HSR Memory of Chaos Guide: Best Teams & Strategies (May 2026)

Earning 36 stars in the endgame requires a perfect blend of speed tuning and exploitation of the current Memory Turbulence. This guide breaks down the optimal setups for the May 2026 “Grand Finale” cycle.

📝 Editorial Note: This guide is AI-assisted and game data evolves rapidly. Please cross-reference with in-game information. Updated: 2026-05-13.

Overview

The Memory of Chaos (MoC) remains the ultimate test for any Trailblazer’s roster. As of May 2026, the mode continues its six-week rotation within the “Treasures Lightward” system, alternating with Pure Fiction and Apocalyptic Shadow. The current cycle, titled “Grand Finale,” is heavily tailored toward the high-frequency combat style introduced in Version 4.1, specifically benefiting characters who can act multiple times within a single turn or trigger frequent follow-up attacks (FUA).

To secure a full 36-star clear, you must complete Stage 12 within 10 total cycles (remaining cycles ≥ 20) while ensuring all four team members survive both halves. The aggressive AI scaling in the latest patches means that traditional “glass cannon” builds are increasingly risky; survivability via high-HP supports or high-frequency shielders is now a requirement rather than a luxury.

Understanding the ‘Grand Finale’ Turbulence

The “Grand Finale” mechanic revolves around “Punchline” points. Every time an ally performs an attack—including Basic ATKs, Skills, Ultimates, and Follow-up Attacks—they accumulate 1 Punchline point. In Stage 12, these points can stack up to a maximum of 50. At the start of every new cycle, the Memory Turbulence triggers, dealing massive True DMG to all enemies based on the total number of accumulated points.

Because the damage scales exponentially with the number of stacks, teams that can reach the 50-stack cap early in the cycle will see the most significant benefit. This makes characters like Ashveil, who can trigger multiple follow-up attacks per action, the undisputed kings of this rotation.

Stage 12 Boss Analysis: Zandar and Pollux

Stage 12 features a daunting lineup of bosses that require specific elemental coverage and mechanical knowledge.

Node	Boss	Recommended Elements	Key Weaknesses
Node 1	First Genius, Entelechy, Zandar	Lightning, Ice, Quantum	High Toughness, Summon-heavy
Node 2	Pollux, The Sunken Star	Physical, Imaginary, Wind	High DMG Burst, CC Vulnerable

Zandar (Node 1): Zandar operates in two distinct modes: Evolution and Disputation. In Evolution Mode, he summons Titankins that buff his speed and damage. In Disputation Mode, he shifts focus to “Black Tide” summons. The key to defeating Zandar is triggering his “Antinomy” state by breaking his summons’ Toughness, which applies a permanent 50% Vulnerability debuff to Zandar himself.

Pollux (Node 2): Pollux is a massive single-target threat that utilizes “Starfall” mechanics to target the ally with the highest current HP. While he deals devastating damage, he is highly susceptible to Weakness Break. Characters like Mydei or the Remembrance Trailblazer are essential here to keep Pollux locked down and prevent him from reaching his “Nova” state.

Best Weapons

The weapon meta for MoC 12 in May 2026 emphasizes two things: Energy Regeneration Rate (ERR) and base survivability. With enemies now capable of one-shotting units under 3,500 HP, Light Cones with high base HP and DEF stats have moved up the tier list.

Top 5 Light Cones for MoC 12

Name	Path	Key Benefit	Best User
The Finale of a Lie	The Hunt	30% Crit Rate; 24% DEF Shred after 4 FUAs	Ashveil
Long Road Leads Home	Destruction	24% Max HP; DMG boost based on HP lost	Mydei
Long May Rainbows Adorn the Sky	Remembrance	Increases DMG taken by enemies by 18%	Hyacine / Castorice
Geniuses’ Repose (S5)	Erudition	48% Crit DMG after defeating an enemy	Jade / The Herta
Post-Op Conversation (S5)	Abundance	16% ERR; 30% Outgoing Healing on Ultimate	Hyacine / Lynx

Signature vs. F2P Light Cone Performance

Ashveil’s signature Light Cone, “The Finale of a Lie,” is currently the gold standard for Elation-path and high-frequency Hunt characters. The DEF shred it provides is independent of other debuffs, allowing it to stack with Ashveil’s innate kit for a total of [information unavailable]% DEF reduction on the “Bait” target.

For F2P players, the gap is widening but remains bridgeable. “Geniuses’ Repose” at Superimposition 5 remains incredibly strong for wave-clearing in Node 1. However, for Node 2, Destruction units without “Long Road Leads Home” may struggle with the sheer HP requirements to survive Pollux’s “Starfall” attack. In these cases, switching to a more defensive Light Cone like “A Secret Vow” is recommended.

Energy Regeneration Breakpoints for 0-Cycle Clears

To achieve a 0-cycle clear in the current meta, your Harmony supports (Sunday, Robin, or Tribbie) must be able to use their Ultimates by the start of the second action in the first cycle. This typically requires an ERR Rope and at least one instance of external energy generation, such as the “Quid Pro Quo” Abundance Light Cone or the Remembrance Trailblazer’s energy-sharing traces.

Best Disks (Artifacts)

In May 2026, Speed (SPD) tuning is no longer optional for MoC 12. The “Grand Finale” Turbulence demands that your team acts as many times as possible before the cycle resets to maximize Punchline stacks.

Recommended Relic Sets for MoC 12

Set Name	2pc / 4pc Bonus	Recommended Characters
Ashblazing Grand Duke	FUA DMG increase; ATK% stacks	Ashveil, Topaz, Jade
Iron Cavalry Against Scourge	Break Effect; DEF Ignore on Break	Castorice, Firefly, Boothill
Messenger Traversing Hackerspace	SPD increase; Team SPD buff on Ult	Sunday, Robin, Tribbie
Scholar Lost in Erudition	Skill DMG; Crit Rate boost	Mydei, Remembrance Trailblazer

Essential Substat Priorities for Stage 12 Survival

While offensive stats are priority, the following survival thresholds are mandatory for Stage 12:

Main DPS: 3,800+ HP / 1,000+ DEF
Supports: 4,500+ HP / 1,200+ DEF
SPD Breakpoints: 134 is the minimum, but 160 is preferred for Tribbie and Sunday to ensure three actions in the first two cycles.

Optimal Planar Ornaments for Version 4.1

The “Forge of the Kalpagni Lantern” remains the premier choice for Break-focused units like Castorice, providing much-needed SPD and Break Effect. For follow-up teams, the “Duran, Dynasty of Running Wolves” set is superior, as it provides a permanent Crit DMG buff that persists across waves—crucial for the multi-phase Zandar fight.

Team Comp

The Version 4.1 meta is dominated by two archetypes: The Ashveil Follow-Up Core and the Remembrance Break Meta.

Best Teams for MoC 12

Team Type	Team Composition	Best Node
Ashveil FUA Core	Ashveil, Sunday, Tribbie, Aventurine	Node 1 (Zandar)
Mydei Hypercarry	Mydei, Robin, Cyrene, Hyacine	Node 2 (Pollux)
Castorice Quantum Break	Castorice, Remembrance TB, Ruan Mei, Gallagher	Node 1 (Zandar)
Budget F2P	Dan Heng • Permansor Terrae, Asta, Yukong, Lynx	Node 2 (Pollux)

The Ashveil FUA Core

This team is designed to break the “Grand Finale” Turbulence. Ashveil marks an enemy as “Bait,” and every time Sunday or Tribbie attacks that target, Ashveil launches a follow-up. Tribbie’s “Numinosity” state adds additional Quantum damage to every hit, which helps shred Zandar’s Toughness bar. Sunday acts as the primary battery and action-advancer, ensuring Ashveil never runs out of “Gluttony” stacks.

Break Meta: Remembrance Trailblazer Synergy

The Remembrance Trailblazer (Ice/Remembrance) has become a staple for Node 2. Their ability to summon “Mem” adds a fifth actor to the turn order, which significantly boosts the Punchline stack count. When paired with Castorice, the team can effectively “freeze” Pollux’s action bar through repeated Weakness Breaks and the “Dissociation” status effect.

Budget Teams for 30-Star Clears

If you lack the latest 5-star units, a well-invested Dan Heng • Permansor Terrae team can still clear MoC 11 and 12. Focus on maximizing Asta’s SPD buff to ensure your team takes enough turns to trigger the Turbulence damage. While you may not hit the 50-stack cap, reaching 25–30 stacks is usually enough to clear the waves if your manual targeting is precise.

Rotation

The difference between a 4-cycle clear and a 10-cycle fail often comes down to how you manage your Ultimates and Skill Points (SP).

Maximizing the ‘Punchline’ True Damage

To maximize the “Grand Finale” effect, do not use all your Ultimates at once. Since every attack counts as a stack, you should space out your Ultimates to ensure you are always building toward the 50-stack cap. If you reach 50 stacks early in a cycle, save any remaining offensive Ultimates for the start of the next cycle to get a head start on the new stack count.

Handling Zandar’s Form Shifts

When Zandar enters Evolution Mode, he will summon two Titankins. Do not ignore them. Killing a Titankin grants your team the “Antinomy” buff, which restores [information unavailable] Energy and increases DMG dealt by 30%. In Disputation Mode, Zandar becomes much more aggressive. Save your sustain’s Ultimate (Aventurine or Hyacine) specifically for his “Query: Prime Mover’s Outcome” attack, which deals distributed damage across the entire party.

0-Cycle Opening Rotation for Ashveil Teams

Technique: Use Ashveil’s technique to enter battle with 3 Gluttony charges.
Ashveil Turn: Use Skill on the elite/boss to apply “Bait.”
Sunday Turn: Use Skill on Ashveil to advance his action.
Ashveil Turn: Use Basic ATK (recovers 1 SP due to “Bait” mechanic).
Tribbie Turn: Activate Ultimate to create the “Zone” and trigger Ashveil’s FUA.
Sunday/Robin: Activate Ultimate after the DPS has finished their turn to provide a full team action advance.

FAQ

Unlocking and Reset Schedule

How do I unlock Memory of Chaos? You must clear Stage 15 of the “Last Vestiges of the Towering Citadel” (the permanent Forgotten Hall) to gain access to the MoC floors.

When does MoC reset? MoC resets every 6 weeks on a Monday at 04:00 server time. It alternates with Pure Fiction and Apocalyptic Shadow, meaning there is always an endgame mode refreshing every two weeks.

Stellar Jade and Shop Rewards

Clearing all 12 stages with 36 stars rewards a total of 800 Stellar Jades. Additionally, you earn “Jade Feathers,” which can be traded in the Priceless Jewels shop for Light Cone Manifests, Self-Modeling Resin, and Star Rail Passes.

Milestone	Rewards
3 Stars (per stage)	60 Stellar Jades + 20,000 Credits
Full 36-Star Clear	800 Stellar Jades + 600 Jade Feathers

Troubleshooting Low Damage Output

If you are failing to clear within the cycle limit, check your SPD tuning. Most players fail because their supports are too slow to generate the Turbulence stacks. Ensure your Harmony units are at 143+ SPD. If survivability is the issue, swap your ATK% sphere for an HP% sphere on your supports; a dead support provides zero buffs.
