Hey Travelers! With power creep in Genshin, C2s are now crucial for big upgrades. Here's the top-value C2s in Version 6.4 "Luna V" (March 2026) – massive power spikes worth saving Primogems for! (Older ones like Raiden & Nahida C2 have fallen off, not included.)
Furina
C2 provides near 100% uptime on Burst DMG Bonus for the whole team — even Geo and Physical teams get huge value. Fits almost every composition except certain Lunar setups. Full Fanfare stacks heal while boosting summon damage (summons also scale with Burst). Top-tier sub-DPS output.

Citlali
C2 grants Hydro/Pyro allies -40% RES shred, +250 EM, Thrilling Tales-style ATK buff, +40% DMG Bonus, +45% ATK, and stronger shields. Melt Pyro DPS sees especially ridiculous gains (50%+ total damage increase).
Mavuika
Main DPS build: Massive personal damage boost + 20% enemy DEF shred. ~50% overall damage increase from C0 to C2 — big numbers feel amazing.
Off-field Pyro support: Extra utility & team buffing value, better long-term
Skirk.
Burst playstyle: +10 extra schemes, each Burst segment +328.5% multiplier → ~+1971% total across six hits.
On-field: +70% ATK during Skill — crucial for Cryo/Hydro teams.
Overall ~50% power spike from C0 to C2.
Columbina
Core Lunar reaction support. C2 massively speeds up Gravity stacks + boosts her sub-DPS.
Full Radiance (e.g. 40k HP): Lunar Electro-Charged +400 ATK, Lunar Bloom +140 EM, Lunar Crystallize +400 DEF.
Major breakpoint for all three Lunar playstyles.
Zibai
Aggressive numerical scaling like Mavuika/Skirk. C2 massively buffs second hit of special Skill — ~700k per hit with full support.
C0 → C2 delivers close to 80% damage increase — one of the highest value jumps.
