Investment & usage
Treasure: She has a dedicated Treasure, ranked at medium priority on the recent community raising sheet. Final target stage for Collection Item / Treasure: stage 3.
Investment profile: A character whose skill build-up and Overload priority are laid out on the community raising sheet (updated 2026.7). Use cases: PvE / PvP, (Electric Solo Raid only).
Skill priority: Skill 2 = Burst Skill > Skill 1
Overload priority: Elemental Damage > Max Ammo (useful extra options: ATK, Crit Damage, Crit Rate)
Recommended cubes: Relic Bear, Tactical Bear, Relic Tempering. Use cases: PvE / PvP, (Electric Solo Raid only). [Added 2026-08-04] This priority rating is disputed: Eppenbaum marked her down hard, saying that her restrictive trigger condition of "Electric bosses only" makes her effectively useless in PvE, and that "unless you have already raised Rosanna, upgrading the Treasure is not recommended". There is no cross-check from the other three YouTubers, so this is a single-source claim and confidence is low — needs re-checking against real usage data.

Showing 6 representative teams.
Double T2 V2 - Better but Niche
BossRosanna· Crown· Anis: Sparkling Summer· Maiden: Ice Rose· Little Mermaid
[Source: prydwen.gg Team Database] Higher damage variant in cases of equal investment and boss with core. Substitutions: Crown may be replaced with Nayuta or Bunny Ade. (Element: Electric)
3RL Nuke
PvPRei Ayanami· Mari Makinami Illustrious· Rosanna· Centi· Jackal
[Source: prydwen.gg character page] Mari is used as a simple damage buffer for nukes. Scarlet or Rei can be replaced by any fast nuker DPS. Red Hood is used as a B1 unit to buff both Mari's and the nuker's AoE. The special assist from Mari comes when she uses her Burst Skill!
Rosy's Revenge
PvPScarlet· Mast: Romantic Maid· Rosanna· Centi· Jackal
[Source: prydwen.gg character page] This comp is 3 RL, but Rosanna will be buffed with Mast's Crit Rate and ATK, which makes it easier to confirm kills with Burst. A variation of Scarlet - Anne: Miracle Fairy - Rosanna comp without healing/reviving.
Banish the SGs
PvPDrake· Anne: Miracle Fairy· Rosanna· Soda: Twinkling Bunny· Mihara: Bonding Chain
[Source: prydwen.gg character page] An Attacking team focused around shutting down SG teams (although Makima does that better). In this team, Mihara: Bonding Chain is sacrificed to fill up Burst Gen instantly with Rosanna, starting up the burst chain. Soda: Twinkling Bunny can be replaced with Noir. Counterable by opposing Rosanna (who also benefits from Mihara: Bonding Chain's death). Anne: Miracle Fairy for reviving (ideally Mihara: Bonding Chain to abuse stronger DoT from personal damage buffs) or Blanc for stalling. Substitutions: Soda: Twinkling Bunny can be replaced by Noir, Anne: Miracle Fairy can be replaced by Blanc.
One-Night-Stand Makima
PvPDrake· Soda: Twinkling Bunny· Rosanna· Makima· Mihara: Bonding Chain
[Source: prydwen.gg character page] Similarly, this team is a little more developed for Makima havers, focusing on sacrificing Mihara: Bonding Chain and letting Makima stall for 7s as Mihara: Bonding Chain's DoT cripples the enemy one by one. Also potentially strong against glass-cannon wipers. Biscuit can be added for extra stalling, but she must stay alive (and Makima must be attacked). Mihara: Bonding Chain is investment and dupe dependent. Substitutions: Add Biscuit if more stall needed over Soda or Drake.
Rise from the Dead (Adaptive Speed)
PvPMihara: Bonding Chain· Blanc· Mana· Rosanna· Helm
[Source: prydwen.gg character page] The same team as "Rise from the Dead" but with adaptive speed. This team is around 3.5 RL to 4 RL depending on Charge Speed, but it can speed up to around 2 RL to 2.5 RL and even around 1.5 RL with a bug that we cannot currently explain (ref: https://youtu.be/PUWebkRXrMM). This is thanks to Rosanna's Burst Gen Instant Fill from deaths of enemy or allied units. In this case, since we want Mihara: Bonding Chain to die anyway (she's going to be useless if she doesn't die before Full Burst), we can just pair Rosanna with her. With Rosanna, this team can go faster/slower depending on how fast the enemy kills Mihara: Bonding Chain. There is no too fast (well, unlikely)! Substitutions: Mana can be replaced with Rapunzel, although Mana is better.
