HSR 2.0 MoC tier list puts SS-tier Acheron and Firefly at the top for those flawless 36-star clears. We're talking Stage 12 with Furiae Praetor at 2,011,149 HP and Flame Reaver pushing 3,631,241 HP. Key mechanics? 40% Turbulence boosts, 75% Break Efficiency, and teams nailing it in 5.5 cycles. Fresh update: Dec 8, 2025.

Diving into HSR 2.0 Memory of Chaos Tier List

What's Memory of Chaos All About?

Picture this: enemies tanking over 2M HP right out the gate. Stage 12 first half? Furiae Praetor with 2,011,149 HP, Flame Reaver at 3,631,241 HP. Turbulence kicks in 40% damage amps through memosprites—plus 2 True Damage hits per cycle. Second half demands AoE nukes hitting Physical/Fire/Imaginary weak spots; keep eyes peeled for Dreamjolt Gorilla and Ichor Memosprite.

Quick playbook: Scout weaknesses before dropping a cycle. Stack that 40% Turbulence. And sustain through 2M+ HP pools for full 36-stars.

How We Built This Tier List (And When)

We rank on raw DPS, tankiness, and utility tuned for 36-star perfection—SS tier demands 300k+ Super Break output. Pulled from 5.5-cycle clears, post-2.0 meta as of Dec 8, 2025, 1:30 PM. Standouts? SS damagers like Acheron and Firefly. SS sustains: Huohuo, Fu Xuan.

S+ Tier: The Absolute Gods of MoC

Why Firefly Dominates

SS Firefly? She's dropping 300k+ Super Break on shattered foes, clearing in 5.5 cycles flat.

Premium squad: Firefly + Harmony Trailblazer + Ruan Mei (75% Break Eff) + Lingsha. Trailblazer cracks 'em open. Ruan Mei juices the breaks. Firefly unloads massive bursts. Lingsha mends the backlash.

F2P route: Firefly + Imaginary Trailblazer + Asta (SPD tuning) + Natasha. Still 36-stars, no sweat.

Acheron's Hypercarry Mayhem

SS Acheron shines as hypercarry, pulling 60% damage amps from two Nihility buddies; Silver Wolf shreds 45% DEF.

Premium: Acheron + Silver Wolf + Sparkle (CRIT DMG stacks) + Huohuo (energy funnel). Rotation: Silver Wolf's 45% DEF down. Sparkle action-forwards. Acheron stacks Salsotto. Huohuo loops Ult.

F2P: Acheron + Pela (40% AoE DEF shred) + Tingyun (ATK buffs) + Gallagher (Besotted debuffs). E2 flex: Acheron + Jiaoqiu (Vuln) + Sunday (advance) + Aventurine (shields/Ult debuff).

S Tier: Elite Crew That Delivers

Prime S-Tier Damage Dealers

S damagers like Black Swan, Seele, Boothill, Jingliu, Yunli, Rappa, Kafka, Dan Heng IL, Mydei, Anaxa, Archer handle ST or AoE duties. Black Swan and Seele pump high DoT/ST but miss Acheron's reliability. Yunli/Jingliu? Physical beasts, situational against Firefly's Break dominance.

Run it like: Pair with Robin/Ruan Mei for DPS spikes. Layer 40% DEF shred. Cycle Ults every 5 turns.

Top Supports and Tanks

S supports: Robin, Ruan Mei (75% Break Eff), Cerydra, Cyrene (pure buffers/debuffers). S tanks: Luocha, Gallagher (Besotted), Lingsha (Break healing). Slap SPD boots on supports; energy regen relics keep 'em spinning.

A Tier: Solid Picks with Caveats

Phainon and Evernight Steal the Show

A-tier Phainon grants +1 Coreflame per ally action, +2 on Skill; hit 12+ stacks for 8 extra turns at 60% SPD, 25% HP resist.

Premium: Phainon + Sunday (2 Ult stacks) + Bronya (advance) + Ruan Mei (RES PEN). Stack via actions. Trigger Enhanced mode. Burst without sustain crutches.

Evernight's Ult? 200% Max HP AoE Ice, 30% Vuln/60% DMG boost. Skill summons 10% HP Evey, shreds 60% CRIT on memosprites. Premium: Castorice + Evernight + Cyrene + Hyacine.

Rest of A-Tier

Moze, March 7th, Jade (ST focus), Blade, Qingque, Xueyi, Guinaifen—all crave god-roll relics/LC and weakness exploits.

B Tier and Below: Niche or Skip

The Bottom Feeders

B damagers—Sampo, Misha, Himeko, Herta, Welt, Luka—niche as hell, investment sinks. C-tier like Yanqing, Serval? Beginner fodder only. A supports stay F2P kings: Bronya, Tingyun, Pela, Imaginary Trailblazer. B options (Asta, Hanya, Yukong) get outshined.

When to use? Early cycles or F2P ramps. High-end? Swap for Huohuo (SS). Big trap: Dumping relics without Eidolons tanks viability.

Killer Team Comps from Top Tiers

Hypercarry Setups
