Build Notes

Chen Qianyu — endgame sub dps

Rank #2

This endgame sub-DPS build maximizes Chen Qianyu’s Vulnerability application and burst potential. Rapid Ascent turns her low-cost Ultimate into a hard-hitting tool, while Swordmancer gear adds consistent stat boosts and a triggered Physical hit that further accelerates Stagger. The Bonekrusha armor piece rounds out her energy economy, ensuring she can cycle abilities quickly. Use this setup when you need a reliable Physical enabler who also contributes significant burst damage.

Rapid Ascent is chosen because Chen Qianyu’s largest damage source is her Ultimate; the weapon amplifies it and shores up her crit consistency.

Swordmancer pieces directly enhance her key stats (Agility, Strength) and Physical DMG, while the set bonus synergizes with her constant Physical status application (Lift → Vulnerability).

Bonekrusha armor acts as an off-set piece that improves energy recharge and Combo Skill damage, giving her more frequent and powerful full rotations.

Sundering Steel and Aspirant serve as strong f2p alternatives, providing reliable Agility and Physical bonuses with easier activation conditions.

Rapid Ascent substantially increases Blade Gale's damage and provides a welcome crit rate boost.
Swordmancer set pieces raise Agility and Strength, and the 2-piece effect deals a burst of Physical DMG on status application while making Stagger more frequent.
Bonekrusha armor reinforces Ultimate Gain Efficiency and Combo Skill DMG, aligning with her burst-oriented playstyle.

Chen Qianyu — early game sub dps

Best in Slot

A reliable early‑game build that leverages Roving MSGR’s agility-centric bonuses and Sundering Steel’s synergy with Physical damage. It ensures Chen Qianyu remains effective as a sub‑DPS/Vulnerability applier until you can transition to the more specialized Swordmancer/Bonekrusha endgame configuration.

Sundering Steel is the go‑to early weapon because it directly raises Agility and gives a Physical DMG multiplier, both essential for Chen Qianyu’s damage output.

The Roving MSGR set is easily obtainable and focuses on raw Agility, plus a conditional Physical DMG buff that is straightforward to maintain during early‑game content.

This combination gives a balanced mix of base stats and damage bonuses while you work toward the endgame Swordmancer setup.

Sundering Steel offers an easy-to-activate Agility and Physical DMG boost that works well with Chen Qianyu’s kit.
Roving MSGR set provides a large flat Agility bonus and extra Physical DMG when HP is high, perfect for early progression.

Endministrator — endgame dps

Rank #3

This endgame Crush DPS build focuses on amplifying Endministrator's Physical DMG and Crush procs. Grand Vision significantly enhances Agility and Arts Intensity, while the Swordmancer set raises relevant primary stats and adds a bonus burst of Physical DMG when applying a Physical Status. Together, they allow Endmin to devastate enemies by quickly stacking and detonating Crush. This setup shines in teams that can sustain high Vulnerable uptime, enabling rapid and powerful Crush activations.

Grand Vision is chosen for its Agility, Attack, Physical DMG, and Arts Intensity buffs, directly boosting Crush potency.

Swordmancer set provides Agility and Strength while its set effect deals extra Physical DMG when a Physical Status is applied, synergizing with Endmin's Crush.

Aethertech Gloves serve as an off-piece to further increase Arts Intensity, enhancing Crush damage.

Eminent Repute offers team utility with an Attack buff; Sundering Steel is a strong free option for early progression.

Maximizes Crush damage through high Agility, Arts Intensity, and Physical DMG bonuses.
Ideal for mono-Physical setups where Vulnerable stacks are consistently applied.

Endministrator — early game dps

Best in Slot

This early game build prioritizes Agility and Physical DMG to get Endministrator through the opening hours. Sundering Steel is a reliable free weapon with relevant offensive stats, and the Roving MSGR set is quickly crafted using Ferrium components. Together they provide a noticeable damage boost while you farm for the more powerful Swordmancer set and Grand Vision. This setup is ideal for players who want a smooth leveling experience without investing heavily in early game resources.

Sundering Steel is obtainable early via the Operational Manual and boosts Agility and Physical DMG, directly enhancing Endmin's damage.

Roving MSGR set grants a large Agility bonus and conditional Physical DMG, covering essential stats without relying on rare drops.

If another Agility weapon like Prominent Edge is acquired, it can serve as a substitute until Sundering Steel is upgraded.

Simple to gear with easily craftable Roving MSGR pieces and the free Sundering Steel.
Adequate to carry you through early story content until better gear becomes available.

Pogranichnik — early game support

Rank #2

This early game build prioritizes survivability and Will stacking. The Mordvolt Resistant set grants a hefty +50 Will and emergency treatment effect, keeping Pogranichnik effective while leveling. Thermite Cutter offers easy access from the New Horizons banner and boosts team damage significantly, making it the ideal weapon. As you transition to endgame, focus on acquiring Frontiers pieces to unlock his full buffer potential.

Mordvolt Resistant is the best starting gear as it amplifies Will, which is Pogranichnik's primary stat for his buffs and damage.

Thermite Cutter's ability to increase the entire party's ATK makes it indispensable even in early content, while its Will substats further enhance his kit.

If you selected a different weapon, Sundering Steel can cover physical damage output but will not provide the same team utility.

Mordvolt Resistant set provides a significant Will boost, directly increasing Pogranichnik's support ability and personal damage.
Thermite Cutter remains the best early choice due to its team ATK buff, obtained alongside Pogranichnik from the New Horizons banner.
Sundering Steel is a fallback option if you didn't choose Thermite Cutter; it offers personal DPS but lacks team support.

Rossi — endgame sub dps

Rank #3

This endgame build turns Rossi into a crit‑focused hybrid sub‑DPS. By stacking critical rate from the MI Security set and Lupine Scarlet, she consistently triggers her Combo Skill’s critical damage buff, amplifying both her own and her team’s output. The gear pieces further enhance her Ultimate damage and energy gain, allowing smoother rotations. Alternative weapons like Glorious Memory can substitute if Lupine Scarlet is not acquired, though crit rate remains the top priority.

Lupine Scarlet is chosen because it provides a large critical rate boost and ramping Physical/Heat DMG%, perfect for Rossi’s dual-element attacks.

The MI Security set grants stacking critical rate and ATK after scoring critical hits, aligning with her need to crit often.

Glorious Memory offers comparable crit rate and DMG% when applying Vulnerability, making it a strong alternative from the battle pass.

Sundering Steel and Wave Tide lack crit rate but are solid early or F2P options if the higher-rarity weapons are unavailable.

Maximizes critical rate to fully exploit the critical damage buff from Moment of Blazing Shadow.
Lupine Scarlet stacks Physical and Heat DMG% on critical hits, synergizing with her hybrid kit.
Redeemer Gloves off‑piece boosts Ultimate DMG, her hardest‑hitting ability.

Rossi — early game sub dps

Best in Slot

Tailored for players building Rossi early on, this setup emphasizes Agility and Combo Skill damage. The Aburrey’s Legacy set enhances all skill types, while Sundering Steel provides consistent ATK boosts. It serves as a reliable bridge until higher-crit gear and weapons become accessible.

Sundering Steel is the best 4‑star option because it grants ATK% and further ATK when dealing Physical Statuses, which Rossi applies often.

The Aburrey’s Legacy set increases skill damage and grants extra ATK after casting any skill, directly amplifying her Combo Skill and Ultimate.

Roving MSGR Fists offer a flat ATK bonus, a valuable stat for early progression.

Provides a strong early-game foundation by boosting Combo Skill damage and Agility.
Sundering Steel’s ATK buff on Physical Status application fits Rossi’s frequent skill usage.
