Rossi arrived in Arknights: Endfield as a six-star Sword-wielding Guard in Version 1.1. Her listed element is Physical, but her abilities deal both Physical and Heat damage, which makes the team around her especially important. She needs Arts Infliction and Vulnerability on the same enemy to activate her Combo Skill, then uses the resulting Critical bonuses to prepare a powerful Ultimate. If you are deciding whether to build her, start with the teammates and equipment you already own rather than assuming her signature weapon is required.
Rossi Character Background
Rossina “Rossi” Wulfperl Luppino is the young leader of the Wolf Clan in Valley 4. Her role requires her to protect a group living with limited resources, even when that means presenting a harder side of herself to outsiders. That contrast between responsibility and affection also shapes her relationship with the Endministrator. In combat, her direct approach is paired with a more technical system of marks, status effects, and timed follow-up attacks.
Rossi Character Positioning
Rarity: 6-star. Class: Guard. Weapon: Sword. Element: Physical. Combat role: Physical/Heat damage dealer and Vulnerability enabler.
Rossi is not simply a Physical attacker with a Heat-colored Ultimate. Her Basic Attack and much of her Combo Skill deal Physical damage, while the follow-up from Crimson Shadow, her Ultimate, and the extra hits from Seething Blood deal Heat damage. This split matters when deciding which teammates should provide damage buffs or consume Vulnerability. A Physical-focused ally can help her ordinary attacks, but a buff that affects only Physical damage will not improve her Heat Ultimate.
Her central requirement is an enemy carrying both Vulnerability and Arts Infliction. The Combo Skill consumes Arts Infliction and provides a short Critical buff, while her Battle Skill can follow up against a Vulnerable enemy and apply Razor Clawmark. From there, the aim is to use ally buffs and Rossi's Ultimate before the Combo Skill's buff expires. Teams without steady Arts Infliction may struggle to repeat this sequence even if Rossi's personal gear is strong.
Talents and Skills
Rossi's skills work best when their conditions are met in the right order. The damage of her Combo Skill changes with the Arts Infliction stacks it consumes, and her Battle Skill gains an important follow-up only when Vulnerability is already present. Fixed multipliers taken from a fully upgraded skill should not be treated as damage that every Rossi build will produce, regardless of skill rank, enemy resistance, or buffs.
Combat Talents
Nicks and Scratches — Razor Clawmark
When the Wolven Ambrage follow-up from her Battle Skill hits, Rossi applies Razor Clawmark. At the talent's higher rank, the mark lasts 25 seconds, deals Physical damage each second based on 30% of her ATK, and makes its target take 12% more Physical and Heat damage. At the lower rank, the duration and bonuses are smaller. These are talent effects, not measured increases to total team DPS; the result depends on which attacks your team uses while the mark is active.
The key practical detail is the trigger condition. Pressing Crimson Shadow against an enemy with no Vulnerability does not automatically give you the mark. First apply Vulnerability, then land the Wolven Ambrage follow-up. Once the mark is active, both Rossi's damage types and the matching attacks from her allies can benefit, so refresh it when needed rather than spending SP merely to recast it early.
Seething Blood — Extra Heat Hit and Recovery
When one of Rossi's skills scores a Critical hit against an enemy carrying Razor Clawmark, Seething Blood triggers an additional Heat hit and restores HP based on her Intellect. At the higher talent rank, the extra hit uses a 24% ATK multiplier; both the damage and healing are multiplied by 1.5 if the target is also Combusted. This makes Critical Rate useful beyond ordinary critical damage, but the recovery is conditional and should not replace a team's entire defensive plan.
Critical Rate is especially relevant because her Combo Skill supplies a temporary Critical Rate increase. That does not make every weapon or piece of gear with a Critical stat equally valuable: a build with reliable Combo Skill uptime needs to consider that buff, while a team that rarely triggers the Combo Skill cannot count on it. Consistency matters more than treating the highest possible damage screenshot as a normal rotation.
Combat Skills
Basic Attack — Seething Wolfblood
Rossi performs a sequence of Physical attacks, with a Finisher available against Staggered enemies. The Finisher deals heavier Physical damage and recovers SP. Ordinary attacks also have an equipment role: with Lupine Scarlet, Critical hits from her skills and attack sequence help build the weapon's Wolven Blood stacks. If you use her signature weapon, allow enough hits to build the passive before committing to a major damage window.
Battle Skill — Crimson Shadow
Crimson Shadow costs 100 SP, deals Physical damage, and applies Lift. If the enemy already has Vulnerability, Rossi also performs Wolven Ambrage, a Heat follow-up that enables Razor Clawmark through Nicks and Scratches. This makes the order of your skills important. In SP-limited fights, arranging Vulnerability before using Crimson Shadow helps secure the follow-up rather than spending a full Battle Skill on its weaker first part alone.
Combo Skill — Moment of Blazing Shadow
The Combo Skill becomes available when an enemy has both Vulnerability and Arts Infliction. It has two sequences: the second consumes the Arts Infliction stacks, deals Physical damage that scales with the number of stacks consumed, and buffs Rossi's Critical Rate and Critical DMG for 15 seconds. At skill Rank 12, those buffs reach 25% Critical Rate and 50% Critical DMG; lower skill ranks provide smaller bonuses. Perfect timing on the second sequence adds another Vulnerability stack.
There is an easy mistake to avoid here: if another attack consumes the Arts Infliction between the two Combo Skill sequences, Rossi loses the status needed for the second sequence's Vulnerability generation. Make sure the necessary stacks are still on the target and finish the second input at the correct timing. Since the Critical buff lasts only 15 seconds, prepare your other effects before the Combo Skill whenever the encounter allows it.
Ultimate — “Razorclaw” Ambuscade
Rossi's Ultimate costs 110 Ultimate Energy and deals multiple Heat hits, ending with a slash that applies Heat Infliction. Its many hits can also activate Seething Blood when the target is marked and the attacks critically hit. Try to align the Ultimate with the Combo Skill's Critical buff and Razor Clawmark, then use the resulting Heat Infliction to set up the next reaction. The exact timing depends on how fast the team can generate Energy, how much SP it spends, and whether the battle starts with a charged Ultimate.
Weapons and Gear
Weapon choice needs a consistent investment baseline. A Potential 0 signature and a Potential 5 Battle Pass weapon require different resources, so they should not be described as an equal-cost comparison. Without a fixed character build, enemy, rotation, and repeatable damage record, an exact weapon-efficiency percentage would be misleading. The comparison below uses verified weapon effects instead of an unsupported DPS ratio.
Signature Weapon — Lupine Scarlet (6-star Sword)
At weapon Level 90, Lupine Scarlet has 505 Base ATK. With its Agility and Critical Rate stat lines tuned to Rank 9, it grants 156 Agility and 19.5% Critical Rate. Its separate Fracture: Gnashing Wolves passive is not automatically Rank 9 just because those two stat lines are maxed. At passive Rank 4, it grants 25.6% ATK and builds Wolven Blood when the wielder's skill deals Critical damage; at passive Rank 9, the ATK bonus is 44.8%. Those values describe two different tuning levels and must not be presented as one default weapon build.
At passive Rank 4, each Wolven Blood stack grants 1.6% Physical and Heat DMG Dealt, up to 16 stacks. Reaching 16 stacks grants an additional 38.4% to those damage categories for 20 seconds, after which the stacks are removed. The weapon can therefore support both halves of Rossi's kit, but its strongest window needs enough Critical hits beforehand. In short encounters with little setup time, or when the stacks expire just before her Ultimate, the effective gain will be smaller than the full passive description suggests.
Alternative Weapon — Glorious Memory (Battle Pass Sword)
Glorious Memory is an option if you already have access to the Battle Pass weapon and do not want to obtain Rossi's signature. At Level 90, it has 490 Base ATK; at Rank 9 on its Agility and Critical Rate stat lines, it also provides 156 Agility and 19.5% Critical Rate. Its passive rewards applying Vulnerability, granting a bonus to the next Ultimate used within the stated duration, up to three stacks. That bonus applies to the Ultimate rather than to Rossi's Basic Attacks, Combo Skill, and other damage in the rotation.
A Potential 0 Glorious Memory and a Potential 5 copy should be treated separately. The higher-Potential version requires more copies and strengthens the weapon; it is not a free upgrade implied by owning one Battle Pass reward. Glorious Memory is especially relevant when your team prepares Vulnerability and finishes a short fight with an Ultimate, while Lupine Scarlet is better suited to a longer sequence in which Rossi can build and use its Critical-hit stacks. The relative damage depends on both the encounter and the rest of the build.
The following table is a tooltip calculation, not a damage-efficiency test. It uses Level 90 weapons at Potential 0, with the two stat lines at Rank 9 and the separate passive at Rank 4. Because no fixed Rossi Potential, skill levels, gear rolls, team buffs, target defense, or full rotation has been established for a controlled comparison, it deliberately does not claim that one weapon deals a particular percentage of the other's total damage.
| Weapon | Investment in this calculation | Reproducible passive calculation | What the number applies to |
|---|---|---|---|
| Lupine Scarlet | Lv.90, P0; stat lines Rank 9, passive Rank 4 | 16 × 1.6% = 25.6% from Wolven Blood stacks, plus 38.4% at full stacks | Physical and Heat DMG Dealt during the full-stack window; not a 64% total DPS increase |
| Glorious Memory | Lv.90, P0; stat lines Rank 9, passive Rank 4 | Up to 3 × 19.2% = 57.6% from its Ultimate-related passive stacks | Applicable Ultimate damage only; not a 57.6% increase to total rotation DPS |
These bonuses cannot be compared by subtracting one row from the other. Lupine Scarlet covers Physical and Heat damage across multiple skills but needs time to reach 16 stacks; Glorious Memory focuses its stacked bonus on the Ultimate. A valid numerical weapon comparison would need the same Rossi level, Potential, talent ranks, gear and Artifice rolls, teammates and their equipment, enemy defenses and resistances, starting SP and Ultimate Energy, Critical-hit assumptions, and a fixed rotation length. It would also need a calculation sheet or repeatable damage logs. No such in-house test is claimed here, so the guide does not assign an unsupported percentage to either weapon.
Recommended Gear — MI Security
MI Security fits Rossi because Critical Rate helps her trigger Seething Blood and build Lupine Scarlet's stacks. The set also provides offensive bonuses when its Critical-hit conditions are met. A practical setup uses MI Security pieces centered on Agility and Intellect; the specific off-piece can change if it improves her stat balance or Ultimate Energy generation. If your current gear already lets her land reliable critical hits and complete a full burst cycle, replacing it solely to match a recommended item name may be a poor use of resources.
Do not judge a gear change from a weapon ranking alone. Additional Critical Rate has less value once temporary buffs push the effective rate too high, while more Ultimate Gain Efficiency is useful only if it lets you reach a meaningful Energy breakpoint. When deciding between a better Critical piece and an Energy-focused piece, check whether your Ultimate is actually ready when Rossi's Combo Skill and ally buffs line up.
Team Building
Rossi needs at least one reliable Arts Infliction source, but the remaining slots can support either her Physical damage, her Heat burst, or the team's SP economy. Gilberta is a useful partner because she can help provide the required statuses and amplify damage, though she is not the only way to build a functional team. The main decision is whether the party wants to consume Vulnerability with Physical effects or preserve the setup for Rossi's Heat-focused Ultimate.
Example team: Rossi + Gilberta + Endministrator + Wulfgard. Gilberta contributes Arts Infliction and damage amplification, Wulfgard provides Heat-related setup and access to Combustion, and the Endministrator can use Vulnerability for additional Physical damage. This lineup has several competing SP demands, so using every skill as soon as it becomes available is not a reliable plan. If the Endministrator's setup makes the rotation too expensive, Da Pan can fill a Vulnerability-consuming role with a different SP profile.
Perlica can replace one of the enabling slots when you need accessible Electric Infliction and reaction setup. Ardelia offers another form of damage support, but her own trigger conditions must be checked against Rossi's status sequence. Wulfgard and Perlica are not interchangeable in every rotation: Combustion improves Seething Blood's conditional effect, while Electric-related reactions and buffs affect a different part of the team. A roster without Gilberta can still run Rossi by pairing a source of Arts Infliction with operators that maintain Vulnerability and manageable SP use.
Practical rotation — Rossi, Gilberta, Endministrator, Wulfgard
- Prepare Vulnerability and Arts Infliction on the same target using the team's available skills. Avoid using a reaction that consumes the required Arts Infliction before Rossi's second Combo Skill sequence.
- Trigger Moment of Blazing Shadow and complete its second sequence with Perfect Timing. This consumes the Arts Infliction, adds Vulnerability when the condition is met, and starts Rossi's 15-second Critical buff.
- Use Crimson Shadow against the already Vulnerable target. Its Wolven Ambrage follow-up applies Razor Clawmark, which prepares both Rossi's extra Critical-triggered hits and the target's Physical/Heat damage-taken debuff.
- Apply Combustion and the teammates' remaining buffs if their skills are ready. Consume Vulnerability with the Endministrator only if doing so fits the team's planned Physical damage and does not disrupt a required trigger.
- Use Rossi's Ultimate while the Critical buff and Razor Clawmark are active. If she does not yet have 110 Ultimate Energy, repeat the status and Combo/Battle Skill sequence, recover SP where possible, and burst on the next prepared window rather than treating a full-Energy opener as guaranteed.
This is a priority order for the listed team, not a frame-perfect script or a tested damage log. Exact button order changes with operator Potentials, whether Wulfgard can refresh a trigger, starting Energy, enemy status resistance, and your available SP. With Lupine Scarlet, give Rossi time to build Critical-hit stacks before her biggest hit when the fight allows it. With Glorious Memory, check that Vulnerability applications have built the Ultimate-related passive before using the burst. The purpose of the rotation is to explain the conditions you must satisfy, not to promise a fixed clear time.
Pull Advice
Consider Rossi if your account has reliable Arts Infliction and wants a damage dealer who can contribute both Physical and Heat damage. Gilberta is helpful, but the wider question is whether the team can establish Vulnerability, trigger her two-part Combo Skill, and support a 110-Energy Ultimate without running out of SP. Accounts with Wulfgard, Perlica, or a Physical Vulnerability consumer have several directions to explore, although the exact rotation will differ. If you like active timing decisions and already own suitable support operators, she can fit without requiring every premium weapon or Potential upgrade.
Consider delaying the pull if you already have a well-built damage dealer for the same encounters or would need to build several new supports at once. Rossi's mixed damage is an advantage only when the team can support both the status sequence and the burst window; it does not make every Physical-only or Heat-only support equally useful. The resource cost of raising a new operator, weapon, skills, and gear should be weighed against improving your current team. Her signature weapon can be an upgrade, but its stack requirements and acquisition cost make it a separate decision from obtaining Rossi herself.
Conclusion
Rossi is a Physical Guard whose best damage windows combine Arts Infliction, Vulnerability, Razor Clawmark, Critical hits, and a Heat Ultimate. The important upgrade path is to make that sequence reliable: secure a usable Arts Infliction source, keep her Combo Skill timing consistent, then improve her Critical stats and Energy timing. Lupine Scarlet rewards extended Critical-hit setup, while Glorious Memory directs more of its value toward the Ultimate and has different costs at P0 and P5.
A weapon-performance percentage has meaning only alongside the character build, enemy, team, rotation, and calculation or test record that produced it. The weapon effects and tuning assumptions here can be checked directly, while a universal DPS ratio would hide too many differences between accounts. If you already have a functional weapon and MI Security gear, build the team and rotation first; only then decide whether the cost of another weapon is justified.
