Memory of Chaos HSR — Complete Endgame Mode Walkthrough

Memory of Chaos is Honkai: Star Rail's flagship endgame mode — and for Trailblazers serious about pushing their roster's ceiling, mastering the current cycle's 12 floors is where the real challenge lives. Refreshing on a bi-weekly cycle with rotating boss encounters and team modifiers, MoC rewards 800-1,200 Stellar Jade per refresh for full 36-star clears. This is the complete walkthrough for the current Memory of Chaos cycle — strategy, team building, and floor-by-floor breakdown.

🌌 What Is Memory of Chaos?

Memory of Chaos (MoC) is Honkai: Star Rail's premier combat-focused endgame mode, similar to Genshin Impact's Spiral Abyss. The mode features:

• 12 floors of escalating difficulty
• 2 halves per floor — Each floor requires clearing two separate enemy waves with different team compositions
• 3-star rating system — Stars awarded based on completion time
• Rotating bosses and modifiers — Bi-weekly refresh cycle
• Different character restrictions — Same character cannot appear in both halves of a single floor

The mode is the largest single source of Stellar Jade income in HSR's economy. For F2P Trailblazers, MoC clears are non-negotiable income — skipping floors costs approximately 1,600-2,400 Stellar Jade per refresh cycle (equivalent to 1-2 pulls).

⏰ Refresh Cycle and Reward Structure

Memory of Chaos refreshes on a bi-weekly cycle. Each refresh:

• Resets all floor configurations — New boss compositions and modifiers
• Resets reward eligibility — First-clear bonuses available again
• Updates time pressure standards — Star requirements adjust based on encounter design

Total potential rewards per cycle:

• Floor 1-5 clears: ~50-100 Stellar Jade per 3-star floor
• Floor 6-10 clears: ~100-150 Stellar Jade per 3-star floor
• Floor 11-12 clears: ~200-250 Stellar Jade per 3-star floor
• Full 36-star clear bonus: Additional rewards and prestige
• Total per cycle: 800-1,200 Stellar Jade depending on cycle difficulty

That's 1,600-2,400 Stellar Jade per month from MoC alone — equivalent to 1-2 limited pulls. For a complete F2P income breakdown, see our Stellar Jade Saving Guide.

🎯 Floor Mechanics

Each Memory of Chaos floor presents:

• Two halves — Sequential enemy waves requiring separate teams
• Cycle limit — Total cycles allowed across both halves (typically 10-12 cycles total)
• Star requirements — 3 stars = clear within remaining cycle budget; 2 stars = slower completion; 1 star = clear at all
• Environmental modifiers — Element-specific damage amplifications, action advance bonuses, weakness break enhancements
• Boss encounters — Pinnacle floors (11-12) feature signature boss encounters with phase mechanics

The restriction matters significantly: you need at least 8 well-built characters to consistently 3-star Memory of Chaos. Single-team focus accounts struggle past floor 8.

👥 Team Building for Current Memory of Chaos

The optimal MoC teams for Version 4.3 leverage the strongest current meta compositions. With Phase 2 reruns approaching June 24, these teams become even more powerful:

Phainon Hyper-Carry (Phase 2 Ready):

• Phainon (Physical DPS — top single-target damage)
• Cerydra (Coup de Main duplication)
• Sunday (Action advance + ATK buff)
• Huohuo or Aventurine (Sustain)

Castorice Hyper-Carry (S+ Tier with Cyrene):

• Castorice (Quantum DPS)
• Cyrene (Memosprite + Recollection support)
• Remembrance Trailblazer (Memospite synergy)
• Sustain

Acheron Nihility Team:

• Acheron (Lightning DPS — Ultimate-focused)
• Pela (DEF shred + Nihility stack)
• Silver Wolf (Weakness implant + Nihility stack)
• Aventurine or Gallagher (Sustain)

Firefly Break Team:

• Firefly (Fire DPS — Break-focused)
• Ruan Mei (Universal break amplifier)
• Harmony Trailblazer (Break support)
• Gallagher or Lingsha (Sustain + Fire weakness implant)

The Herta Erudition Team:

• The Herta (Ice Erudition AoE DPS)
• Tribbie or Sparkle (Critical buff)
• Robin or Sunday (Team DMG buff)
• Sustain

Mix these compositions across the two halves of each floor based on enemy element weaknesses. Trailblazers running only one team archetype hit walls past floor 9.

🛡️ Floor-by-Floor Strategy

Floor configurations rotate bi-weekly, but strategic patterns remain consistent:

Floors 1-3 (Entry):

• Single boss or small group encounters
• Focus on rotation practice — habits formed here carry through harder floors
• Most teams clear comfortably with minimal investment
• Test new team compositions safely

Floors 4-6 (Mid-tier):

• Multi-enemy compositions appear; group control matters
• AoE-capable DPS (The Herta, Argenti, Himeko) shine here
• Sustain stress increases — undergeared healers struggle
• Environmental modifiers begin meaningful impact

Floors 7-9 (Difficulty Spike):

• Single-boss encounters with mechanic complexity
• Specific element weaknesses critical for cycle efficiency
• Sustain teams must handle higher incoming damage
• Standard for 2-star clears, 3-star requires optimization

Floors 10-12 (Pinnacle):

• Signature boss encounters with phase mechanics
• Highest difficulty in current MoC
• Sustained DPS focus over multiple phases
• Time pressure intense — every cycle matters
• 3-star clear requires near-perfect execution

3-Star Clear Requirements:

• Complete within typically 3-5 cycles (depending on floor)
• Avoid wipe states (no character deaths affect star rating)
• Specific star conditions vary; read floor modifiers carefully

📊 Common Mistakes That Cost Stars

• Wrong element matching — Throwing Quantum damage at Quantum-resistant bosses wastes precious cycles
• Single-team focus — Trying to use the same composition for both halves caps your performance ceiling
• Underleveled traces — MoC assumes Trace levels at 8+ and Relics at +12 minimum
• Skipping environmental modifiers — Some modifiers triple damage of specific damage types; ignoring them wastes potential stars
• Poor SPD tuning — Cycle count depends heavily on character SPD; SPD-tuning teams matters more here than other modes
• Forgetting Trace effects — Some characters have Trace-level bonuses that activate only at higher difficulty thresholds
• Sustaining beyond necessity — Over-investing in sustain leaves DPS underbuilt; balance matters

💎 Energy Management Across Halves

One of MoC's underappreciated mechanics: Energy carries over between halves of a floor. This affects team building strategy:

• Characters who finish half 1 with high Energy can immediately fire Ultimate at start of half 2 (if reused)
• Plan rotations to leave Burst-dependent supports near full Energy for next half's opening
• Don't waste high-Energy characters on lower-priority targets in half 1

This is one of the highest-impact optimization habits for consistent MoC clears.

🎯 Reward Optimization Tips

Per MoC refresh cycle, maximize Stellar Jade by:

• Star ratings matter — Each star contributes to final rewards independently
• Don't skip lower floors — Floor 1-5 clears are easy and add cumulative rewards
• Time investment pays — Spending 30-60 minutes per refresh pushing 3-stars is high return per minute
• Practice teams in lower floors first — Test team compositions on floors 4-6 before attempting 10-12

💡 Pro Tips for Pushing MoC

• Practice in Simulated Universe first — Lower stakes, similar combat patterns
• Pre-build Energy — Charge ultimates on weaker enemies in early waves, save them for boss windows
• Use SPD tuning religiously — Faster characters get more turns; SPD calculators (Prydwen, HSR-Optimizer) accelerate optimization
• Watch top community clears — YouTube channels like StarRailStation, HSR Hub post clears with timestamps; copy proven strategies
• Don't punish yourself for 2-star clears — Some MoC floors are designed so 2-stars are reasonable but 3-stars require near-perfect execution
• Reset attempts liberally — Failed run costs no resources beyond your time. Restart immediately if the first cycle isn't going well
• Update teams every refresh — Floor mechanics change; recycling old teams loses stars
• Track team composition history — Note which teams cleared which floors; pattern recognition accelerates future clears

🔄 What Changes Between Refreshes

When MoC rotates floor configurations, expect:

• Different boss encounters per floor — Rotation pool of ~15-20 boss types
• Updated environmental modifiers — Different elemental amplifications, action advance bonuses
• Adjusted star requirements — Some refreshes are easier than others based on enemy/modifier combinations
• New character recommendations — Based on current meta and Phase 2 banners

Adapt accordingly — what cleared last refresh may not work this refresh. Reading floor modifiers carefully on each refresh is the single highest-impact habit for consistent MoC clears.

🎯 Should You Push Memory of Chaos?

Push MoC if:

• You have at least 8 properly built characters across multiple elements
• You enjoy mechanical optimization and rotation challenges
• You want maximum Stellar Jade income (F2P or not)
• You have time to adapt team compositions every 2 weeks

Stick to Pure Fiction or Apocalyptic Shadow if:

• Your roster is still building (less than 8 properly built characters)
• MoC's time pressure stresses you out
• You play casually without engaging with rotation optimization
• You're early in your account journey

Pure Fiction and Apocalyptic Shadow rewards are still substantial — don't feel pressured into MoC before your roster supports it.
