings even without characters like March or Misha. Not only it will stall the enemies, there’s also an equation that burst all dmg received by the enemies when freeze/disassociation is removed.
