I want to share my experience on this CQ.
So short story, I broke bar all the servant in this CQ (Nobu full HP, Jarcer full HP , Taiga 35k HP). All my servant dead, except Dantes who is buffed with Skadi + Waver, which should be enough to clear in one NP.
I attacked Nobu so I can charge NP and prevent Jarcher get water field. Somehow all my attacks crit and kill Nobu. Taiga NP Dantes, and he survived by the 1 HP gut with full NP charge.
So by this point, the field should be Burn & Forest because I attacked Nobu, but because Nobu is dead, somehow Taiga is having Forest & Water field.
So, what I can learn from this. Make sure the one who has field buff isn’t dead yet, or the most right position will have the field buff.
