How to Clear HSR Anomaly Arbitration Stage
Anomaly Arbitration isn’t particularly friendly to free-to-play players. You’ll need teams that are not only strong but also well-equipped with the best builds available. Additionally, character Constellations might come in handy.
Let’s break down effective strategies for each stage so you can collect those valuable rewards.
First Stage: Knight
The first Knight you encounter has specific traits and weaknesses:
- Resilient Armor: Starts with 2 stacks of “Resilient Armor,” reducing damage taken by 15% per stack. Each Toughness reduction to 0 removes one stack of this armor.
- Weakness: Imaginary and Fire
To efficiently tackle this stage, bring Break teams to consistently weaken your enemy. Here are some suggested line-ups:
| DPS | Support | Support | Sustain |
|---|---|---|---|
| Firefly / Rappa | Fugue | Ruan Mei | Lingsha / Gallagher |
| Mydei | Sunday / Bronya | Tribbie | Luocha |
| Dan Heng Imbibitor Lunae | Sparkle | Sunday | Gallagher |
Second Stage: Knight
The second Knight presents a different set of challenges:
- Tempering: Reduces Crit DMG dealt to them by 3% for every 1% HP they lose.
- Weakness: Physical, Wind, and Lightning
Hypercarry teams focusing on crit builds will struggle here; instead, consider DoT or Break teams. Here’s a look at effective team compositions:
| DPS | Support | Support | Sustain |
|---|---|---|---|
| Boothill | Fugue | Ruan Mei | Lingsha / Gallagher |
| Hysilens | Kafka | Black Swan | Huohuo / Dan Heng Permansor Terrae |
| Phainon | Sunday / Bronya | Cerydra | Dan Heng Permansor Terrae |
| Feixiao | Cipher / Tribbie | Robin | Dan Heng Permansor Terrae |
Third Stage: Knight
In the third stage, you will face the most formidable Knight yet, who possesses two powerful traits:
- Inversion: Each attack causes the attacker to lose 2% of their Max HP (non-fatal).
- Under Protection: Non-elite enemies can’t have their HP and Toughness reduced.
- Weakness: Quantum and Physical
This boss favors single-target DPS units due to the limitations placed on non-elite enemies. Swiftly eliminate Elite targets for a sustainable strategy. Recommended line-ups include:
| DPS | Support | Support | Sustain |
|---|---|---|---|
| Castorice | Tribbie / RMC | Evernight | Hyacine / Lingsha |
| Archer | Sparkle | Cipher | Hyacine / Dan Heng Permansor Terrae |
| Phainon | Sunday / Bronya | Cerydra | Huohuo / Gallagher |
| Seele | Sunday | Bronya | Huohuo |
Fourth Stage: King
Finally, the King awaits you after all Knights have been defeated, posing the strongest challenge:
- Inversion: Each attack results in 2% Max HP loss (non-fatal).
- Energy Absorption: Attacks reduce the attacker’s Energy unless at max.
- Sunder: Inflicts HP loss stacks on being attacked.
- Weakness: Quantum, Physical, Ice
This stage demands your strongest strategies. Health-draining teams can be effective, along with a solid healer to manage the HP loss from attack mechanics. Consider these teams:
| DPS | Support | Support | Sustain |
|---|---|---|---|
| Castorice | Tribbie / RMC | Evernight | Hyacine |
| Hysilens | Kafka | Tribbie | Hyacine / Huohuo |
| The Herta | Anaxa | Tribbie | Hyacine |
| Argenti | Sunday | Tingyun | Huohuo |
