Genshin 6.6 Stygian Onslaught - Dire Difficulty VI with unusual team comp

It appears that for each team, the 4th character rarely teams up with other three, but can be surprisingly good here. See team builds below: Team 1: C2R1 Mavuika C6R1 Bennett C2R1 Citlali C6R0 Ifa (Favonius weapon for recharge + pyro swirl & resistance shred + some healing + faster night soul triggering) Team 2: C6R1 Klee C2R1 Durin C2R1 Xilonen C1R0 Escoffier (Favonius weapon for recharge + freeze summon + some healing) Team 3: C6R1 Chiori C2R0 Columbina C6R0 Illuga C2R1 Yoimiya (fast recording of pyro damage)
