Rossi
SSendgame dps
sub_dpsdpssupport
Rossi earns SS tier because of her rare ability to convert Arts Inflictions into Vulnerable, amplifying both Physical and Heat damage for the entire team. She also carries strong personal burst and crit buffs, making her a flexible sub-DPS who can anchor hybrid compositions once her setup requirements are met.
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.
Insights
Core Mechanics
- Arts Inflictions are converted into Vulnerable stacks by Combo Skill Sequence 2, and a perfect QTE adds another stack.
- Battle Skill's Wolven Ambrage applies Razor Clawmark, a DoT that also raises Physical and Heat damage taken.
- Ultimate applies Heat Infliction, letting Rossi supply her own combo requirement and deal a high burst of Heat damage.
- Seething Blood creates extra Heat hits and heals when skills crit a Razor Clawmarked enemy.
Scaling
- Rossi scales primarily with Agility and Intellect; critical rate lets her take full advantage of Combo Skill and Ultimate crit damage boosts.
- Her damage contribution becomes much stronger once she can reliably chain Vulnerability and Arts Infliction, so team synergy is critical.
- Late-game builds stack critical rate and Agility to maximize both her personal burst and her debuff uptime.
Team Role
Rossi slots into hybrid or double-carry teams as a sub-DPS and enabler rather than a pure main DPS. She needs allies who can apply Arts Inflictions, or she needs to manage her Ultimate so it provides the Heat Infliction herself. Once her setup is satisfied, she debuffs enemies with Razor Clawmark and Vulnerability, increasing the Physical and Heat damage of the entire team. In practice, teams often build around protecting and enabling Rossi as if she were the hypercarry, because her debuffs and burst output create a large damage payoff.

Explanation
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.
Notes
- 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.
