New Content
| Nahida | Adds more options to Rosaria’s teams. Nahida introduced some potential for new Reverse Melt comps and some Fridge teams. |
Playstyles
Reverse Melt
Rosaria having high multipliers on both her Burst and Skill, no Internal Cooldown on both of them and being able to snapshot buffs onto her Burst make her an excellent option for the Reverse Melt team archetype, both as an off-field damage dealer or a quickswap one.
Freeze
Rosaria’s Freeze teams make full use of her high and consistent off-field damage potential and superb Energy generation alongside multiple CRIT Rate sources — classic to a Freeze team — to create a comfortable and smooth playstyle against enemies Frozen in place.
Support
While having high Talent multipliers and the potential to make good use of external buffs, Rosaria support capabilities including excellent Energy generation, consistent Cryo application, CRIT Rate share and Phys RES Shred make her an exceptional choice for various teams outside of her main ones.

Character Overview
Talent Priority
>
>>
Normal Attack Levels are not consequential for all team archetypes listed.
Talents
Normal Attack: Spear of the Church
Description
Normal Attack
Performs up to five consecutive spear strikes.
Charged Attack
Consumes a certain amount of Stamina to lunge forward, dealing damage to opponents along the way.
Plunging Attack
Plunges from mid-air to strike the ground below, damaging opponents along the path and dealing AoE DMG upon impact.
Rosaria’s Normals don’t contribute anything meaningful to her teams.
Elemental Skill: Ravaging Confession
Description
Rosaria swiftly shifts her position to appear behind her opponent, then stabs and slashes them with her polearm, dealing Cryo DMG.
This ability cannot be used to travel behind opponents of a larger build.
Getting a back CRIT hit using Rosaria’s Skill gives her 12 CRIT Rate which also boosts her Ascension 4 CRIT Rate buff. It has a 6s cooldown with good Energy generation, making it ideal in quickswap teams where she can quickly swap in to cast it.
Elemental Burst: Rites of Termination
Description
Rosaria’s unique take on this prayer ritual: First, she swings her weapon to slash surrounding opponents; then, she summons a frigid Ice Lance that strikes the ground. Both actions deal Cryo DMG.
While active, the Ice Lance periodically releases a blast of cold air, dealing Cryo DMG to surrounding opponents.
Rosaria’s Burst is the most important part of her kit, providing CRIT Rate after cast with her Ascension 4 Passive. Starts out with 2 initial damage instances and 4 Damage-over-Time procs (up to 6 with Constellation 2). Rites of Termination is the core component of Rosaria’s kit as it can reliably trigger reactions for each of its damage procs with its high multipliers, snapshot buffs and enable CRIT Rate share for her teammates.
Ascension 1 Passive: Regina Probationum
Description
When Rosaria strikes an opponent from behind using Ravaging Confession, Rosaria’s CRIT Rate increases by 12% for 5s.
Getting a CRIT hit behind an enemy with Rosaria’s Skill gives her 12% CRIT Rate.
Ascension 4 Passive: Shadow Samaritan
Description
Casting Rites of Termination increases CRIT Rate of all nearby party members (except Rosaria herself) by 15% of Rosaria’s CRIT Rate for 10s.
CRIT Rate Bonus gained this way cannot exceed 15%.
After casting Rosaria’s Burst, the whole party except Rosaria herself gains 15% of her CRIT Rate for 10s. This Passive stacks with her Ascension 1 Passive as well so it is recommended to use Rosaria’s Skill before her Burst.
Exploration Passive: Night Walk
Description
At night (18:00 – 6:00), increases the Movement SPD of your own party members by 10%.
Does not take effect in Domains, Trounce Domains, or Spiral Abyss. Not stackable with Passive Talents that provide the same effects.
Constellations
Constellation 1: Unholy Revelation
When Rosaria deals a CRIT Hit, her ATK SPD increases by 10% and her Normal Attack DMG increases by 10% for 4s.
Increases Normal Attack damage and Movement Speed by 10% after CRIT hit. Not a helpful Constellation as Rosaria’s Normals don’t contribute much to her teams’ damage.
Constellation 2: Land Without Promise
The duration of the Ice Lance created by Rites of Termination is increased by 4s.
Increases Rosaria’s Burst duration by 4 seconds which gives her 2 extra DoTs procs. Her most important Constellation.
Constellation 3: The Wages of Sin
Increases the level of Ravaging Confession by 3.
Increases Skill Level by 3. Good Constellation, just nothing game-changing.
Constellation 4: Painful Grace
Raviging Confession’s CRIT Hits regenerate 5 Energy for Rosaria. Can only be triggered once each time Ravaging Confession is cast.
Critting on Rosaria’s Skill gives her 5 Flat Energy, reduces her Energy Recharge requirements depending on how many Skill casts she can get in a rotation.
Constellation 5: Last Rites
Increases the level of Rites of Termination by 3.
Increases Burst Level by 3. Very helpful Constellation as most of Rosaria’s damage comes from her Burst.
Constellation 6: Divine Retribution
Rites of Termination’s attack decreases opponents’ Physical RES by 20% for 10s.
Dealing damage with Rosaria’s Burst reduces enemies’ Physical Resistance by 20% for 10s, only useful in Physical teams.

Artifacts
ER Requirements
| Per Rotation | No C4 | With C4 | |
| Solo Cryo | 1 Skill | >240% (not recommended) | |
| 2 Skills | 200% | 180% | |
| 3 Skills | 155% | 120% | |
| Double Cryo | 1 Skill | 190% | 170% |
| 2 Skills | 145% | 120% | |
| 3 Skills | 125% | 100% | |
It is recommended to run at least 1 Favonius weapon in Solo Cryo teams. For best results from Rosaria at higher ER requirements, equipping 4p EoSF and a weapon with secondary ER stat with an offensive passive is highly suggested.
One Favonius weapon passive proc per rotation lowers Rosaria’s requirements by 15-20% ER.
3 Skills per rotation extends some rotations and/or is difficult to execute overall.
Use ERC for accurate ER requirements for your teams.
Artifact Stats
 Sands |  Goblet |  Circlet |
| EM/ATK% | Cryo DMG Bonus | CRIT Rate/DMG |
Substats: ER% > CRIT Rate > CRIT DMG > EM > ATK%
Building more CRIT Rate is important in order to increase Rosaria’s Ascension 4 CRIT Rate buff and to ensure an Ascension 1 and Constellation 4 proc. EM Sands can be better if used with an ATK% weapon while ATK% Sands can be better if used with an EM weapon. Use Genshin Optimizer for the most accurate results.
Artifact Sets
| Artifact Set | Description |
| 4 Gilded Dreams | The 2pc and 4pc increase of EM and ATK% make it Rosaria’s best set for Reverse Melt at lower ER requirements. |
| 4 Lavawalker | The set grants 35% DMG Bonus from the 4 pc, making it a very competitive option if obtained from farming for CWoF. |
| 4 Emblem of Severed Fate | Good generalist set for Burst reliant characters, may out damage other sets at higher Energy requirements. |
| 2 EM/ATK%/DMG% combinations | The main selling point of 2pc/2pc sets is that they can be obtained as a byproduct of farming other sets, which make them relatively competitive with 4pc sets. |
Weapons
| Weapon | Description |
| Staff of the Scarlet Sands | The weapon’s high amounts of CRIT Rate and EM conversion to ATK make it the best choice for Reverse Melt Rosaria, who benefits from all 3 stats. |
| Staff of Homa | Homa has a high CRIT DMG substat along with an ATK-boosting passive, which makes it easy to focus on building other offensive stats. |
| Deathmatch | Has the highest CRIT Rate for a 4-star spear, which helps boost her CRIT Rate share from her A4. Locked behind Battle Pass. |
| Wavebreaker’s Fin | Wavebreaker’s Fin provides Burst DMG% and ATK%, which when paired with its high base ATK, makes it a very competitive option. Scales very well with refinements, even beating some 5-star options at R5. |
| Dragon’s Bane | Having EM as a substat and a DMG% passive make it an excellent choice for Reverse Melt. |
| Missive Windspear | Generally worse than other options, still a solid choice if you obtained it from the past event. |
| “The Catch” | “The Catch’s” passive makes it seem like it’s a very good weapon for Reverse Melt, but it is held back by the excess amount of ER from its substat. It may prove to be better than other options at higher ER requirements. |
Teams
Team-Building
- Needs a character to apply Pyro/Burning to enable Melt.
- Recommended to run another Cryo character to reduce Energy Recharge requirements.
Notable Teammates
| 2nd Slot: Bennett | |
| Not a necessary addition in theory; but Bennett provides everything Rosaria needs such as Pyro application/Absorption for an Anemo unit, large Flat ATK buff, synergy with other Pyro characters and healing. | |
| 3rd Slot: Aura Provider | |
| Pyro Flex: Xiangling, Klee, Yanfei | Responsible for applying Pyro aura in addition to dealing damage and/or buffing the team. |
| Anemo Flex: Kazuha, Jean | Both Kazuha and Jean have special interactions with Bennett, which makes it very easy for them to apply Pyro using their bursts. They can also carry 4 piece Viridescent Venerer to further increase the team’s damage. |
| Dendro Flex: Nahida | Nahida’s Dendro application has introduced new possibilities with Burning in Melt teams. Ideally, with off-field Nahida as the 3rd slot, the last slot should be an Anemo character, who can absorb Pyro and group enemies like Kazuha to resupply Burning aura and ensure Melt triggers from Rosaria over continuous rotations. Results are still being studied. |
| 4th Slot: Support/Battery | |
| Cryo Flex: Shenhe, Kaeya, Ganyu, Chongyun | Can be any of the following, buffer, battery, or a unit who can make use of the Melt nature of the team. |
| Anemo Flex: Kazuha, Sucrose, Heizou | All these Anemo characters can buff both the Pyro applicator and Rosaria in 1 way or another, which makes them a viable option as the 4th slot. |
Example Teams
This is not a comprehensive list of teams, and the inclusion of a certain team or lack thereof does not necessarily indicate the power level of the team in question. This list is not ranked.
4-star-only team that has Bennett as the healer and support, Xiangling to apply Pyro aura while doing damage and Rosaria and Kaeya to Melt off of the Pyro applied by Xiangling.
Reverse Melt team to maximize Rosaria’s own damage using Bennett, Kazuha and Shenhe.
Freeze
Artifacts
ER Requirements
| Situation | No C4 | With C4 |
| 1 Skill | 195% | 175% |
| 2 Skills | 150% | 125% |
One Favonius weapon passive proc per rotation lowers Rosaria’s requirements by 15-20% ER.
Venti in the team and absorbing Cryo lowers them by 20-25% ER.
3 Skills per rotation is generally not advised as it unnecessarily prolongs some rotations and/or is simply difficult to execute overall.
Use ERC for accurate ER requirements for your teams.
Artifact Stats
Sands | Goblet | Circlet |
| ATK%/ER | Cryo DMG Bonus | CRIT Rate/DMG |
Substats: ER% > CRIT DMG > CRIT Rate > ATK%
As with all Burst focused units, meeting ER requirements is the most important thing. If Rosaria is using Blizz then she should not get above 45% CRIT Rate because of all the added CRIT Rate from Blizzard and Cryo Resonance. If Rosaria is using 4pc Noblesse/Emblem then the substat priority changes to CRIT Rate instead of CRIT DMG to maximize her CRIT share.
Artifact Sets
| Artifact Set | Description |
| 4 Blizzard Strayer | Best set for Freeze teams, providing 15% Cryo DMG Bonus and 40% CRIT Rate. Recommended to run CRIT DMG Circlet alongside this full set. |
| 4 Noblesse Oblige | Viable 2nd option if there is no available 2nd 4 BS set. |
| 4 Emblem of Severed Fate | If the team has an existing 4 NO holder and there is no 2nd 4 BS set. |
Weapons
| Weapon | Description |
| Staff of Homa | Staff of Homa is an extremely good weapon for all DPS characters, but especially so in Freeze because it offers CRIT DMG and ATK, which are the most needed stats in Freeze teams. |
| Wavebreaker’s Fin | Wavebreaker’s Fin provides Burst DMG% and ATK%, which when paired with its high base ATK, makes it a very competitive option. Scales very well with refinements. |
| Other ATK% Weapons (Calamity Queller, Vortex Vanquisher, Lithic Spear) | The abundance of CRIT Rate from 4pc Blizzard Strayer and Cryo Resonance makes ATK much more valuable compared to teams that have external ATK buffers such as Sara or Bennett. |
| Favonius Lance | Exchanges Rosaria’s personal damage for more battery potential. May be better than other options in Energy-hungry teams. |
| Blackliff Pole | Only 4-star that has CRIT DMG substat, which makes it a good choice for Freeze if available. The stacking mechanic is unreliable and dependent on the enemies being faced. Not recommended to spend Starglitter on it. |
| “The Catch” | The de facto F2P spear. The ER substat along with the Burst DMG% and CRIT Rate passive make it a solid choice for Freeze teams. |
Teams
Team-Building
- Double Cryo reduces ER requirements and gives access to Cryo Resonance.
- Reliable Hydro application for Freeze uptime.
- Flex slot is generally an Anemo unit for crowd control and 4p Viridescent Venerer.
Notable Teammates
| Character | Description |
| Cryo Flex: Ayaka, Ganyu, Kaeya, Chongyun, Diona, Shenhe | Usually an on-field Cryo DPS that can benefit from Rosaria’s off-field presence. Extends to supportive roles if other slots do not provide any. |
| Hydro Flex: Kokomi, Mona, Xingqiu, Yelan, Ayato, Tartaglia | Hydro appliers that provide consistent aura with additional damage, healing and/or buffs. |
| Anemo Flex: Kazuha, Venti, Sucrose, Jean, Sayu, Heizou | Have access to crowd control and 4p Viridescent Venerer to reduce enemy resistance. |
Example Teams
This is not a comprehensive list of teams, and the inclusion of a certain team or lack thereof does not necessarily indicate the power level of the team in question. This list is not ranked.
Relatively F2P Freeze team that has a focus on 4 star units. Anemo options other than Kazuha are viable too.
Makes use of Venti’s tight grouping and Ganyu’s Quadratic scaling damage to dish out AoE damage in a 15 second rotation.
General Support
Artifacts
ER Requirements
Heavily relies on Rosaria’s teammates. Use ERC for accurate ER requirements for your teams.
Artifact Stats
Sands | Goblet | Circlet |
| ER/ATK% | Cryo DMG Bonus | CRIT Rate/DMG |
Substats: ER% > CRIT Rate > CRIT DMG > ATK%
ER% Sands should only be used if ER% requirements can not be met with ATK% Sands.
Artifact Sets
| Artifact Set | Description |
| 4 Noblesse Oblige | Grants Burst DMG% for Rosaria from the 2pc and 20% ATK for the whole team including Rosaria herself. |
| 4 Emblem of Severed Fate | Best option if there is another character holding 4pc Noblesse. |
| 2 ER/ATK%/DMG% combinations | Can be used if there isn’t a ready Emblem set for Rosaria. |
Weapons
| Weapon | Description |
| Favonius Lance | Despite not boasting the best personal damage, it is the only polearm that can directly help the team with its passive. |
| Deathmatch | Has the highest CRIT Rate for a 4-star spear, which helps boost her CRIT Rate share from her A4. Locked behind Battle Pass. |
| Primordial Jade Winged-Spear | Jade Spear has higher personal damage but less CRIT Rate compared to Deathmatch. |
| Engulfing Lightning | Engulfing has the highest ER substat in the game and gives more ER with its passive in addition to introducing ER to ATK conversion. However, Rosaria’s ER requirements aren’t high enough to warrant this weapon most of the time. |
| “The Catch” | Rosaria’s Energy requirements may be relatively high in certain teams, which justifies the usage of “The Catch”. |
Teams
Team-Building
- Rosaria has excellent Energy generation and can be brought in as a battery for Cryo characters in addition to other elements.
- Has excellent off-field damage and Cryo application.
- A4 increases teammates’ CRIT Rate.
- C6 provides Physical RES Shred for Physical DPS units.
Notable Teammates
| Character | Description |
| Eula | As Eula needs a Cryo battery, Rosaria is an excellent option due to having high particle generation, CRIT Rate share and Phys RES Shred at C6. Additionally, Rosaria’s strong application can sustain Cryo aura by herself and as a result, maintain a fair amount of Cryo Resonance uptime overall. |
| Itto | A good flex slot if Albedo or Zhongli is not available, provides buffs, off-field damage and Cryo application for Crystallize shields if needed. |
| Razor | Rosaria is an excellent unit in Physical Razor teams, since she can proc Superconduct, shred Physical RES and buff Razor with her CRIT Rate share. |
| Hu Tao | Double Cryo Hu Tao teams give Hu Tao the chance to Melt some of her attacks. Rosaria can be paired with other units such as Kaeya or Diona for Cryo Resonance, extra Cryo aura and additional utilities. |
| Other on-field DPS units | Listed above are just some examples of teams Rosaria can fit into. There are plenty of other teams aside from what is already mentioned where Rosaria plays a supportive position. |
Example Teams
This is not a comprehensive list of teams, and the inclusion of a certain team or lack thereof does not necessarily indicate the power level of the team in question. This list is not ranked.
Rosaria’s Constellation 6 is one of the few accessible sources of Phys Shred that last for the entirety of Eula’s field time. Rosaria can use 2 skills per Rotation, which will reduce Eula’s energy requirements even further. Due note that Rosaria’s CRIT Rate buff may not last till the finishing hit of Eula’s Burst.
Rosaria has CRIT Rate share after casting her Burst and excellent off-field Cryo application that helps in generating Crystallize shields. This makes her an excellent flex slot for Itto teams if Zhongli is not available.
Due to the nature of Razor’s long field time requirements, he wants an off-field Cryo character that can apply Cryo for Superconduct. Rosaria fulfills that condition in addition to boosting CRIT Rate and shredding Physical RES at C6.
The mix of 2 off-field Cryo applicators enables Hu Tao to Melt some of her attacks. However, this does not mean that every Charged ATK will Melt.
Physical
While Rosaria has Constellations and Talents that suggest her functions as a Physical DPS such as her Constellation 1 and 6, it is in fact not the case. Even when Rosaria is built as a Physical DPS, more than 30% of her damage comes from her Burst and Skill, which is why we won’t be going over Physical builds in this guide.
This is not to dissuade anyone from building Physical Rosaria, however. If you wish to do so then feel free by all means.
