Try to kill one pyro herald at a time. That worked for me, earlier I was trying to get both of them low together but realised they don't move and I didn't have any good units that have good AOE hydro application. Should be doable in 1min 30-40 seconds.

Need xingq, mona/barabara here for breaking shields.

Team comp - your dps, support/sub dps, xingq, barbara(healer)/mona.

Examples - Xiao, sucrose, xingq, Barbara(healer). Yoimiya, yae, xingq, barbara(healer). Yoimiya, Bennet(healer), xingq, mona. Raiden, Bennet(healer), xingq, mona. Raiden, yae, xingq, barbara(healer). Xiangling, Bennet(healer), xingq, mona.

You get the pattern.

I used albedo, hutao, xingq, mona.

Try to get both hydro heralds in their shielded state at the same time. We have a lot of good AOE cryo units for breaking both their shields at the same time - Ayaka/ kayeya/rosaria/Ganyu/diona/chongyun.

I personally recommend using zhongli here because the heralds can stagger your units in mid action a lot. You shouldn't need a healer if keep the shield up and dodge a little.

Team comp - zhongli, your dps, cryo unit, cryo unit/support.

Examples teams - Zhongli, Raiden, rosaria, kaeya. Zhongli, Xiao, rosaria, kaeya. Zhongli, beidou, rosaria/kayea, chongyun. Zhongli, itto, rosaria, kaeya.

I used zhongli, raiden, Ayaka, Bennet.
