HSR 3.7 Memory of Chaos Guide | Analysis & Teams

Hey, Trailblazers! The Memory of Chaos: “Monkey Business” for Honkai: Star Rail Version 3.7 is officially live! This round’s environmental mechanics pack a serious punch — mastering them can make all the difference in clearing the toughest stages and earning those full-star rewards.

In this guide, we’ll break down enemy behaviors, stage mechanics, and the best team setups to help you breeze through every challenge and secure a perfect score with ease!

 

Buff Analysis

When an ally target attacks an Elite or Boss enemy with a corresponding Type weakness, add 1 Hits Per Action to "Memory Turbulence". Breaking an Elite or Boss enemy's weakness adds an additional 1 Hits Per Action, stacking up to 10 hits.
At the start of each Cycle, each hit of "Memory Turbulence" deals 1 instance of True DMG to a random enemy target.

 

Stage 12

First half

First half
WAVE 1	The Ascended
	Cyclonic Swarm Mother
WAVE 2	Stellaron Hunter: Sam

Wave 1: Key Mechanics
Boss: Cyclonic Swarm Mother (Weakness: Fire, Ice, Lightning)
Action Forward Mechanic: Similar to Lady of Crashing Waves, this enemy Actions Forward immediately after receiving 4 attacks (from Basic ATKs, Skills, Ultimates, or Memosprite attacks).
Note: If you trigger the 4th hit while it is currently the Boss's turn, the Action Forward effect is "eaten" (wasted) and will not trigger.
The "Incubation" Phase: On her second action, she adds [Incubation] to the Action Order. While [Incubation] is pending, she enters a defensive state taking 30% Reduced DMG.
Summoning & HP Drain Strategy: Every time you force the Boss to Action Forward before the [Incubation] turn occurs:
She summons 2 "Mirage Fizzle Kids" (these have 30% reduced DEF).
She loses 5% of her Max HP.
She delays the [Incubation] action by 10%. (Basically: Hit her often to make her hurt herself and delay her big move.)
The Wipe Mechanic: Once [Incubation] resolves, if there are still "Mirage Fizzle Kids" on the field, she will spam "Rain Is Born to Fall" (massive AoE DMG) continuously until all adds are dead.

Wave 2: Key Mechanics
Boss: Stellaron Hunter: Sam (Weakness: Lightning, Quantum, Imaginary)
Secondary Combustion (Phase Change): On Sam's second action, he consumes 3% Max HP to enter [Secondary Combustion].
Effect: Removes his Weakness Protection (unlocks Toughness bar), increases SPD by 50%, and all his attacks will drain 1% of his Max HP.
Molten Core (The SP Mechanic): During [Secondary Combustion], he "Combusts" your Skill Points (SP).
Penalty: When an ally uses a "Combusted" SP, they take fixed DMG (non-lethal) and their Incoming Healing is reduced by 90% (healing from their own kit or Light Cones is unaffected).
Breaking the State: Sam has a counter equivalent to 5 Molten Energy.
You need to hit Sam 5 times using offensive Skills that consume the "Combusted" SP.
Reward: Once the count hits 0, Sam exits [Secondary Combustion], regenerates all your Skill Points, and receives 50% Increased DMG until he recovers his stance.

Second half

Second half
WAVE 1	Noontide Gryphon
	Ichor Memosprite: Winged Serpent
WAVE 2	Borisin Warhead: Hoolay

Wave 1: Key Mechanics

Boss: Noontide Gryphon & Ichor Memosprite: Winged Serpent

The Noontide Gryphon revolves around its sweeping attack, applying [Aquila's Mark]. The first sweep is fixed to target the 3 allies on the Right, while the second switches to the Left. Defeating an enemy target allows you to dispel this mark (prioritizing the unit that dealt the killing blow). When a target possesses 2 stacks of [Aquila's Mark], all marks are consumed, dealing Fire DMG and causing Energy Loss.

PS: Therefore, you should place your Sustain/Support characters in Slots 3 & 4 (Right side). Keep units that rely on their Ultimate in Slots 1 & 2 to avoid the opening Energy drain.

The Winged Serpent enters a Charging state, gaining 5 [Whirl] stacks. Every time an ally attacks the Serpent, it removes 1 [Whirl] stack, triggers an AoE Counterattack, and inflicts [Corrosion] on your team. If it takes its turn while [Whirl] stacks still remain, it deals massive AoE DMG based on the remaining count.

PS: Healing or cleansing [Corrosion] grants a 50% DMG Bonus to the next attack. Teams with healers can utilize these counters to boost DPS.

Wave 2: Key Mechanics

Boss: Borisin Warhead: Hoolay

Hoolay's mechanics are relatively simple. Attacks from himself and his pack build up the gauge in the bottom right. Reaching 6/6 triggers [Moon Rage]. In this state, Hoolay gains +40% SPD, unlocks additional skills, and enhances the attacks of his wolves. This state only ends when Hoolay is Weakness Broken. During [Moon Rage], Hoolay possesses Irate stacks. Each time Hoolay attacks, he gains 2 stacks; every time you attack him, he loses 1 stack. Success: Reducing Irate to 0 deals 60 Toughness DMG to Hoolay immediately. Failure: Hoolay acts instantly and unleashes Lupine Chase Calls Bloody Gleam.

Lupine Chase Calls Bloody Gleam deals massive single-target damage and has a high chance to inflict [Terror Grip], which requires attacking Hoolay to dispel.

In Phase 2, the [Moon Rage] state adds a ground-smashing ability. This deals massive DMG to enemies while simultaneously inflicting 20% Action Delay (Pushback) on your team.
