Today, we bring you the guide for Version 6.1's Imaginarium Theater. This version also introduces the higher difficulty "Lunar Mode", needing 28-32 characters with 12 combat acts. Compared to "Excellence Mode", it requires 6 more characters but offers an extra 200 Primogems as regular rewards, plus a 300 Primogems initial reward upon completion.
The Imaginarium Theater is among Genshin Impact's most thrilling seasonal challenges, combining unique mechanics, rotating elemental restrictions, and a well - selected cast. Success relies on understanding seasonal rules, using elemental reactions well, and making smart team - building choices with limited rosters. In this guide, we'll cover essential strategies, boss mechanics, and character recommendations to help you master each act, whether for smooth clears or high scores, maximizing your roster's potential.

Act highlights & Boss tactics
Act 3
|
Maguu Kenki |
|||
|
Since long-range skills are often deflected or parried, staying close with strong shielding is actually the most efficient approach. With protection and consistent melee damage, the Maguu Kenki fight becomes straightforward and fast to clear. Tip: Any main DPS character will work. |

Act 6
|
Battle-Hardened Primordial Bathysmal Vishap |
|||
|
A Vishap will unleash a Cleansing Shower attack that strips Elemental Burst energy from any character hit. If the character doesn’t have enough energy, the attack will instead consume their HP, creating a constant pressure to stay healed and avoid repeated hits. Tip: Be sure to include a Dendro character, as they’re essential for breaking Hydro shields. |

Act 8
|
Knuckle Duckle |
|||
|
Knuckle Duckle can enter Duckstruction Mode, becoming more aggressive and summoning Stamping Devices. Using Electro-Charged or Lunar-Charged reactions on these devices will make them attack Knuckle Duckle instead. Be cautious of its slam attacks. The boss always retracts its arms before leaping into the air, signaling its next strike. Tip: Bring Hydro and Electro units to use Electro-Charged and break the shield. |

Act 10
|
Emperor of Fire and Iron |
|||
|
The Emperor of Fire and Iron boss is vulnerable at its two Pyro-infused horns. When these horns are near the ground, you should use elemental reactions, preferably using Hydro, to quickly destroy its shield and also slow down its attacks. Tip: First break the Pyro shield, then unleash full damage. |

Lunar Mode: Arcana Challenges
Arcana Challenge 1
|
Shadowy Husk: Standard Bearer |
Shadowy Husk: Line Breaker |
Shadowy Husk: Defender |
|||
|
Keep battling until the countdown finishes. To successfully complete the challenge, you need to end the stage with at least one character still alive. Every opponent you defeat will reduce the remaining countdown time. Once the challenge begins, all party members will continuously lose small amounts of HP. Tip: Entering the battle will continuously drain your HP, so it's best to bring a healer. Avoid using shields, as the boss will become enraged if it hits them. |

Arcana Challenge 2
|
Perpetual Mechanical Array |
|||
|
The Perpetual Mechanical Array summons four Ruin Machines (only one is targetable) either when the fight takes too long or when its HP drops below 50%. To defeat the boss quickly, immediately reduce its health past the halfway point to trigger the summon phase. Once you defeat the single targetable machine, unleash your burst attacks to finish off the boss entirely. Tip: Just ensure your damage is high enough. Make full use of buffs to maximize your output. |
