As Trailblazers venture into Amphoreus during Honkai Star Rail’s ongoing narrative, they’ll collaborate with the Chrysos Heirs on the Flame-Chasenb expedition to confront powerful Titans and secure their coreflames. The version 3.2 update guides players toward Styxia, the legendary Dragonborn City, where they’ll pursue the Death Titan Thanatos and encounter formidable adversaries like Pollux.

Pollux, designated as Netherwing Husk and Ferry of Souls, represents a primary boss encounter with specific elemental vulnerabilities to Wind, Quantum, and Imaginary damage types. This formidable foe summons additional enemies known as Long Arms of Sorrow, which share a collective health pool with Pollux’s main dragon form. These summons typically exhibit three random weaknesses selected from Lightning, Wind, Quantum, and Imaginary elements, requiring adaptive team strategies.

The combat mechanics feature standard boss attack patterns including single-target assaults and area-of-effect abilities. However, the encounter’s distinctive challenge stems from Atrophy DMG, a specialized damage category that completely ignores defensive shields and directly depletes character HP pools. This mechanic renders Preservation path characters largely ineffective against Pollux, as their shielding capabilities provide no protection against this unique damage type.

Key Battle Mechanics and Status Effects

After executing several combat turns, Pollux activates the devastating To Die in Aromatic Pain technique, transitioning into the Fragrance of Death state. This transformation triggers massive area damage that reduces your entire team’s HP to 1 point while applying the debilitating Indulging Slumber status effect to all characters.

Following this non-lethal assault, your party members receive immediate turn priority. To recover from this critical state, employ healing specialists or offensive actions against Pollux to diminish the Desperate Bubble meter. Unfortunately, reducing this charge provides minimal health restoration, and dependence on the Desperate Bubble for healing characters affected by Indulging Slumber substantially reduces the damage Pollux receives from your attacks.

The encounter design mandates including at least one healing specialist in your team composition. By restoring teammates’ health above approximately 50% maximum HP, you can eliminate the Indulging Slumber status condition and resume dealing complete damage to Pollux. Failure to remove this effect results in Pollux dealing significantly amplified damage to afflicted characters, often leading to instant defeat.

Strategic Insight: The Fragrance of Death state occurs on a predictable turn cycle, allowing prepared teams to position healing abilities accordingly. Advanced players should track turn order to pre-cast healing ultimates just before this mechanic triggers.

Optimal Team Composition Strategies

Preservation characters, including meta staples like Aventurine, have traditionally ranked among Honkai Star Rail’s most reliable sustain options. However, Pollux’s shield-penetrating attacks make defensive specialists counterproductive for this specific encounter. Deploying dedicated healers becomes non-negotiable, with Gallagher, Lingsha, and Luocha emerging as premier sustain choices against Pollux’s mechanics.

When Pollux inflicts your squad with Indulging Slumber after several turns, affected characters suffer dramatic damage reduction. The exclusive method for removing this impairment involves healing characters beyond the 50% health threshold. During debuff periods, prioritize therapeutic actions over offensive maneuvers. With single-target healers like Luocha or Gallagher, focus restoration on your primary damage dealers to maintain offensive pressure while managing the status effect.

Neglecting to clear the Indulging Slumber condition or failing to break the boss’s Weakness Bar prompts Pollux to execute an overwhelming nuke attack capable of eliminating your entire team. The health-draining mechanics make this encounter particularly favorable for HP-fluctuation specialists like Castorice, Blade, and Mydei. Castorice stands out as the optimal selection, leveraging health variations to recharge her Ultimate ability and summon Netherwing companions.

When Pollux employs To Die in Aromatic Pain against teams featuring Castorice and reduces their health to 1, she exceptionally efficiently charges her Ultimate capacity. Similarly, Mydei and Blade accumulate valuable stacks from Pollux’s HP-draining assaults. Conveniently, Pollux maintains vulnerability to the elemental types wielded by Castorice, Blade, and Mydei, creating natural synergistic opportunities.

Team Building Tip: Consider pairing primary healers with secondary sustain options like March 7th for emergency cleansing or Huohuo for team-wide energy regeneration. The key is balancing healing output with enough damage to meet turn limits.

Advanced Combat Strategies and Common Pitfalls

Avoid These Critical Mistakes: Many players underestimate the importance of timing their healing cooldowns before Pollux’s Fragrance of Death state. Saving ultimate abilities for after the health reduction often results in wasted turns and potential team wipes. Instead, pre-cast area healers like Luocha’s field or Bailu’s invocations just before the mechanic triggers.

Optimal Rotation Strategy: During the Fragrance of Death sequence, prioritize healing your main damage dealer first to quickly restore team offensive capability. If using Blade or Castorice, their follow-up attacks and enhanced states can trigger even at low HP, making them priority targets for strategic healing allocation.

Advanced Weakness Breaking: While Pollux has three fixed weaknesses, the Long Arms of Sorrow summons have rotating vulnerabilities. Bring characters with overlapping elemental coverage (like Silver Wolf for implant or Welt for Imaginary breaks) to maintain break efficiency throughout the encounter.

Energy Management: Pollux’s health-draining mechanics can actually benefit energy generation for certain characters. Blade gains stacks faster, Castorice charges her ultimate quicker, and healers like Luocha generate more energy from emergency healing triggers. Plan your skill point usage around these synergies.

Common Pitfall: Many players attempt to use shielders like Gepard or Fu Xuan out of habit, forgetting that Atrophy DMG completely bypasses their protection. Always verify your sustain options before attempting this challenging encounter.
