Teams I used for Challenges 1-4.
1-1: Eremite mooks + elites. Anything with suction will do. I used Thoma Burgeon with Venti flex so I could use stronger teams for other floors, but National variants, Freeze or Raiden Hyper should also do well.
1-2: Hilichurl mooks, just blew them up with Rational.
1-3: Slimes and Geovishaps. Used Freeze because Geovishaps are annoying but frankly they’re weak af.
2-1: Eremite elites and Fatui. The elite enemies on this floor cast hazards, and some of them have earthquake so watch your step. Not much trouble, Freeze was fine for grouping and lockdown.
2-2: Electro hilichurls and mages. Trash mob floor. International mopped them up.
2-3: Geo hilichurls. Bring somebody with a shield to get some extra damage from the buff. Shield mitachurls are annoying so you’ll probably want someone who can pierce like Nahida or Yelan, but anyone else you want will do okay here. Keqing Aggravate was comfy so I just ran that.
3-1: Oops, all Hydro Mimics! Quickbloom blows this whole floor apart so you really only need one EM Electro + Dendro driver. I brought Kuki and Alhaitham for those roles, with Beidou for extra damage and Yaoyao as a panic heal.
3-2: 2 waves of Eremites, followed by Dendro Tiger + Electro Scorpion. Fuck these guys. Freeze locks them down but you need a lot of investment/good rotations with cooperative grouping to kill them in time. National might work if you never ever get hit by the scorpion, because if that shithead even scratches your character they’ll be flying over to Celestia.
3-3: Eremites and Primal Doritos. Uhh bring Quicken, whatever.
4-1: Hilichurl Rogues + hilimooks. Freeze was good for lockdown but this is fairly straightforward for any team.
4-2: Ruin bots, Kequeen delivered again. Bring anybody decent, focus down the doritos first and you’re good.
4-3: Fungi and Cryo whoppers. Venti is wonderful but these weeds are obscenely tanky. International works here, note that Childe’s bow burst can reliably hit inside Venti’s burst and refunds energy, which is good for secure rotations. Be careful when the whoppers spawn since Reverse Melt + obscenely boosted attack can get one of your teammates killed easily.
Back with Challenge 5 done. Imgur is saying it’s 18+, idk. A rather underwhelming finale, though I suppose that’s easier for less invested players to break into.
Character builds here.
5-1: Pyro hilichurls, Pyro slimes, Pyro spectres, and a Dendro samachurl. Lots of mooks and you get a +30% ATK buff, so bring characters that scale with ATK. I went with Quickbloom but Hydro/Cryo heavy teams will do well in general.
5-2: Electro slimes plus Cryo slimes, spectres, and whoppers. A potent Swirl buff is added so Pyro + Anemo anything (excluding Traveler, who prioritizes Cryo absorption) crushes this floor. I went with an Air Fryer variant. National with Sucrose should also be fine.
5-3: Treasure hoarders and Fatui? What is this, the VV artifact domain? You get another Swirl buff and every enemy on this floor is weak to Venti, so there isn’t much to discuss.
