## 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

## 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
