Genshin Impact’s Rosaria is a sister of the Church of Favonius – though she may not look it – in Mondstadt and a four-star cryo polearm wielder. Her elemental burst gives her the power to deal a mighty slash, doling out huge cryo damage and summoning a deadly ice lance that deals continuous cryo damage to any nearby – and incredibly unlucky – enemies.

Let’s spy on what makes Genshin Impact Rosaria the best she can be.
What’s the best Genshin Impact Rosaria build?
| Best weapon | Staff of Homa |
| Weapon substitutes | Wavebreaker’s Fin, Crescent Pike |
| Best artifact set | Blizzard Strayer |
| Main stats | -Sands – Energy recharge -Goblet – Cryo damage bonus -Circlet – Crit rate/damage |
| Sub stats | Attack, crit rate, crit damage |
Rosaria is a four-star cryo polearm wielder who applies consistent off-field cryo damage, has a short skill cooldown, and boasts great team flexibility. Her kit offers a very rare crit buff, regenerates a decent amount of particles, and both her skill and burst synergize well with melt team comps.
Unfortunately, Rosaria does face some stiff competition when it comes to other cryo units. Her burst is also quite restrictive in its field of impact, as the AoE is fairly small. Rosaria is an affordable, versatile, and powerful unit and you shouldn’t overlook her – she is capable of filling many roles, and with our help, you should have no regrets about investing in this icy beauty.
How do I use Rosaria?
The best part of Rosaria’s kit is her crit-boosting passive, which comes into play when her elemental burst is active. Therefore, as soon as it’s ready, deploy it and swap to your DPS to deal an extra hefty bit of damage.
What are the best Genshin Impact weapons for Rosaria?
Like many characters, Rosaria’s best weapon depends heavily on how you intend to use her. In a melt team, the five-star Staff of Homa is the best option for Rosaria, as it still maintains the second-best slot in freeze teams due to its amazing offensive capabilities. However, it’s a highly contested weapon and may be better on another character given its status.
Wavebreaker’s Fin at R5 is the best option for freeze and the second best option for melt. Even when you aren’t using its passive, it still offers a higher attack boost than all other options. Even at lower refinement ranks, it is still your best option if you don’t have a spare Staff of Homa at hand (and, honestly, who does?).
| Weapon | Effect | How to obtain |
| Staff of Homa (five-star) | Bonus effect: Crit damage Skill: Increases HP by 20%. Rosaria receives an attack bonus based on 0.8% of her max HP. When HP drops below 50%, the attack bonus increases by an additional 1% of Rosaria’s max HP |

Weapon banner (alongside Xiao) |
| Wavebreaker’s Fin (four-star) | Bonus effect: Attack Skill: Increases elemental bust damage by 0.12% for every point of the entire party’s combined maximum energy capacity. You can achieve a total of 40% elemental burst damage in this way |

| Crescent Pike (four-star) | Bonus effect: Physical damage Skill: After you pick up an elemental particle, normal and charged attacks deal an extra 20% damage for five seconds |

What are the best artifacts for Rosaria?
Generally, a full four-piece set of Blizzard Strayer is the best set for most team comps, with Noblesse Oblige coming close behind. However, if you’re looking for a unique reverse melt build, you can go with Lavawalker instead. The Emblem of Severed Fate artifact set would also work wonders for Rosaria in elemental damage-focused builds.
| Artifact set | Effect | How to obtain |
| Blizzard Strayer | Two equipped: Cryo damage bonus Four equipped: Increases crit rate by 20% when attacking an enemy affected by cryo. If the enemy freezes, it increases crit rate by an additional 20% |

Momiji Dyed Court domain |
| Pale Flame | Two equipped: Increase physical damage Four equipped: When an elemental skill hits opponents, Rosaria’s attack increases by 9% for seven seconds. This can stack two times and can trigger every 0.3 seconds. If two stacks are reached, the two-piece effect increases by 100%. |
