Build Notes

Pogranichnik—endgame support

Rank #4

This endgame build focuses on Pogranichnik's identity as an SP-regen support. The Frontiers gear set turns every SP-restoring skill into a short team-wide damage buff, while the Bonekrusha off-piece ensures his Ultimate comes back quickly for more SP. Thermite Cutter is the weapon of choice because it boosts both his personal offense and the party's Attack, supercharging his Fervent Morale buff. The result is a support Vanguard who constantly feeds the team energy and amplifies physical damage, making him a core piece of mono-physical endgame compositions.

Thermite Cutter is the best weapon for this build because its team ATK boost directly increases the value of Pogranichnik's buffs, and the Will stat improves his SP-restoring skills.

Never Rest is a solid second option but the Physical DMG bonus it offers becomes diluted by gear bonuses across the team, so it does not help his support role as much.

Eminent Repute and Sundering Steel are fallbacks when the higher-priority weapons are unavailable; Sundering Steel only helps Pogranichnik's own damage and should be avoided if you need team utility.

The Frontiers set is ideal because it rewards the SP-restoration loop he already wants to perform, giving the party a damage window after each SP gain.

The Frontiers set reduces Combo Skill cooldown and gives the whole team +16% damage for 15s after Pogranichnik restores SP with a skill.
Using Bonekrusha Poncho T1 as an off-piece helps charge his Ultimate faster and boosts Will and Agility.
Thermite Cutter is ranked above his signature weapon because it provides team-wide ATK, making his Fervent Morale buff even stronger.

Pogranichnik—early game support

Rank #2

This early-game build gives Pogranichnik a simple, low-investment setup that still fulfills his main role as an SP-support. The Mordvolt Resistant set supplies Will, his key attribute, while Thermite Cutter offers both Will and a party ATK buff after SP restoration. It is a budget-friendly foundation that lets players use him in mono-physical teams from the very beginning, with room to transition into the frontiers endgame build later.

Thermite Cutter is listed first for early game because it provides Will and helps the party's Attack after SP restoration, which is exactly what a support Pogranichnik wants.

Sundering Steel is a decent substitute if you did not pick Thermite Cutter, but it only adds personal damage and does not enhance his team support.

Mordvolt Resistant is the best early gear because it raises Will, increasing the effectiveness of his core skills without requiring much investment.

The Mordvolt Resistant set gives +50 Will, which is Pogranichnik's main stat and directly supports his SP mechanics.
The set's low-HP treatment bonus is situational, but the stat boost alone makes it a strong early-game choice.
Thermite Cutter can be obtained alongside Pogranichnik from the New Horizons banner, making it an excellent free-to-play option.

Endministrator—endgame dps

Rank #3

This endgame build turns Endministrator into a dedicated Crush DPS. Grand Vision amps both normal attacks and Crush damage through Attack, Agility, Physical DMG, and Arts Intensity. The Grizzled Edge 4-piece then converts Crush applications and consumed Vulnerability stacks into a strong Physical DMG buff, so the character can front-load damage in Physical compositions. Rotation order matters: apply Crush after team Vulnerable stacks, use Combo Skill for Originium Crystals, and detonate them with Ultimate.

Grand Vision gives the Agility, Attack, Physical DMG, and Arts Intensity needed to fuel Crush procs and skill damage.

Grizzled Edge's set effect directly rewards the Crush playstyle and improves Physical damage output during rotations.

Choose Eminent Repute if you want to share an ATK buff with the team; Sundering Steel is the best F2P fallback.

Grizzled Edge boosts ATK and grants Physical DMG when applying Crush or Breach; the buff scales with Vulnerability stacks consumed.
In a mono Physical team, Endministrator can reliably trigger Crush at four Vulnerable stacks for maximum bonus.
Already-invested Swordmancer or Aethertech pieces can replace the Grizzled Edge gloves or one knife without losing stat value.

Endministrator—early game dps

Best in Slot

This budget build gets Endministrator going from level 15 to 30. Roving MSGR supplies flat Agility and a conditional 20% Physical DMG bonus while HP stays high. Sundering Steel is an F2P weapon that boosts Agility and Physical damage, letting the protagonist carry early content until Grizzled Edge and Grand Vision are available.

Agility is Endmin's main attribute, so Roving MSGR's flat Agility bonus is efficient before high-tier gear exists.

Sundering Steel and Prominent Edge both provide Physical DMG and Attack, covering the stats that matter most early.

Swap to Grand Vision and Grizzled Edge once you reach late game and have enough resources.

Roving MSGR is craftable early from Ferrium Components and gives +50 Agility.
At high HP, the set adds 20% Physical DMG, which suits Endmin's on-field playstyle.
Sundering Steel is a free reward from the first Operational Manual node, making this build very accessible.

Rossi—endgame dps

Rank #3

This endgame build turns Rossi into a hard-hitting sub-DPS. Lupine Scarlet supplies the mixed stats she wants, while MI Security raises her crit and attack to line up with the crit buffs from her Combo Skill. In rotations, Rossi debuffs with Razor Clawmark, converts Arts Inflictions into Vulnerability, and then detonates her Ultimate for a large Heat burst. The armor piece also improves Ultimate Gain, keeping her rotation smooth.

Lupine Scarlet is the first choice because it gives Critical Rate, Agility, Heat DMG and Physical DMG, all of which Rossi uses. Its Fracture effect stacks quickly with her multi-hit skills, especially the Ultimate.

The MI Security set adds more Critical Rate and a stacking ATK buff, which lines up with the Combo Skill's Critical Rate and Critical Damage buffs.

Glorious Memory is a solid second pick if Lupine Scarlet is unavailable, but only the Ultimate gets the Twilight bonus. Sundering Steel is the best F2P fallback, though its Physical DMG Boost does not help the Heat-based Ultimate.

Use Prominent Edge early on or as a low-cost substitute until higher rarity options appear.

MI Security's set effect raises Critical Rate and stacks ATK on crits, amplifying the crit damage bonus from Combo Skill.
Redeemer Gloves serve as an off-piece here; equip them with the two MI Security accessories to complete the set.
This build focuses on Rossi as a bursty sub-DPS who debuffs the target and then unloads her Ultimate.

Rossi—early game dps

Best in Slot

This early game build is a budget setup for new players. Sundering Steel gives a straightforward Physical damage boost and Agility, while the full Roving MSGR set adds more Agility and a conditional Physical damage increase. It makes Rossi easier to play before her crit-heavy endgame gear is available, letting her use Battle Skill and Combo Skill to apply Vulnerability and deal steady single-target damage.

Sundering Steel is the strongest F2P option early; its passive and stats align with Rossi's Physical damage phases.

Roving MSGR improves the Agility stat she needs and rewards keeping her healthy, which suits early-game fights.

Prominent Edge can be substituted if resources are tight; it offers similar Physical damage direction with lower rarity.

The full Roving MSGR set gives +50 Agility and boosts Physical DMG when HP is above 80%.
This set is meant to help Rossi clear early bosses while her crit setup is not fully available yet.
The article text names Aburrey's Legacy, but the table and set effect consistently point to Roving MSGR.

Chen Qianyu—endgame sub dps

Rank #3

This endgame sub-DPS build turns Chen Qianyu into a reliable Vulnerability engine without sacrificing her burst potential. Rapid Ascent magnifies her Ultimate damage, while the Qingbo gear pieces (Armor, Gloves, and two Positioning Kits) shorten her Combo Skill cooldown and increase Skill DMG after each Combo. Stat priority on Agility and Strength directly translates to stronger Physical damage, ensuring she can support Crush/Breach allies while still contributing meaningful personal output.

Rapid Ascent is preferred because most of Chen Qianyu's damage is concentrated in Blade Gale; the weapon's Twilight boon amplifies her burst window while Critical Rate boosts consistency.

The Qingbo set synergizes with her kit by reducing Soar to the Stars cooldown, allowing more frequent Vulnerability refreshes for the team.

Glorious Memory is a strong Protocol Pass alternative, while Sundering Steel and Aspirant are budget picks that still provide Agility and Physical DMG bonuses when the top weapons are unavailable.

Rapid Ascent's Twilight essence pairs with Chen Qianyu's Ultimate-heavy rotation, making it her strongest sword for endgame content.
The Qingbo set cuts Combo Skill cooldown and grants stacking Skill DMG after each Combo cast, improving both Vulnerability uptime and burst damage.
Prioritize Agility and Strength because they feed her main and secondary attributes and raise her Physical damage output.

Chen Qianyu—early game sub dps

Best in Slot

This early-game build pairs Sundering Steel with the Roving MSGR set to get Chen Qianyu off the ground quickly. The set's flat Agility bonus and Physical DMG condition work cleanly with her Lift-based rotation, while Sundering Steel adds more Physical DMG and Agility. It is a budget-friendly path that still allows her to apply Vulnerability and deal meaningful damage before transitioning to Qingbo.

Sundering Steel is the early-game pick because it combines Physical DMG Boost, Agility Boost, and the Combative effect, all of which Chen Qianyu can use from the moment she joins the roster.

The Roving MSGR jacket, fists, and gyro pieces are easy to acquire and give her Agility plus a Physical DMG buff when she keeps her HP high.

Once players can farm Rapid Ascent or Glorious Memory with Qingbo gear, they should swap off this starter setup for the endgame build.

Roving MSGR provides flat Agility and a conditional Physical DMG boost while HP stays above 80%, matching Chen Qianyu's early stat needs.
Both Roving MSGR Gyro pieces grant bonus Attack, making this set especially easy to slot in during progression.
This build is low-investment and lets her contribute Vulnerability stacks before the Qingbo endgame pieces are farmed.
