Imaginarium Theater [September 2026] Walkthrough & Guide A thread! 🧵
- #2
Act 1 Pick the Electro-Charged buff and keep spamming it It should be trivial for Cyno + Xingqiu with buff level 2 as long as you group enemies properly Only pick the Hydro Abyss Mage stage if you have a lot of Dendro application You can check Act 9 for the way to group them
- #3
Act 2 I think both stages are somewhat equally easy But here I chose the Saurian stage as it's easier to group enemies The Anemo Machines move a lot so it can be difficult to group, just stun them when they charge into you Electro-Charged can be spammed here with Hyperbloom
- #4
Act 3: Jadeplume Terrorshroom Filling the gauge with Electro makes the boss perform an attack and get stunned (with bad RNG it may run around, you can retry in that case) Deal as much damage as possible when it's stunned Electro-Charged spam should work just fine with Lauma
- #5
Act 4 I think the Hydro Slime stage is easier as you can shoot down the Ruin Guard while spamming Electro-Charged to paralyse the Hydro Slimes easily If you struggle, consider using taunt characters like Alyosha/Tighnari, they work really well Be careful of Bloom and Burning dmg!
- #6
Arcana Challenge 1 Use strong AoE teams (Neuvilette, Sandrone,...) to defeat enemies on time and a teamwide healer to survive the HP drain Shield has disadvantage You can try budget Bloom team like this! In that case, I'd recommend to get at least Bloom buff level 2 (extra core!)
- #7
Act 5 Just DPS check You can spam a lot of Electro-Charged and Hyperbloom on to get past both stages, I think they are equally easy The Big Rifthound is tanky but it's easier to group and kill the small ones And here's how to group the Ruin Machines if you wanna do this stage
- #8
Act 6: Emperor Crab It has Pyro shield which increases RES, and can be broken easier with Hydro You can spam Electro-Charged to break the shield Make sure you aim for the horn on its head if possible, that's where the shield is You can reach the horn easily in the eruption attack
- #9
Act 7 You should avoid the Wilderness Hunter stage: it needs Ascedant Gleam and we should save the Nod Krai characters for harder stages The Fatui agents stage has no requirement so with enough DPS you can pass it with literally anything, including Electro-Charged spam
- #10
Act 8: Battle-Hardered Pipilpan Idol It will hide in a hat and shield up Find the real hat like this by looking for the golden trail The real hat also has eyes Spam Electro-Charged/ Lunar-Charged to break the shield easily With enough DPS this should be trivial!
- #11
Arcana Challenge 2: Battle-Harderned Vishap Periodically, it will spawn a shield and a surrounding field which continuously drain your active character energy I recommend bringing good Dendro application to break the shield, especially ranged (Collei/ Tighnari works really well)
- #12
Act 9 Focus on the bounty target as always If you have good Dendro application, go for the Hydro Mages If you have good Hydro application, go for the Pyro Mages Here's how to group them easily You can also use Hydro slimes to spawn more Dendro Cores, further damaging the Mages
- #13
Act 10: Radiant Moonfly After a while the boss will apply a debuff which significantly reduces your damage dealt Bring a good healer to remove the debuff Barbara can remove the debuff instantly with her burst Pick all the necessary buffs Bring your best team to clear on-time!

Please note that this is just a reference, you should adjust your strategy accordingly based on your investment Kokomi, Sandrone are C0R0 Nilou is C1R0 (cons from the To Temper Thyself and Journey Far event) The borrowed Flins is C0R1 Good luck clearing everyone! :D
