Honkai: Star Rail Memory of Chaos 3.5 - Pillar of Genesis Guide

Memory of Chaos represents as one of Honkai: Star Rail's endgame challenges, testing players' mastery of boss mechanics and team building. Unlike Pure Fiction's wave-clearing focus or Apocalyptic Shadow's specific mechanics, Memory of Chaos mostly emphasizes sustained blast damage, precise element exploitation, and resource management. The mode requires clearing twelve progressively difficult stages using two separate teams, with each team facing unique boss encounters that demand specific elemental coverage and mechanical understanding. And for Trailblazers who want to clear Honkai: Star Rail Version 3.5's Memory of Chaos, do not forget to follow our guide below!

Understanding the Core Mechanics

Memory of Chaos operates on a biweekly refresh cycle, offering Stellar Jades and other progression items as rewards for full completion. Players must clear the stages within strict time constraints, typically requiring completion within 10 cycles of the 30-cycle maximum to earn full rewards. The defining feature that separates each Memory of Chaos cycle is the Memory Turbulence buff, which changes every rotation and fundamentally shapes the meta compositions.

The current Pillar of Genesis cycle introduces a powerful Skill-focused mechanic. After an ally character uses a Skill to attack or a memosprite attacks, the system adds one hit to Memory Turbulence, stacking up to 10 times. At the start of every cycle, each accumulated hit deals True Damage to a random enemy target. This mechanic heavily favors Skill-based damage dealers and characters from the Path of Remembrance, whose memosprites contribute additional hits to accelerate the damage accumulation.

Element Matching and Weakness Exploitation

Success in Memory of Chaos hinges on bringing the correct elemental types to exploit enemy weaknesses. Weakness Break mechanics deal substantial toughness damage and trigger powerful delayed actions on elite enemies, making element matching non-negotiable for competitive clear times. Stage 11 and 12 present distinct elemental requirements that demand diverse roster investment.

Stage 11's first half features Hoolay, the Borisin Warhead, who is weak to Physical and Fire damage. Hoolay's Moon Rage mechanic makes him particularly dangerous when entering this state, he summons Lupine Chase and becomes significantly more aggressive. Players must focus on breaking his toughness during Moon Rage to prevent devastating follow-up attacks. The second half introduces Lance of Fury, vulnerable to Quantum and Ice damage, alongside supporting enemies that require area-of-effect capabilities despite the single-target focus.

Stage 12 escalates the challenge with Lady of Crashing Waves and Gepard in the first half, both weak to Physical and Lightning. Lady of Crashing Waves continuously summons Servant of Tides minions that must be eliminated. These summons deals significant damage to adjacent enemies when defeated, creating strategic decision points about target priority. The second half features Theoros: Lygus, weak to Ice and Wind, demanding completely different team compositions from the first half.

Dominant Meta Compositions

The current Pillar of Genesis cycle strongly favors Skill-based damage dealers due to the Memory Turbulence mechanic.

Remembrance Path characters like Castorice and Evernight excel in this cycle, as their memosprites contribute directly to Memory Turbulence stacks though current buffs don't specifically boost memosprites. Hyacine pairs naturally with Castorice and Evernight, offering support capabilities that enhance memosprite performance and overall team damage.

Physical damage dealers like Phainon, Boothill, Clara, and Yunli benefit from Stage 11 and 12's Physical weakness requirements. Phainon's Skill-based attacks and Ultimate recharge from Theoros: Lygus makes him a perfect match-up for the second half. Boothill's enhanced basic attacks and break-focused kit align perfectly with boss encounter demands, while Clara's and Yunli's counter-attack mechanic generates consistent damage against aggressive bosses like Hoolay.

For Lightning requirements, Jing Yuan and Kafka offer distinct approaches. Jing Yuan's Lightning Lord provides sustained follow-up damage ideal for extended boss fights, while Kafka excels when enemies feature multiple adds due to her DoT spread mechanics.

Building these premium teams often requires significant resource investment, which LootBar facilitates through convenient and affordable top-up options.

Strategic Considerations

Effective Memory of Chaos progression requires more than strong characters. Players must master action economy and Skill Point management. The Skill and memosprite attacks Memory Turbulence creates consideration between maximizing buff stacks and maintaining sustainable Skill Point generation.

Understanding boss attack patterns allows strategic timing of defensive abilities. Hoolay's Moon Rage phase becomes predictable after initial exposure, letting players save burst windows for maximum vulnerability periods. Lady of Crashing Waves' summon patterns create clear priorities that eliminating Servant of Tides quickly prevents overwhelming pressure while dealing adjacent damage to the primary target. Consider that Lygus' Ultimate recharge has a downside of reducing 50% Max HP when the Ultimate is used and number of enemies spawned and memosprites that disappear will increase his counter below his HP bar that forces him to switch mode after reaching 10. When Lygus switches form, he will gain 50% Vulnerability that is stackable until the battle ends.

Conclusion

Memory of Chaos stands as Honkai Star Rail's premier test of roster depth, mechanical understanding, and strategic team building. Success demands mastery of elemental coverage, Skill Point economy, and boss-specific mechanics rather than raw damage output alone. The current Pillar of Genesis cycle rewards Skill-based compositions and Remembrance Path characters, but flexible team building and precise execution remain paramount.

While premium characters like Phainon, Castorice, and Evernight dominate the current meta, careful planning and mechanical execution enable budget-conscious players to achieve competitive clear times using four-star alternatives. For those seeking to expand their roster with limited characters and signature Light Cones, top up Honkai Star Rail through LootBar to maximize your competitive advantage and enjoy the full depth of Memory of Chaos challenges.
