Gear Sets

Standard Build — MI Security + T50 YL UD% Kit

The best usual choice for Rossi nuke builds. After accounting for team buffs, this setup is around 11% higher than MI Security + Redeemer UD% gloves.

Configuration:

• Armor: MI Security 4-piece set
• Kit: T50 Yinglung with UD% (Ultimate Damage%) kits
• Gloves: T50 Yinglung with UD% kits

High Ceiling Build — T50 YL + Redeemer UD% Gloves

Can be 1-4% higher depending on team buffs, but requires even more critfishing to reach potential.

Configuration:

• Armor: T50 Yinglung with Agi+Int Armor pieces
• Kits: UD% kits on all pieces
• Gloves: Redeemer set with UD% kits

Weapons

Lupine Scarlet (Signature Weapon)

Rossi’s signature weapon provides approximately 15% more DPS for nuke builds compared to B0 Glorious Memory (Battle Pass weapon).

When to use: If you have the weapon, it’s her best option for burst windows.

Glorious Memory (Battle Pass)

A solid option for nuke builds, especially at higher refinements.

• B0: Solid baseline, widely accessible
• B5: Reaches near-signature tier performance

Recommendation: If you missed Lupine Scarlet, B5 Glorious Memory is your next best option.

Support Roster

Gilberta — Best-in-Slot

Provides:

• 42% Arts Susceptibility
• Triggers Corrosion debuff

Setup: Run her on HW (High Wisdom) full AI build.

Tip: Trigger Corrosion with her battle skill, not her ultimate. This lets the debuff fully ramp before Rossi’s burst window, netting approximately 17% more damage.

Weapon choice: Her signature is slightly worse here than 5★ Obj: AI (B5), since Obj: AI grants almost the same DMG% plus 62 AI for Corrosion. She can also wield Stanza if no one else can (outside whale setups, Stanza is mandatory on someone).

Antal — Amplifier

Provides:

• 22% Amp
• 14% Arts Susceptibility
• Enables easier Arts infliction stacking

Setup: Runs EX (Expertise) set.

Weapon options: Detonation Unit, Obj: AI, or SoM (Stanza of Melodies).

Akekuri — Link

Provides:

• 10% ATK
• Link (1.2× multiplier)
• Frontiers set bonus

Best weapon: Thermite Cutter, but Obj: EoL (B5) is not far behind.

Perlica — Debuffer

Provides:

• Electrification (~29% Arts damage taken increase)

Setup: Run full AI, usually wielding SoM.

Flex options: Can swap to Detonation Unit or Obj: AI when she handles Arts inflictions instead of buffering.

Team Rankings

Best Team: Gilberta · Antal · Akekuri

Weapons: SoM, DU, and TC (Thermite Cutter)

Performance: This is the current ceiling for Rossi nuke builds.

F2P comparison: F2P weapons (Obj: AI + SoM + Obj: EoL) are only ~4% behind the signature weapon setup.

Why it works: Gilberta’s 42% Arts Susceptibility combined with Corrosion creates the largest vulnerability window. Antal provides Amp and additional susceptibility. Akekuri’s Link multiplier scales with Rossi’s already high base damage.

F2P Team: Perlica · Antal · Akekuri

Weapons: SoM, Obj: AI, Obj: EoL

Performance: Approximately 20% behind the best team, but still very capable of clearing all content.

Why it works: Perlica’s Electrification provides consistent Arts vulnerability. Antal and Akekuri provide the same buffs as the premium team. The main loss is Gilberta’s massive 42% susceptibility and Corrosion ramp.

Rotation Priority

The core goal is to stack 4 Arts inflictions and trigger big Corrosion (or Electrification without Gilberta), while aligning all team and community buffs before Rossi’s burst window.

With Gilberta:

1. Stack Arts inflictions on target
2. Use Gilberta’s battle skill to proc Corrosion (not ultimate)
3. Wait for debuff to fully ramp
4. Execute Rossi’s burst rotation

Why battle skill over ultimate: Using the battle skill lets the Corrosion debuff have time to fully ramp before Rossi’s burst window. This timing nets approximately 17% more damage compared to using her ultimate.

Without Gilberta:

1. Stack Arts inflictions on target
2. Trigger Electrification via Perlica
3. Align all buffs and execute burst

Damage Calculation Scope

All burst damage calculations cover:

• Seething Blood (Talent damage component)
• Ultimate 1 (Multihit portion)
• Ultimate 2 (250% multiplier)
• Ultimate 3 (750% multiplier)

Assumption: Last two Ultimate hits are assumed to always crit — critfishing (reset until crits land) is baked into the numbers for accuracy.

Summary

Rossi remains one of the strongest burst DPS options in Arknights: Endfield. While her signature weapon and Gilberta support provide the highest ceiling, F2P alternatives are remarkably close in performance.

Key takeaways:

• MI Security + T50 YL UD% is the reliable standard
• Gilberta’s battle skill timing is critical for max damage
• F2P team is only ~20% behind — still clears all content
• Critfishing the last 2 ult hits is mandatory for calc accuracy
