The January 2026 Imaginarium Theater Luna III rotation restricts players to Pyro, Hydro, and Electro elements while presenting Level 90-100 bosses across ten acts. You'll need 28-32 Level 70 characters for Lunar Mode, with specific counters for Perpetual Mechanical Array, Emperor of Fire and Iron, Knuckle Duckle, and Maguu Kenki.
January 2026 Overview
Luna III introduces strict elemental restrictions—Pyro, Hydro, and Electro only. No Cryo, Anemo, Geo, or Dendro characters allowed. This limits reactions to Vaporize, Electro-Charged, and Overloaded.

Electro-Charged Blessing: Boosts Electro-Charged damage by 250% and Lunar-Charged damage by 70% for 3 seconds.
Overloaded Blessing: Applies Embrittled status, reducing Pyro/Electro resistance by 5.5% per stack (max 4 stacks = 22% reduction) for 12 seconds.
Fantastical Blessing: Universal 20% boost to HP, ATK, and DEF.

Theater Mechanics
Vigor Management
Each character enters with 2 Vigor stacks. Deploy strategically—reserve strongest characters for Acts 8 and 10 (Level 95 and 100 enemies). Early acts use weaker characters.
Blessing Selection
Match blessings to team composition:
Vaporize teams: Vaporize Blessing
Fischl + Xingqiu: Electro-Charged Blessing
Xiangling + Fischl: Overloaded Blessing
Uncertain: Fantastical Blessing
Star Challenges
Optional objectives awarding medals. Common types:
Time limits
Reaction count requirements
Mechanical constraints
Acts 8 and 10 offer highest medal efficiency.
Act 3: Perpetual Mechanical Array (Level 90)
Enemy Analysis
At 50% HP, boss summons 4 Ruin Sentinels. Damage any marked sentinel to stun the boss, creating extended damage windows. Reserve bursts for stun phase.
Attack Patterns: Laser beams, ground slams, spinning attacks. Predictable sequence allows constant DPS with proper positioning.
Premium Teams
Raiden Hypercarry: Raiden + Xingqiu + Fischl + flex Hu Tao Vaporize: Hu Tao + Xingqiu + Yelan + flex Yoimiya Ranged: Yoimiya + Xingqiu + Fischl + Bennett
Budget Clear
Team: Xiangling, Xingqiu, Fischl, Bennett
Rotation: Bennett burst → Xingqiu skill/burst → Fischl skill → Xiangling burst → normal attacks in Bennett circle
Investment:
Xiangling: Level 80/90, 8/8/8 talents, 4pc Emblem, 60/120 Crit, 180% ER
Xingqiu: Level 80/90, 8/8/8 talents, 4pc Emblem, 60/120 Crit, 180% ER
Fischl: Level 70/80, 6/6/6 talents, 2pc combos, ATK%/Electro DMG/Crit
Bennett: Level 70/80, burst talent 8, 4pc Noblesse, ER/HP focus
Weapons: The Catch (Xiangling), Sacrificial Sword (Xingqiu), Stringless (Fischl), ER sword (Bennett)
Act 6: Emperor of Fire and Iron (Level 92)
Enemy Analysis
Boss generates Pyro shield on horns—requires Hydro to break. At 50% HP, shield regenerates. Without Hydro application, you can't deal meaningful damage.
Attack Patterns: Charging strikes, flame breath, ground pounds. Prioritize Hydro shielders for both shield-breaking and defense.
Premium Teams
Neuvillette: Neuvillette + Fischl + flex + flex Ayato Electro-Charged: Ayato + Fischl + Xingqiu + Bennett Tartaglia Vaporize: Tartaglia + Xiangling + Bennett + flex
Budget Clear
Team: Xingqiu, Fischl, Bennett, flex
Strategy: Deploy Xingqiu burst/skill for continuous Hydro application. Normal attack to trigger Rain Swords while Fischl's Oz provides Electro-Charged. Once shield breaks, activate Bennett burst and remaining damage abilities.
Alternative: Candace for strong single-hit Hydro application, but Xingqiu provides better consistency.
Energy Focus: Xingqiu needs 180-200% ER for both shield phases. Fischl maintains Oz uptime for continuous reactions.
Act 8: Knuckle Duckle (Level 95)
Enemy Analysis
Shield summons 5 Stamping Devices. Hit them with Electro-Charged reactions to fill gauges. Full gauge = shield break + stun state. Only Electro-Charged works—other reactions don't progress gauges.
Devices appear at fixed positions. AoE attacks hit multiple devices simultaneously. Electro-Charged Blessing's 70% Lunar-Charged boost accelerates shield-breaking significantly.
Premium Teams
Raiden + Kokomi: Raiden + Kokomi + flex + flex (wide AoE Electro-Charged) Yae Hypercarry: Yae + Xingqiu/Kokomi + Sucrose + Bennett (auto-targeting turrets) Fischl Carry: Fischl + Sucrose + Xingqiu + Bennett
Budget Clear
Team: Fischl, Xingqiu, Sucrose, Bennett
Rotation: Bennett burst → Xingqiu burst/skill → Fischl skill → Sucrose normal attacks to trigger reactions while grouping devices with skill
Key Mechanics:
Fischl's Oz + Xingqiu's Rain Swords = continuous Electro-Charged
Sucrose groups devices and shares EM to amplify reactions
Viridescent Venerer reduces Electro resistance
Investment Priority:
Sucrose: Stack EM on all artifacts for sharing
Fischl/Xingqiu: EM substats increase reaction damage
Bennett: Standard ER/HP build
Weapons: Sacrificial Fragments/Magic Guide (Sucrose), Stringless (Fischl), Sacrificial Sword (Xingqiu), ER sword (Bennett)
Act 10: Maguu Kenki (Level 100)
Enemy Analysis
Blocks long-range bow attacks. Requires melee or catalyst characters. Single-target DPS check—tightest time limit in the season.
Attack Patterns: Rapid slashes, teleportation strikes, delayed phantom attacks. Level 100 scaling creates one-shot potential. Shields or healing mandatory.
Premium Teams
Hu Tao Vaporize: Hu Tao + Xingqiu + Yelan + flex (highest single-target damage) Raiden Hypercarry: Raiden + Sara + Bennett + flex (concentrated burst damage) Yoimiya Vaporize: Yoimiya + Xingqiu + Fischl + Bennett (maintains close-medium range)
Budget Clear
Team: Xiangling, Xingqiu, Fischl, Bennett
Critical Requirements:
Xiangling: Level 80/90, 8/8/8 talents minimum, 4pc Emblem, 60/120 Crit, 180% ER
Xingqiu: Level 80/90, 8/8/8 talents, 4pc Emblem, 60/120 Crit, 180% ER
Fischl: Level 70/80, 6/6/6 talents, 2pc combos
Bennett: Level 70/80, burst talent 8 minimum
Rotation: Bennett burst → Xingqiu burst/skill → Fischl skill → Xiangling burst → maintain close range for Pyronado hits
Weapons (Non-Negotiable):
The Catch R5 (Xiangling)
Sacrificial Sword (Xingqiu)
Stringless (Fischl)
ER sword (Bennett)
Perfect execution required. Any rotation errors significantly impact clear times.
Arcana Challenges
Arcana I: Shadowy Husks
17 Level 100 Shadowy Husks (Standard Bearers, Line Breakers, Defenders). Spawn in groups of 3. Apply team-wide HP debuffs that stack per wave.
Strategy: AoE damage to clear waves before debuffs overwhelm. Electro-Charged teams excel through multi-target reaction spreading.
Team: Fischl + Xingqiu + Sucrose + Bennett
Sucrose groups enemies. Electro-Charged Blessing transforms reactions into primary damage. Shields become more valuable than healing as max HP decreases.
Arcana II: Super-Heavy Landrover
Level 100 boss with Fury gauge. Pyro damage fills gauge. At max Fury, boss gains Cryo shield immune to damage. Break shield before special skill executes.
Strategy: Controlled Pyro application. Reserve Hydro bursts for shield-breaking, not cooldown usage.
Team: Xiangling + Xingqiu + Fischl + Bennett
Xiangling fills Fury gauge. Xingqiu breaks Cryo shield. Fischl adds damage without triggering Fury. Balanced composition addresses all mechanics.

✅ Reserve top teams for Acts 8/10 ✅ Bring elemental counters for shields ✅ Match blessings to team composition ✅ Practice rotations in overworld first ✅ Invest resin in Xiangling/Xingqiu priority
