Here is a breakdown of all three Knights, as well as recommended teams and best tips to get the maximum stars!

Knight I Knight II Knight III
4.

Knight I Stage Breakdown & Team Compositions

Knight I
Unwavering

Enemy targets' Toughness cannot be reduced, and Break DMG taken is reduced by 50%.

Knight I
Scales

Enemy targets initially have 20 stacks of this effect. Each stack reduces enemy
targets' DMG taken by 2%. Enemy targets lose 1 stack each time they are attacked.
Stacks of this effect will reset during boss enemy phase transitions.

Wave 1 - Enemy Type Weaknesses
Lighthouse Fire Wind Quantum
Decaying Shadow Fire Lightning Wind
Wave 2 - Enemy Type Weaknesses
Cocolia Fire Lightning Quantum
Lighthouse Fire Wind Quantum
4.1.

Knight I debuff blocks Super Break teams from working effectively at low cost, so we would not recommend utilizing them here. This stage has the new elite "Lighthouse", who summons adds and has a damage resistence effect until you dispel it by hitting it enough times and lowering the value to 0. It works similarly to Hoolay's mechanic, where hits from Lighthouse and its adds will increase the stack counter. Try to land as many hits as possible after Lighthouse takes his turn.

See below for recommended team setups for Knight 1:

Main DPS Support / DPS Support Sustain
Himeko • Nova Welt Mortenax Blade Dan Heng • Permansor Terrae
Ashveil Mortenax Blade Tribbie Hyacine
Evanescia Yao Guang Elation Trailblazer Huohuo
Archer Rin Tohsaka Sparkle Dan Heng • Permansor Terrae
5.

Knight II Stage Breakdown & Team Compositions

Knight II
Flow Break

Each time after an enemy target is attacked by allies, DMG taken by them decreases by 2% and CRIT DMG taken decreases by 4%, stacking up to 10 time(s). This effect changes to decreasing by 5 stack(s) after the enemy target receives a Follow-Up ATK or when Aha Instant ends.

Wave 1 - Enemy Type Weaknesses
Joy Ascendant Fire Lightning Imaginary
Rocking Rebel Physical Fire Wind
Wave 2 - Enemy Type Weaknesses
@SparxiConOfficial Fire Quantum Imaginary
5.1.

Knight II has a debuff that reduces your outgoing damage if you do not counter with follow-up attacks or Aha Instants. Knight also has a new mechanic, known as Corruption, which makes the Rocking Rebel in Phase 1 and Sparxiecon in Phase 2 gain an extra life. This stage requires a high amount of damage, so abuse the free Aha Instants that Sparxiecon gives you and try to use follow-up attacks or Aha Instants to remove Flow Break.

See below for recommended team setups for Knight 2:

Main DPS Support / DPS Support Sustain
Silver Wolf LV.999 Sparxie Yao Guang Huohuo
Sparxie Yao Guang Sparkle Dan Heng • Permansor Terrae
Ashveil Mortenax Blade Tribbie Hyacine
Evanescia Yao Guang Elation Trailblazer Huohuo
6.

Knight III Stage Breakdown & Team Compositions

Knight III
Joint Forces

DMG taken by enemy targets is reduced by 60%. When there are more than 4 ally targets
currently on the field, this effect is reduced by 20% for each additional target.

Wave 1 - Enemy Type Weaknesses
Furiae Praetor x2 Physical Fire Imaginary
Blaze Out of Space x2 Physical Quantum Imaginary
Wave 2 - Enemy Type Weaknesses
Flame Reaver of the Deepest Dark Physical Lightning Imaginary
6.1.

Knight III sees the return of Flame Reaver, this time carrying a debuff that forces you to bring Memosprites or suffer a massive damage penalty. For team building, esnure you include at least 2 Memosprites so the damage penalty is reduced to a manageable 20%. If you have a Mono-Rememberance team, here is the place to use it!

See below for recommended team setups for Knight 3:

Main DPS Support / DPS Support Sustain
Evernight Cyrene Robin • Summeretto Hyacine
Castorice Evernight Cyrene Hyacine
Aglaea Cyrene Robin • Summeretto Huohuo
Ashveil Mortenax Blade Robin • Summeretto Hyacine

King in Check Enemy Breakdown & Team Compositions

King in Check is the main boss of the Anomaly Arbitration game mode. Defeating the King provides a limited avatar frame depending on the number of stars you earn. Clearing the Plight version of the King will grant you the highest tier of avatar frame, but is incredibly difficult and only recommended for players with extremely high eidolon investments.

8.

Here is a breakdown of the King stage, as well as recommended teams and best tips to get the maximum stars.

King in Check King in Check: Plight
8.1.

King in Check Clear Requirements

In order to clear the King in Check Stage, you need to defeat the boss within the 6 provided cycles for a 1-star clear. However, for every 2 cycles left when you clear, you can earn a higher star count and a higher tier of avatar frame. If you manage to clear the King in the first cycle, you can unlock a rarer avatar frame.

Star Target Criteria
1 Star Achieve victory in no more than 6 cycles
2 Stars Achieve victory in no more than 4 cycles
3 Stars Achieve victory in no more than 2 cycles

King in Check has the following debuffs:

King
Hemovore

At the start of ally targets' turns, they lose 500 HP. This effect can be fatal.

King
Scales

Enemy targets initially have 20 stacks of this effect. Each stack reduces enemy
targets' DMG taken by 2%. Enemy targets lose 1 stack each time they are attacked. Stacks of this effect will reset during boss enemy phase transitions.

Wave 1 - Enemy Type Weaknesses
Anti-Creator, Hatred Inundate Ice Lightning Quantum

King in Check has the following buffs available which can be used alongside your team.

-
Marvelous Laughter

Increases all ally targets' Elation by 40%, and increases the All-Type RES PEN of
Elation DMG dealt by 20%. This effect is doubled when using an Elation Skill.

-
Finale's Kiss

At the start of any ally target's turn, all ally targets regenerate 25% Energy.
This effect can only be triggered 1 time per battle. Increases Skill and Ultimate
DMG dealt by all ally targets by 40%.

-
Memoria Swarm

When the number of ally memosprites is 1/2/3/4, DMG dealt by all allies increases by 20%/25%/30%/50%.

8.2.

This King stage has many powerful buffs that allow a good amount of teams to thrive. Throughout the encounter, Irontomb's adds will inflict nasty debuffs such as Action Lock and delay if you do not defeat them quickly. Defeating these adds can give energy and action advance for your team, so prioritize defeting them quickly while lowering stacks of the Scales debuff on Irontomb to deal big bursts of Damage. Cyrene will appear in the action order to occasionally grant a free ultimate as well, just like in the Story version of this fight, so make sure to utilize and play around the free ultimates. Saving Cyrene's additional skill for Phase 3 will allow you to deal big damage to Irontomb, so avoid using it in Phase 2 if you don't need to it remove Scales.

King in Check: Plight Clear Requirements

In order to clear the King in Check: Plight Stage, you need to defeat the boss within the 2 provided cycles for a full-star clear. Unlike the King in Check stage, there are no 1 or 2 star clear conditions. Clearing this version of the stage will grant you the highest rarity of avatar frame.
