BISLupine Scarlet

100.00% solo · 100.00% in team at P0

Lupine Scarlet, Rossi's Signature Weapon, is her best option for Agility, Critical Rate and a large DMG% boost, but has downtime and needs Basic Attacks timed carefully to max its stacks before they reset every 20 seconds.

#2Glorious Memory

88.70% solo · 92.50% in team at P5

Glorious Memory, Rossi's weaker Battle Pass Signature, buffs Ultimate DMG per Vulnerable stack up to 3 per rotation but skips Basic Attack and Combo Skill damage, beating listed numbers in one-shot, no-downtime fights.

#3Sundering Steel

68.90% solo · 79.40% in team at P5

Sundering Steel's passive is strong but its lack of Critical Rate can cost key crits given her kit's boosted Critical DMG, though her Battle and Combo Skills both apply Lift to trigger the passive and keep both stacks up easily.

#4Umbral Torch

67.00% solo · 78.10% in team at P5

Umbral Torch, Laevatain's Battle Pass weapon, works on Rossi via its 6-star stat line without her Primary Attribute, with high ATK and a Heat DMG passive boosting Ultimate with steady Combustion or Corrosion, rating better in Ardelia teams.

#5Rapid Ascent

64.00% solo · 76.10% in team at P0

Rapid Ascent, a 6-star with Critical Rate, boosts Battle Skill's Physical DMG, but since Ultimate isn't Physical only its DMG vs Staggered buff helps, dropping off unless she ults Staggered foes, beating listed numbers in short fights.

CoreMI Security

MI Security is a go-to for crit-scaling Operators, stacking Critical Rate on its pieces and adding 25% ATK plus 10% Critical Rate on consistent crits, suiting Rossi's Critical DMG kit, Talent extra hits, and preferred Agility and Intellect.

3PC3-piece set effect: Wearer's Critical Rate +5%. After the wearer scores a critical hit, the wearer gains ATK +5% for 5s. This effect can reach 5 stacks. At max stacks, grant an additional Critical Rate +5%. This effect cannot stack.

Origin of Admiration

102.3% solo101.5% in team

Raising both Battle and Combo Skill multipliers at once is solid for a Potential, since most give only one, though it mainly aids sustained damage given how much of Rossi's output comes from Ultimate and Talents, with a minor SP return.

In gameBattle skill Crimson Shadow and combo skill Moment of Blazing Shadow improved: The DMG Multipliers of these skills are increased to 1.15 times of the original. Wolven Ambrage of the battle skill also returns 10 SP after hitting the enemy.

Gap to Perfection

★ Worth pulling109.8% solo106.5% in team

This Potential gives generic stat boosts, and its Critical Rate bonus is especially valuable given Rossi's Critical DMG buffs and her Seething Blood Talent.

In gameAgility +20, Critical Rate +7%.

Legendary Destination

★ Worth pulling125% solo116.6% in team

A higher Ultimate multiplier plus an extra Critical DMG bonus suits Rossi especially well, adding pure damage with no gameplay changes but still ranking among her best direct gains since so much of her damage comes from Ultimate.

In gameUltimate "Razorclaw" Ambuscade improved: DMG Multiplier is increased to 1.1 times of the original; Critical DMG Dealt is increased by +30%.

Every Potential Rossi has, in full, is on the Kit tab. This is only which of them are worth the pulls.
