Should you pull?
YES if you're building a Water Code team. Her Hero-Level stacking buff for the whole team (up to +12.76% strong-element damage and +10.01% ATK at Level 11) is a rare design that snowballs the longer the fight runs. Without enough Water Code allies, or if you prioritize turn-one kills, her value drops noticeably.

Skill Investment Priority
Suggested path: 1/1/1 (playable) → 4/1/7 → 7/4/10 → 10/7/10. Prioritize Skill 1 since it's the Water team-wide buff that scales with Hero Level and drives long-term power; Skill 2 only helps EXP gain, so it can lag behind.
Strengths & Weaknesses
Strengths
- Grows stronger the longer she fights thanks to the Hero Level mechanic, and her buff spreads to the whole Water Code team, not just herself.
- Burst III both buffs damage and deals Hero-scaled DoT — double value in one turn.
Weaknesses
- Weak early on since Hero Level needs EXP to build up, unsuited to opening one-shot kills.
- Her team buff only benefits Water Code allies, so mixed-element teams can't use it fully.

General Info
Recommended Teams
Campaign
- Water Code team: Guillotine: Winter Slayer · 1 CDR (Liter) · 1 Water tank · 2 flex Water attackers. The more Water Code allies you field, the further her Hero-Level-scaled buff spreads effectively.
Arena/PvP
- Extended-fight team: Guillotine: Winter Slayer · Blanc · 1 tank · 2 flex slots. Since her power ramps up with Hero Level, she suits longer matches better than turn-one kills.
Raid & Interception
- Sustained DoT team: Guillotine: Winter Slayer · Novel · 1 healer · 2 flex Water attackers. Her Burst deals continuous Hero-scaled damage to the highest-HP enemy, good for long boss attrition fights.
