ROSSI NUKE BUILD: TEAMS, GEAR & DPS STATS | ENDFIELD

TL;DR - Key Points

• Gilberta is BiS support – 42% Arts Susceptibility + Corrosion trigger nets ~17% more damage with battle skill timing
• MI Security + T50 YL UD% kit – Standard build, ~11% higher than Redeemer UD% gloves after team buffs
• Lupine Scarlet (signature) – ~15% more DPS than B0 Glorious Memory, B5 GM reaches near-signature tier
• Best team: Gilberta · Antal · Akekuri – F2P weapons only ~4% behind with SoM, DU, Obj: EoL
• F2P team: Perlica · Antal · Akekuri – ~20% behind best team but still very capable
• Rotation priority – Stack 4 Arts inflictions, trigger big Corrosion/Electrification before Rossi’s burst window
• Critfishing required – Last 2 Ultimate hits assumed to always crit for calc accuracy

Damage Calculation Scope

All burst damage calculations cover the following components:

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

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:

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:

Weapons

Weapon Comparison

Recommendations:

• Lupine Scarlet: If you have the signature weapon, it’s her best option for burst windows
• B0 Glorious Memory: Solid baseline, widely accessible through Battle Pass
• B5 Glorious Memory: Reaches near-signature tier — excellent if you missed Lupine Scarlet

Support Roster

Gilberta — Best-in-Slot

Provides:

• 42% Arts Susceptibility
• Triggers Corrosion debuff

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

Weapon Choice:

Pro 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.

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 Variants

★ Best Team: Gilberta · Antal · Akekuri

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

Performance: 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:

★★ 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:

Main Loss: Missing Gilberta’s massive 42% susceptibility and Corrosion ramp.

★★★ Budget Team: Perlica · Antal · Gilberta (Flex)

Weapons: SoM, Obj: AI, TC

Performance: Flexible setup that can adapt to different fight mechanics.

Use Case: When Akekuri is needed elsewhere or for fights where Link is less valuable.

DPS Comparison

Context Notes:

• BiS Team: Requires Lupine Scarlet + Gilberta signature/Obj: AI + Thermite Cutter
• F2P Teams: Use widely accessible 5★ weapons, still clear all content
• Gilberta Tax: The difference between Gilberta and Perlica teams is ~20%, showing her value
• Weapon Investment: B5 Glorious Memory closes most of the gap vs signature weapon

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 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
4. Execute burst rotation

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 (~11% better than Redeemer alternatives)
• Gilberta’s battle skill timing is critical for max damage (~17% gain)
• F2P team is only ~20% behind — still clears all content
• B5 Glorious Memory reaches near-signature performance
• Critfishing the last 2 ult hits is mandatory for calc accuracy

Investment Priority:

1. Lock in MI Security 4-piece + T50 YL UD% kit
2. Get Gilberta if possible (biggest single upgrade)
3. Level Antal and Akekuri for Link/Amp
4. B5 Glorious Memory if no Lupine Scarlet
5. Perfect rotation execution (17% free damage)
