Understanding Anomaly Arbitration Stages
The Anomaly Arbitration endgame mode consists of four distinct stages, each with unique mechanics and challenges. Understanding these stages is crucial for success in this difficult content.
Stage Structure
- Three Knight Stages: These are trial stages that must be cleared with three different teams
- One King Stage: The final boss battle that can be challenged with any team
- Cycle Limits: Each combat has a specific action limit; exceeding it results in failure
- Star Ratings: Earn stars based on completion speed and specific conditions
Knight Stages Overview
The three Knight stages serve as preliminary challenges that weaken the final King boss. Each Knight stage has:
- Unique Enemy Traits: Special mechanics that affect battle strategy
- Specific Weaknesses: Element types that deal increased damage
- Independent Star Ratings: Each stage is rated separately
- Team Restrictions: Must use different character teams for each stage
King Stage Overview
The King stage represents the ultimate challenge in Anomaly Arbitration, featuring:
- Enhanced Mechanics: More powerful versions of Knight stage abilities
- Arbitral Quadrant Buffs: Optional buffs to help your team
- Two Difficulty Levels: Normal and Plight (harder mode with better rewards)
- Cycle Pressure: Tight action limits requiring optimal play
Knight Stage 1: Resilient Armor Challenge
The first Knight stage introduces players to Anomaly Arbitration mechanics with the Resilient Armor trait. This stage tests your ability to break enemy toughness quickly and consistently.
Enemy Traits and Weaknesses
Resilient Armor: Enemy targets start with 2 stacks of “Resilient Armor,” with each stack reducing damage taken by 15%. Enemies lose 1 stack each time their Toughness is reduced to 0.
Weaknesses: Imaginary and Fire elements deal increased damage to enemies in this stage.
Best Teams for Knight Stage 1
Break teams excel in this stage due to the Resilient Armor mechanic. Here are the most effective team compositions:
| DPS | Support | Support | Sustain |
| Firefly | Fugue | Ruan Mei | Lingsha |
| Rappa | Fugue | Ruan Mei | Gallagher |
| Mydei | Sunday | Tribbie | Luocha |
Strategy Tips
- Focus on characters who can quickly reduce enemy toughness
- Use break effect builds to maximize damage output
- Prioritize Imaginary and Fire damage dealers
- Consider using characters with multi-hit abilities to break toughness faster
Knight Stage 2: Tempering Mechanics
Knight Stage 2 introduces the Tempering trait, which directly counters critical damage builds. This stage requires players to think outside the box and use alternative damage strategies.
Enemy Traits and Weaknesses
Tempering: For every 1% HP the enemy target loses, critical damage dealt to them is reduced by 3%. This makes critical damage builds increasingly ineffective as the battle progresses.
Weaknesses: Physical, Wind, and Lightning elements work well against these enemies.
Best Teams for Knight Stage 2
DoT (Damage over Time) teams perform exceptionally well in this stage since they don’t rely on critical damage:
| DPS | Support | Support | Sustain |
| Hysilens | Kafka | Black Swan | Huohuo |
| Boothill | Fugue | Ruan Mei | Lingsha |
| Castorice | Evernight | Tribbie | Hyacine |
Strategy Tips
- Avoid characters who rely heavily on critical damage
- DoT effects bypass the Tempering mechanic effectively
- Consider using break teams as an alternative strategy
- Focus on consistent damage rather than burst damage
Knight Stage 3: Inversion and Protection
Knight Stage 3 presents the most complex mechanics among the Knight stages, combining health loss mechanics with protection effects that change targeting priorities.
Enemy Traits and Weaknesses
Inversion: Each time after the enemy target is attacked, the attacker loses HP equal to 2% of their own Max HP. This effect is non-fatal.
Under Protection: Non-elite enemy targets won’t have their HP and Toughness reduced, and their Effect RES is increased by 100%. When all elite enemies are defeated, remaining enemies are also eliminated.
Weaknesses: Quantum and Physical elements are most effective here.
Best Teams for Knight Stage 3
Single-target DPS units excel in this stage due to the Under Protection mechanic:
| DPS | Support | Support | Sustain |
| Phainon | Sunday | Cerydra | Gallagher |
| Castorice | Evernight | Tribbie | Hyacine |
| Archer | Sparkle | Cipher | Aventurine |
Strategy Tips
- Focus on eliminating elite enemies first to clear the stage faster
- Use characters with self-healing or health drain abilities
- Single-target DPS is more valuable than AoE in this stage
- Consider using shields to mitigate the Inversion mechanic’s health loss
King Stage: The Ultimate Challenge
The King stage represents the culmination of Anomaly Arbitration, featuring multiple complex mechanics that test every aspect of team building and gameplay skill.
Enemy Traits and Weaknesses
Inversion: Each time after the enemy target is attacked, the attacker loses HP equal to 2% of their own Max HP. This effect is non-fatal.
Energy Absorption: After an enemy target receives an attack, the attacker’s Energy is reduced by 2 points, except when the attacker’s Energy is maxed. When an enemy is defeated, the attacker regenerates 10 Energy.
Sunder: When allies are attacked, they receive the “Sunder” effect. Each stack causes the holder to lose HP equal to 0.8% of their Max HP. This effect stacks indefinitely and cannot be dissipated. After targets with “Sunder” receive a Shield or healing, all “Sunder” effects are dispelled on both targets.
Weaknesses: Quantum, Physical, and Ice elements are recommended for this stage.
Arbitral Quadrant Buffs
Before challenging the King, you can select one of three helpful buffs:
- Think Outside the Box: When the number of allies on field doesn’t equal 4, increases all allies’ DMG by 60%
- Infantry and Cavalry: Whenever any ally uses their Ultimate, ignores 40% of target’s DEF. After Ultimate deals DMG, the next Skill ignores 40% of target’s DEF
- Hammer and Anvil: After receiving Shield effects or healing, DMG taken is reduced by 25%, and All-Type RES PEN is increased by 20% for 2 turns
Best Teams for King Stage
| DPS | Support | Support | Sustain | Recommended Buff |
| Castorice | Tribbie | Evernight | Hyacine | Think Outside the Box |
| Hysilens | Kafka | Tribbie | Huohuo | Hammer and Anvil |
| The Herta | Anaxa | Tribbie | Hyacine | Infantry and Cavalry |
Strategy Tips
- Choose your Arbitral Quadrant buff based on your team composition
- Characters with energy generation help counter the Energy Absorption mechanic
- Healing and shielding are essential to manage the Sunder effect
- Consider using characters with health drain abilities to offset the Inversion mechanic

Frequently Asked Questions
How do I unlock Anomaly Arbitration in Honkai Star Rail?
To unlock Anomaly Arbitration, you must complete Memory of Chaos Stage 12, Pure Fiction Stage 4, and Apocalypse Shadow Stage 4 with 3-star ratings.

What are the best teams for Anomaly Arbitration stages?
The best teams vary by stage due to different enemy mechanics. For Knight Stage 1, break teams with characters like Firefly, Rappa, or Mydei work best. Knight Stage 2 favors DoT teams featuring Hysilens, Kafka, or Castorice due to the Tempering mechanic. Knight Stage 3 requires single-target DPS units like Phainon or Archer to handle the Under Protection mechanic. The King stage needs well-rounded teams with strong sustain, such as Castorice with Tribbie and Hyacine, or Hysilens with Kafka and Huohuo. Each stage requires specific team compositions tailored to its unique challenges.
Is Anomaly Arbitration worth the difficulty?
Anomaly Arbitration is worth attempting if you’re seeking the ultimate challenge in Honkai Star Rail and have exhausted other endgame content. While it doesn’t offer Stellar Jade rewards, it provides valuable resources like Lone Stardust, Self-Modeling Resin, and Interference Keys. More importantly, it offers exclusive cosmetic rewards like avatar frames for clearing the Plight difficulty. The mode is specifically designed for veteran players who want to test their account strength and strategic thinking. If you enjoy difficult content and have strong character investments, Anomaly Arbitration provides a satisfying endgame goal.
What rewards do you get from Anomaly Arbitration?
Anomaly Arbitration offers several valuable rewards despite not including Stellar Jade. You can earn Lone Stardust, which can be exchanged for items in the Gift of Stardust store. Self-Modeling Resin rewards allow you to select specific relic stats when farming. Interference Keys block unwanted stats when rerolling relics using Variable Dice. Additionally, clearing the Plight difficulty grants exclusive avatar frames as cosmetic rewards. The rewards are distributed based on star ratings achieved in each stage, with more stars granting better rewards. While not as immediately valuable as Stellar Jade, these resources significantly aid in character progression and relic optimization.
How often does Anomaly Arbitration reset?
Anomaly Arbitration resets every six weeks, typically on Wednesday after a version update maintenance. Each new phase introduces fresh stage layouts, enemy compositions, and updated Arbitral Quadrant buffs. The reset schedule allows players to attempt new challenges and earn fresh rewards. For example, the current phase is active until November 5, 2026, when the next phase will begin. Understanding the reset schedule is crucial for planning your attempts and maximizing rewards before the content refreshes. The six-week cycle gives players ample time to prepare strategies and build appropriate teams for each new phase.
Do I need specific characters to clear Anomaly Arbitration?
While having specific characters makes Anomaly Arbitration easier, it’s possible to clear the content with various team compositions. The key is understanding each stage’s mechanics and building teams that counter those specific challenges. For example, break characters excel in Knight Stage 1, while DoT characters dominate Knight Stage 2. However, many characters can fill similar roles within their respective categories. The mode is designed to test strategic thinking rather than requiring specific “meta” characters. That said, having a diverse roster with different elements and playstyles significantly increases your chances of success across all stages.
What’s the difference between normal and Plight difficulty in Anomaly Arbitration?
The Plight difficulty in Anomaly Arbitration represents a harder version of the King stage with enhanced mechanics and better rewards. In Plight difficulty, enemy traits are amplified, for example, the Inversion mechanic increases from 2% to 3% Max HP loss per attack, and Energy Absorption increases from 2 to 4 energy points drained. The Sunder effect also increases from 0.8% to 1.6% Max HP loss per stack. While significantly more challenging, clearing Plight difficulty grants exclusive avatar frames that aren’t available in normal mode. Plight difficulty is intended for players seeking the ultimate challenge and who have mastered the normal version of Anomaly Arbitration.
