Rossi Skill Kit & Playstyle Analysis

Rossi is a 6-star Operator of the Guard class and Physical attribute. She uses a sword as her main weapon type and is a very interesting Physical and Heat Hybrid DPS character.

Arknights: Endfield Rossi
Basic Attack: An attack with up to 5 sequences that deals Physical DMG. As the controlled operator, Final Strike also deals 18 Stagger.
Dive Attack:  Basic attack performed in mid-air becomes a dive attack that deals Physical DMG to nearby enemies.
Finisher: Basic attack performed near a Staggered enemy becomes a finisher attack that deals massive Physical DMG and recovers some SP.
Basic AttackLeveling Priority: Low
Reason: Rossi’s normal attacks are rarely used as she doesn’t want to be the main on field operator, so players do not need to level this up unless you want to maximize her damage output.
Charges to the target to deal Physical DMG and apply Lift. If the target already has Vulnerability stack(s), the skill also unleashes a Wolven Ambrage that charges at the target to deal Heat DMG.
Battle SkillLeveling Priority: High
Reason: Rossi’s main damaging move, so players should level this up as much as possible.
When an enemy has both Vulnerability and Arts Infliction stacks. Rossi’s combo skill has 2 consecutive sequences. COMBO SEQUENCE 1 deals Physical DMG to the target. 
COMBO SEQUENCE 2 consumes all Arts Infliction stacks from the target, deals Physical DMG based on the number of Arts Infliction stacks consumed, applies 1 instance of Lift, and buffs Rossi’s Critical Rate and Critical DMG Dealt at the same time. If COMBO SEQUENCE 2 is cast with perfect timing, it applies 1 more stack of Vulnerability.
Combo SkillLeveling Priority: High
Reason: A good portion of Rossi’s damage comes from her combo skill, so players should level this up as high as possible.
Rossi flutters her cape and unleashes a flurry of stabs that quickly deals multiple sequences of Heat DMG to the target. She then performs a two-sequence slash attack with her dagger that deals massive Heat DMG and applies Heat Infliction
UltimateLeveling Priority: High
Reason: Another of Rossi’s important main modes of damage output and should be leveled up as much as possible as soon as possible.
Battle skill improved: After Wolven Ambrage deals DMG, Rossi applies Razor Clawmark to the target for 15s. This effect cannot stack.
For the duration of Razor Clawmark, the target takes 25% ATK (Rossi’s) of Physical DMG per second and suffers Physical DMG Taken and Heat DMG Taken +6%.
Talent 1Unlock Priority: High
Reason: An amazing talent that further boosts Rossi’s overall damage output and her support effect to the team.
When Rossi’s skill deals Critical DMG to a Razor Clawmarked enemy, trigger another hit that deals 24% ATK (Rossi’s) of Heat DMG and restores [Intellect × 0.08] HP to Rossi. If the target is also Combusted, then the aforementioned DMG and HP Restoration effects are increased to 1.5 times.
Talent 2Unlock Priority: High
Reason: Another amazing talent for Rossi that allows her to deal additional damage and sustain herself with special healing effects.

Unlike most other operators whose abilities and skill kit is designed to support and deal damage in 1 single element, Rossi is the first Operator whose skill kit is divided into 2 different elements, with her Battle Skill and Combo Skill being Physical Damage, while her Ultimate deals Heat Elemental damage. She is a very unique character that bridges the gap between 2 different teams, allowing different elemental Operators to work together.

Rossi’s Battle Skill allows her to inflict Vulnerabilility on enemies while dealing Physical damage to them, helping to facilitate different Physical team’s playstyle. When the enemy is inflicted with both an elemental infliction and vulnerability, Rossi can use her Combo Skill to deal damage to enemies, inflicting an additional stack of Vulnerability onto them. When using her Combo skill, if players time her Combo skill correctly, she will deal an additional instance of damage and inflict additional Vulnerability stacks on enemies.

When using her Ultimate, Rossi will deal Heat damage to enemies within her range, dealing additional damage based on her critical stats. This ability makes her a viable candidate for a Heat Sub DPS character in a Heat team. With how her hybrid skill kit works, Rossi can work as both a Physical team’s sub DPS character or a main DPS character for a special hybrid Heat team.
