Honkai: Star Rail Memory of Chaos EX Carry Clears and Builds

To maximize clear speed in Honkai: Star Rail high-tier Memory of Chaos stages using hyper-invested EX Eidolon damage dealers, players must tailor team compositions and combat pacing to each character's specific resource mechanic. Acheron relies on rapid allied debuff application, Jing Yuan requires precise action timing to stack Lightning-Lord attacks, and Dan Heng Imbibitor Lunae demands strict team-wide Skill Point management.

Carry Node Matchups and Mechanical Profiles

Assign carries based on enemy layout, elemental weaknesses, and support requirements. The 4.7 Chaos showcase demonstrates distinct operational roles for each damage dealer:

Character	Showcase Node	Key Mechanical Focus	Showcase Timestamp	Primary Operational Risk
Acheron	First Half	Debuff accumulation and Slashed Dream Ultimate	00:00	Support lock-in; burst delays if debuffs fail
Jing Yuan	Second Half	Lightning-Lord stack building and action advance	03:03	Crowd control cancels summon damage
Dan Heng Imbibitor Lunae	First Half	3-tier Enhanced Basic Attack SP consumption	06:08	Skill Point starvation forces low-tier attacks

Acheron (First Half): Thrives against multi-elite waves. Her Ultimate dynamically splits slashes across all targets on the field, preventing wasted over-kill damage on single minions.
Jing Yuan (Second Half): Serves as a consistent anchor against lightning-vulnerable encounters. The Lightning-Lord deals steady area damage while personal skills sweep minor targets.
Dan Heng Imbibitor Lunae (First Half): Excels at shredding high-durability central elites with imaginary splash damage when toughness bars require rapid reduction.

Acheron: Debuff Stacking and Ultimate Cycling

Acheron bypasses standard energy generation entirely, charging her Ultimate through Slashed Dream stacks. Every ally action that applies a debuff adds a stack, making the support rotation the sole driver of clear speed.

Prioritize Nihility allies: Run teammates capable of applying debuffs on basic attacks or skills to guarantee a charge contribution every turn.
Focus primary targets: Apply single-target debuffs to the central elite enemy to concentrate Crimson Knot accumulation while blast abilities handle surrounding minions.
Manage team constraints: Because Acheron requires consistent debuffers, standard Harmony supports cannot slot into the team unless specialized light cones or high-investment eidolons provide reliable debuff utility.

Jing Yuan: Lightning-Lord Stack Tuning and Cleansing

Jing Yuan's damage relies on building the Lightning-Lord to 8–10 stacks before each activation, which raises the summon's speed and total strike count.

Maintain skill rotations: Use Jing Yuan's Skill on every turn and time his Ultimate to ensure the Lightning-Lord reaches full strike capacity before acting.
Prevent crowd control interrupts: If Jing Yuan is frozen, imprisoned, or heavily speed-debuffed, the Lightning-Lord forfeits its turn. Pair him with dedicated cleansers or effect resistance buffers tuned to act immediately before Jing Yuan in the action order.
Sustain debuffs on boss targets: While the Lightning-Lord's bounces sweep adjacent enemies, single-target bosses require active defense shred to absorb the full multiplier.

Dan Heng Imbibitor Lunae: Skill Point Discipline

Dan Heng Imbibitor Lunae deals maximum imaginary burst by expending three Skill Points per turn to cast Fulgurant Leap. Sacrificing enhancement levels drastically lowers damage output.

Enforce positive SP generation: Teammates must rely on Basic Attacks and avoid casting their own Skills unless critical to survival.
Cycle Ultimates for Squama Sacrosancta: Use Imbibitor Lunae’s Ultimate during damage windows to acquire Squama Sacrosancta, which substitute directly for future Skill Point costs.
Avoid intermediate attacks: Never attack with single- or double-tier enhancements; wait for three available Skill Points to fully stack his internal Critical Damage and damage amplification buffs.

Gearing Baselines and Relic Priorities

Replicating high-end clear times requires hitting specific stat floors showcased at the 11:37 mark:

Acheron: Reach a minimum 70% to 80% Critical Rate before stacking Critical Damage. Use an Attack rope alongside a Lightning Damage or Attack planar sphere.
Jing Yuan: Aim for at least 75% Critical Rate and 150% Critical Damage to ensure all 10 Lightning-Lord strikes land critically. Equip Speed boots unless running an aggressive action-advance support setup that guarantees two Skill casts per cycle.
Dan Heng Imbibitor Lunae: Secure a 70% Critical Rate baseline to fulfill planar set passive requirements, paired with Imaginary Damage and high Critical Damage. Choose between an Energy Regeneration Rate rope or an Attack rope based on whether your support line sustains a full three-point rotation.
