Rosaria is a nun who skips prayers to hunt down threats to Mondstadt. She is a highly aggressive Cryo Sub-DPS whose primary utility lies in her ability to share 15% of her Crit Rate with the party and (at C6) shred Physical Resistance, making her indispensable for Eula and Melt teams.
Pros
- Shares Crit Rate with teammates (up to 15%).
- Strong off-field Cryo application (no circle impact like Diona).
- Excellent particle generation (Short Skill CD).
- C6 shreds Physical RES, making her Eula's best support.
- Teleports behind small enemies (gap closer).
Cons
- Burst is stationary (enemies can move out of it).
- Cannot teleport behind large enemies/bosses.
- Needs high Crit Rate investment to maximize buff.
- Burst duration (8s) is shorter than Kaeya's without C2.
Quick Guide (TL;DR)
If you don't have time for the math, here is the cheat sheet.
- Best Artifact: 4pc Noblesse Oblige (Support) or 4pc Emblem (Personal DMG).
- Alt Artifact: 4pc Blizzard Strayer (Freeze only) or 4pc Lavawalker (Reverse Melt).
- Best Weapon: Favonius Lance (Team Battery - Most Recommended).
- Damage Weapon: Staff of the Scarlet Sands (Stat Stick) or The Catch.
- F2P Weapon: The Catch (R5) or Dragon's Bane (Reverse Melt).
- Main Stats: SANDS: ATK% or ER | GOBLET: Cryo DMG | CIRCLET: CRIT Rate.
- Talent Priority: Elemental Burst > Elemental Skill > Normal Attack (Ignore).
- Top Team: Rosaria + Eula + Raiden + Zhongli (Physical).
Pro Tip: Always use Skill before Burst. Her A1 Passive grants her 12% Crit Rate if she hits an enemy from behind with her Skill. This 12% is included in the Crit Rate she shares with her team via her Burst (A4 Passive).

Talent Breakdown & Mechanics
Elemental Skill: Ravaging Confession
- The Backstab: Rosaria shifts behind the enemy and pierces them. Note: She cannot teleport behind large enemies (Ruin Guards, Lawachurls).
- Crit Buff (Passive): Hitting an enemy from behind increases her Crit Rate by 12% for 5s. This is crucial for her burst snapshot.
- Particle Gen: Creates 3 particles. Excellent battery for Ayaka/Eula.
Elemental Burst: Rites of Termination
- Cost: 60 Energy | Cooldown: 15s | Duration: 8s (12s at C2)
- The Field: Slams an Ice Lance into the ground that pulses Cryo DMG every 2s.
- Crit Sharing (Passive): Upon casting, increases Crit Rate of all nearby party members (except herself) by 15% of Rosaria's Crit Rate for 10s. Max bonus is 15% (requires 100% CR on Rosaria).
- No ICD: Every pulse applies Cryo, making it perfect for Reverse Melt (Rosaria melts) or enabling Pyro carries.
Passive: Shadow Samaritan
- The Core: Casting Rites of Termination increases Crit Rate of all nearby party members (except Rosaria) by 15% of Rosaria's Crit Rate for 10s. This counts buffs she has on herself (like the 12% from Skill).
Talent Priority Order:
- Elemental Burst (Level 9) - Main damage and utility source.
- Elemental Skill (Level 8) - Energy and decent damage.
- Normal Attack (Level 1) - Ignore unless Physical Main DPS.
Stat Requirements & ER Thresholds
Your goal is 100% Crit Rate to maximize the team buff, but don't sacrifice ER.
| Team Context | Build | ER Requirement |
|---|---|---|
| Freeze (Double Cryo) | Noblesse/Blizzard | 140% - 160% |
| Reverse Melt | Emblem/Lavawalker | 160% - 180% |
| Eula Support | Noblesse (Favonius) | 150% - 170% |
Substat Priority:
- CRIT Rate (Priority #1 for support role)
- Energy Recharge (Until requirement met)
- ATK% (For personal damage)
- CRIT DMG (Secondary priority)
Best Artifacts Comparison
| Set Name | Role | Reasoning |
|---|---|---|
| 4pc Noblesse Oblige | BiS Support | Buffs team ATK by 20%. Since Rosaria bursts often, this has high uptime. Essential for Eula/Ayaka teams. |
| 4pc Emblem of Severed Fate | Sub-DPS | Best for personal damage, especially in Melt teams where she needs higher ER. |
| 4pc Blizzard Strayer | Freeze | Good for personal damage in Freeze, BUT the Crit Rate gained from this set DOES NOT count towards her A4 sharing passive. Only base stats count. |
Weapon Rankings
| Weapon | Type | Performance | Notes |
|---|---|---|---|
| Favonius Lance | ER% | S+ (Support) | High Base ATK for a 4-star. Generates particles for the team on Crit. Since you build Crit Rate anyway, this weapon is perfect. |
| The Catch (R5) | ER% | S (Damage) | Best F2P option for personal damage. The 12% Crit Rate from passive counts towards her personal stats (but not sharing). |
| Deathmatch | CRIT Rate | S (Stat Stick) | BP Weapon. Massive Crit Rate stat (36.8%). Easiest way to reach 100% Crit Rate for max buff sharing. |
| Dragon's Bane | EM | A (Melt) | Only use for Reverse Melt teams where Rosaria is the one triggering reactions. |
Constellation Value
Rosaria is a complete unit at C0, but C2 and C6 are significant milestones.
- C2: Land Without Promise - (Core) Increases Ice Lance duration by 4s (Total 12s). This significantly increases total damage and Cryo application uptime. Essential for Freeze/Physical support.
- C5: Last Rites - (Damage) +3 Levels to Burst. Good for Melt nukes.
- C6: Divine Retribution - (Physical Support) Burst hits decrease enemy Physical RES by 20% for 10s. This makes her the best offensive support for Eula/Razor.
Verdict: C2 is the most important for general use. C6 is key for Physical teams.
Top Team Compositions
1. Eula Physical Support
- Main DPS: Eula
- Battery/Buffer: Rosaria (C6)
- Electro: Raiden Shogun / Fischl
- Sustain: Zhongli / Bennett / Mika
Why it works: Rosaria batteries Eula (Favonius), buffs her Crit Rate (making Eula's nuke more consistent), and shreds Physical RES (C6). Perfect synergy.
2. Reverse Melt Quickswap
- Melter 1: Rosaria
- Melter 2: Kaeya / Chongyun
- Pyro App: Xiangling
- Buffer: Bennett
Why it works: Rosaria's burst has no ICD, meaning every tick can melt if enough Pyro is applied. This team deals massive AoE damage.
Rotations & Combos
Crit buff Rotation:Rosaria Skill (Backstab for +12% CR) > Rosaria Burst (Share CR) > Swap to DPS
Tip: Always try to position yourself so that using Skill teleports you behind the enemy. If you are already behind them, just cast it. Large bosses cannot be backstabbed, so you lose the 12% bonus (and thus share less).
Frequently Asked Questions
Does Blizzard Strayer Crit Rate count for sharing?
No. Only Crit Rate visible on the stat sheet counts. Conditional buffs like Blizzard Strayer or Cryo Resonance do not transfer.
Rosaria vs. Kaeya?
Rosaria is better for crit sharing and stationary fights. Kaeya is better for mobile fights (burst moves with you) and generates slightly more energy. They are often used together.
