Build Notes

Chen Qianyu — endgame sub dps

Rank #2

This endgame build maximizes Chen Qianyu's potential as a Vulnerability sub‑DPS. Rapid Ascent empowers her Ultimate burst, while the Swordmancer gear set (with a Bonekrusha armor piece for extra Combo DMG) stacks Agility, Strength, and Physical DMG bonuses. The combined effects of her skills and gear ensure frequent Lifts, additional Physical hits, and rapid Stagger breaks, letting your main DPS capitalize on extended Vulnerability windows.

Rapid Ascent is the best weapon because its Twilight essence greatly increases Blade Gale's damage against Staggered enemies, perfectly aligning with Chen Qianyu's role.

The Swordmancer set provides Agility and Strength stats, critical for her scaling, and its bonus attack on Physical Status application synergizes with her sustained Lift loops.

Alternative sets like Bonekrusha can work if you need more Battle Skill damage, but Swordmancer remains top for overall consistency and Stagger efficiency.

Focus on Agility and Strength to boost both ATK and Physical skill damage; secondary priority is Physical DMG Bonus.
The mixed set (Bonekrusha armor + Swordmancer pieces) offers strong Combo‑ and Ultimate‑DMG bonuses while retaining the Swordmancer 2‑piece bonus that enhances Stagger and adds a bonus Physical attack.

Chen Qianyu — early game sub dps

Best in Slot

A straightforward early-game setup that focuses on Agility and Physical DMG. Sundering Steel offers consistent ATK increases through Physical Status applications, while the Roving MSGR set amplifies her main stat and adds a conditional Physical DMG bonus. Use this build to smoothly progress through early and mid‑game content before transitioning to endgame gear.

Sundering Steel is the most accessible early-game sword that directly buffs Physical DMG and ATK, matching her damage profile and skill patterns.

The full Roving MSGR set is easy to obtain and provides a massive Agility boost, plus Physical DMG bonus that works as long as you manage her HP well.

This setup bridges the gap until you can farm higher‑tier gear and weapons like Rapid Ascent and Swordmancer.

At early levels, prioritize Agility above all else; the Roving MSGR set grants a flat +50 Agility and +20% Physical DMG when HP is above 80%.
Sundering Steel’s Combative essence provides a sizable ATK buff after dealing Physical Status, which Chen Qianyu can activate frequently with her Battle and Combo Skills.

Endministrator — endgame dps

Rank #3

This endgame build maximises Endministrator’s role as a Physical DPS and vulnerability consumer. Eminent Repute’s team‑wide ATK buff turns every Vulnerability cycle into a party damage spike, while the Swordmancer set with a Bonekrusha Mask accelerates stagger application and amplifies damage against weakened foes. The stat priority focuses on Agility for Main Attribute scaling, Strength for secondary attack, and Physical DMG bonuses, ensuring consistent high output. Grand Vision is an optimal personal damage alternative if team buffing is less important.

Eminent Repute is chosen over Grand Vision for its strong team buff – allies receive half the ATK increase, effectively raising total party DPS in Physical‑focused compositions.

The weapon’s essences (ATK%, Physical DMG, Agility) directly amplify Endministrator’s scaling, while the passive aligns with their frequent Vulnerability consumption.

Grand Vision excels for solo carry scenarios where personal burst damage is prioritised, but the team-wide support from Eminent Repute is generally superior in group play.

Sundering Steel serves as a reliable F2P alternative that still grants ATK, Physical DMG, and Agility, but falls behind premium options in raw numbers.

Eminent Repute provides a team‑wide ATK buff after consuming Vulnerability, enhancing party damage beyond personal output.
Grand Vision offers the highest personal Physical DMG boost and fits Endministrator’s kit thematically, but lacks the team utility of Eminent Repute.
Swordmancer set greatly increases stagger efficiency, creating more damage windows during enemy weakened states.
Bonekrusha Mask further boosts damage against staggered enemies, synergising with the playstyle.

Endministrator — early game dps

Best in Slot

Tailored for players progressing through the initial chapters, this early game build uses readily obtainable gear and weapons to establish a solid Physical DPS line. Sundering Steel’s straightforward stat boosts ensure Endministrator hits hard, while the Roving MSGR set provides a comfortable mix of stats and conditional damage. Together they allow smooth progression until transitioning to endgame options like Swordmancer and Eminent Repute.

Sundering Steel’s essences directly boost ATK and Physical DMG, with the Agility boost raising Main Attribute – the core scaling for Endministrator.

Easy availability of duplicates allows early max refinement, making it stronger than most early alternatives.

Roving MSGR pieces enhance Agility and offer flat Physical DMG Bonus when HP is high, which is easy to maintain with basic healing.

Flashlight and Gyro extend combo skill damage and attack %, synergising with Endministrator’s skill rotation in early content.

Sundering Steel is a strong F2P sword that provides ATK, Physical DMG, and Agility – perfectly complementing Endministrator’s early needs.
The Roving MSGR set grants Agility and conditional Physical DMG, and can be assembled early without rare drops.
This setup remains effective until you can farm the endgame Swordmancer set and acquire a premium weapon.

Pogranichnik — early game support

Rank #2

This budget build focuses on easy access to SP recovery tools and a strong Will stat. Thermite Cutter gives a team ATK boost after every SP restore, while the Mordvolt Resistant set shores up survivability and main attribute scaling. It serves as a solid foundation before upgrading to the Frontiers endgame loadout.

Thermite Cutter is the best early weapon because its Flow essence grants a party‑wide ATK buff after SP recovery, mimicking the endgame weapon’s support pattern without needing heavy investment.

The Mordvolt Resistant set is chosen for its immediate Will stat increase, Pogranichnik’s main attribute, and the conditional healing effect can help in prolonged fights.

Sundering Steel is a fallback option that boosts personal damage when inflicting Physical Statuses, but it lacks team buffs and is less effective for a support role.

A beginner‑friendly setup that emphasizes Will and early SP regeneration.
Mordvolt Resistant set provides a flat Will boost and extra healing when below 50% HP.
Thermite Cutter is easily obtainable from the New Horizons banner and offers a straightforward team ATK buff.

Rossi — endgame sub dps

Rank #3

This endgame build maximizes Rossi's damage potential by stacking critical rate to trigger Lupine Scarlet's powerful buff. The MI Security set further amplifies crit rate and attack, while Redeemer Gloves strengthen her Ultimate. The result is a sub-DPS who can deal massive consistent damage while debuffing enemies.

Weapon: Lupine Scarlet boosts both Physical and Heat damage on crit, stacking up to huge bonuses after 16 crits. It synergizes perfectly with Rossi's Combo Skill crit buffs.

Gear: MI Security set increases crit rate and attack on crit, multiplying with the weapon. Redeemer Gloves boost her high-impact Ultimate damage.

Alternatives: Glorious Memory can replace Lupine Scarlet if you prefer ultimate-focused damage, but requires constant Vulnerability application. Sundering Steel and Wave Tide are fallback options but lack crit rate, dropping damage significantly.

Best Endgame Set: MI Security with Redeemer Gloves provides high crit rate and ultimate damage, fully utilizing Rossi's crit buffs.
Alternative gear: Frontiers Armor T2 + MI Security Gloves T1 yields even higher damage but sacrifices Ultimate Gain.

Rossi — early game sub dps

Best in Slot

A beginner-friendly build that concentrates on boosting Rossi's combo skill damage and agility. Sundering Steel and the Aburrey set provide solid attack and skill damage multipliers, making her effective in early content while lacking critical rate.

Weapon: Sundering Steel increases ATK and Physical damage, and its conditional ATK boost on dealing Physical Status aligns well with Rossi's kit.

Gear: Aburrey's Legacy set buffs combo skill damage and provides extra attack when using skills, suiting Rossi's playstyle perfectly. Roving MSGR Fists add more attack.

This setup focuses on raw damage output until you can farm MI Security and obtain crit weapons.

Ideal for early progression before unlocking crit-focused gear.
Sundering Steel provides a straightforward ATK and Physical DMG boost that benefits all attacks.
