Once again I tackle fearless mode! Al Haitham is quite good, even though he's not an "exhalted one". Who needs this anyways lmao. Second enemy I opted for a f2p Varesa with 4* Teammates, Standard Weapon. Some of my 4* are c6 though. If you don't have a 5* Weapon, you can try your luck with the Widsith! Just get prepared to reset a lot. Third chamber I ended up using Neuvillette, he holds Sacrificial Jade. For the gauge mode of the boss I used Escoffier and Skirk, who can adjust her rotation to what is needed at the moment. If you don't have Skirk you may need triple Cryo for him to do damage.

Teams: Mavuika, Chevreuse, Iansan, Ororon; Arlecchino, Bennett, Xiangling, Kaedehara Kazuha; Skirk, Furina, Yelan, Escoffier;
