Best Rosaria Build: Weapons, Artifacts & Teams (v7.0)

REVERSE MELTFREEZEBUFF SUPPORT

REVERSE MELT Build

Weapons

1

Staff of the Scarlet Sands

CRIT Rate

CRIT Rate substat plus an Elemental Mastery to ATK conversion, so Melt's EM scaling and raw hit damage rise together.

2

Crimson Moon's Semblance

CRIT Rate

Enormous CRIT DMG substat with a self-buff that keeps running through off-field downtime, so no shield or setup is required.

3

Staff of Homa

CRIT DMG

HP to ATK conversion with a low-HP damage bump; the CRIT DMG substat alone makes it a safe stat stick at any investment.

4

Lumidouce Elegy

CRIT Rate

CRIT Rate plus a stacking damage bonus, patching the stat you are least likely to have on artifacts.

5

Primordial Jade Winged-Spear

CRIT Rate

Begins at CRIT Rate and stacks ATK and damage while on-field, rewarding a slightly longer field window.

6

Calamity Queller

ATK%

ATK substat with a damage bonus that climbs each second on-field — spend a beat longer before swapping out.

7

Vortex Vanquisher

ATK%

ATK substat and stacking ATK while shielded; bring a shielder to keep the doubled bonus live.

8

Deathmatch

CRIT Rate

Cheapest CRIT Rate fix on the list — full value against two or more enemies, and still fine in single target.

9

Missive WindspearR5

ATK%

ATK substat and a free damage buff after any reaction: more ATK and Elemental Mastery, refreshed by Melt itself.

10

Engulfing Lightning

Energy Recharge

Energy Recharge converting into ATK; take it when the Burst will not return without an ER sands.

11

Dragon's Bane

Elemental Mastery

Elemental Mastery substat and +20% damage against Pyro-affected targets — Melt uptime keeps the passive permanently active.

12

Wavebreaker's Fin

ATK%

ATK substat with Burst damage scaling off the team's total energy cost, ideal in high-cost double Pyro comps.

13

Skyward Spine

Energy Recharge

Energy Recharge and a CRIT Rate buff on Normal Attacks; purely an energy-comfort pick when Burst uptime is the bottleneck.

14

"The Catch"

Energy Recharge

Free and rotation-perfect: Burst DMG and Burst CRIT Rate for a kit whose damage lives in the Burst.

Artifacts

1

Gilded Dreams

4

4pc turns off-element teammates into Elemental Mastery and same-element ones into ATK, so a Pyro partner still feeds Melt-relevant stats.

2

Emblem of Severed Fate

4

Energy Recharge converts into Burst damage, so an ER weapon or sands pays for itself — the default when the Burst is the entire rotation.

3

Noblesse Oblige

4

2pc Cryo DMG lifts both Skill and Burst. Skip the 4pc — its Freeze-dependent CRIT Rate never holds in a Melt team.

CRIT RateCRIT DMG

Cast Skill before Burst: the CRIT Rate from Ascension 1 Talent also counts toward Ascension 4 Talent Bonus.
Rosaria's Skill and Burst can trigger Reverse Melt (1.5x) with another Pyro applier for quick, powerful damage.

REVERSE MELT
Rosaria's ICD-free Skill and Burst let every proc Melt; snapshotting buffs on Burst makes this her top personal damage build.

Weapons
Calamity Queller: fully stacked passive; passive not doubled.
Primordial Jade Winged-Spear: averaged 3 stacks.
Vortex Vanquisher: shielded; unshielded slightly better than Deathmatch [R1].
Deathmatch: [R4-R5] with 2+ enemies just below Calamity Queller; with Gilded Dreams (4) can beat all 4✩ options and even Primordial Jade Winged-Spear in single target.
Dragon's Bane: [R4-R5] slightly better than Calamity Queller.
Wavebreaker's Fin: [R4-R5] just below Calamity Queller.

Artifacts
Emblem of Severed Fate (4): at 130%+ Energy Recharge needs can surpass Gilded Dreams (4).

FREEZE
Works for quickswap/sub-DPS or perma-freeze DPS; usually secondary DPS to on-field freeze carries like Ayaka, Ganyu, Wriothesley.

Weapons: 120% Energy Recharge requirement; some weapons need 0 CRIT Rate rolls.
Calamity Queller: assumed max stacks; passive not doubled.
Wavebreaker's Fin: [R4-R5] with 270 energy cost team just below Staff of Homa.
Vortex Vanquisher: assumed 2 stacks; unshielded.
Primordial Jade Winged-Spear: assumed 2 stacks.

Artifacts
Noblesse Oblige (4): only quickswap/support, not perma-freeze DPS; consider only if no decent Blizzard Strayer (4) and no teammate holds it.

SUPPORT
Focuses on buffing, energy generation, and Cryo application; personal damage still matters but is lower priority.

Weapons
Favonius Lance: best when team energy needs are unmet; otherwise use a CRIT Rate weapon to benefit A4 buff.

Artifacts
Instructor (4): better for teams valuing Elemental Mastery over ATK, like Hu Tao VapeMelt, but sacrifices CRIT Rate buffing.
Archaic Petra (4): only if she can reliably pick up Crystallize shards.
Scroll of the Hero of Cinder City (4): unconditional 12% DMG to any element she reacts with; (2) also helps Energy Recharge requirement when a Night Soul Burst triggers in party.
