When I first pulled Rosaria, I was struck by how her Cryo polearm attacks sliced through enemies like shards of moonlight. Her critical hit-focused gameplay demanded a team that amplified her strengths through elemental reactions and strategic rotations. Over months of testing, I’ve discovered seven characters that transform her from a lone nun into the icy heart of devastating team compositions. Let me break down why these synergies work so well.
7. Fischl: The Electro Queen
Fischl’s Oz becomes Rosaria’s best friend. When I deploy the raven and switch to Rosaria, the battlefield turns into a Superconduct factory. The constant Electro application from Oz (with just 1-second downtime!) shreds physical resistance, making Rosaria’s spear strikes hit like a blizzard. Plus, Fischl’s A4 passive triggers additional Electro damage whenever reactions occur – perfect for our Cryo crit machine.
6. Beidou: The Counter-Storm
For tougher content where survival matters, I slot in Beidou. Her Tidecaller counterattack feels like conducting lightning – block an enemy’s strike, then watch Rosaria’s Cryo explosions dance with purple arcs. The 15% damage reduction and interrupt resistance from Beidou’s burst make Rosaria’s close-range attacks safer. It’s like having an electrified safety net.
5. Chongyun: Cryo Resonance Engine
When I need constant Freeze reactions, Chongyun’s frost field becomes essential. His skill converts normal attacks to Cryo damage within its radius, turning even non-Cryo teammates into ice machines. Combined with Rosaria’s crit rate boost, this creates a 55% crit rate paradise. I once froze a Lawachurl mid-leap using this combo – it shattered beautifully.
4. Xingqiu: The Rainmaker
Xingqiu’s rain swords work overtime in my Rosaria teams. The Hydro application persists through character swaps, enabling permanent Freeze status when paired with Rosaria’s burst. I’ve watched entire Hilichurl camps become ice sculptures while his damage reduction keeps everyone alive. His healing at higher constellations feels like divine intervention.
3. Diona: Icy Sustain
Diona’s my go-to when facing corrosion or needing stamina for charged attacks. Her shielding and healing combine with Cryo resonance for ultimate comfort. The movement speed boost from her shield makes Rosaria’s hit-and-run playstyle fluid. Plus, her EM boost at C6 turns Melt comps into nuclear options.
2. Xiangling: Pyro Powerhouse
For Melt reactions, I unleash Xiangling’s Pyronado. Timing Rosaria’s burst during Guoba’s pepper breath creates a swirling vortex of melting health bars. The best part? Xiangling’s energy needs are perfectly offset by Rosaria’s particle generation. It’s like they were designed to fuel each other’s elemental fury.
1. Barbara: Freeze Enabler
Early-game players sleep on Barbara, but her constant Hydro application via Melody Loop enables budget Freeze teams. I’ve trapped entire Ruin Guard groups in permafrost using her skill with Rosaria’s ice storms. Her revive at C6 saved my 12-3 Spiral Abyss run more times than I’d care to admit.
FAQ
Q: What artifact set works best for support Rosaria?
A: I swear by 4-piece Noblesse Oblige for burst support, but Blizzard Strayer turns her into a Freeze comp monster.
Q: Which weapon should I prioritize?
A: Deathmatch for crit rate synergy, but Dragonspine Spear’s physical damage boost works wonders in Superconduct teams.
Q: Can Rosaria main DPS without constellations?
A: Absolutely! Her C1-2 enhance damage, but proper team building makes her viable at C0.
Q: Best alternative if I don’t have Fischl?
A: Lisa surprisingly works well – her DEF shred from A4 passive complements Rosaria’s crit focus.
Q: How much crit rate is optimal?
A: I aim for 70-80% before Cryo resonance – her passive converts excess crit rate into team-wide buffs.
Through endless domain runs and Abyss resets, I’ve learned that Rosaria thrives in teams that value precision over brute force. Whether you’re freezing the world or melting faces, her versatility shines when paired with these seven champions. The Sister of Sin becomes a Saint of Destruction in the right hands – now go pierce the heavens with icicles!
