Charlotte vs Diona

Front-loaded team heals vs. the defensive Cryo shield

TL;DR — Quick Pick

Pick Charlotte if…

  • In Furina teams where team-wide healing is mandatory
  • When you need a Cryo TTDS holder for your carry
  • To keep a permanent mark of Cryo on widespread enemies

Pick Diona if…

  • When you need a shield to prevent being interrupted or killed
  • As a reliable battery for Cryo units like Eula or Ayaka
  • In Melt teams where her C6 200 EM buff is game-changing
Verdict

Diona is the more versatile defensive unit due to her shield and battery capabilities. Charlotte's only major advantage is her massive team-wide heal, which makes her a specialized pick for Furina teams.

AyakaAyaka

With Charlotte

Charlotte serves as a vital healer and Cryo applicator for Ayaka in Freeze teams that lack a Hydro healer like Kokomi. Her Burst provides instant team-wide healing to counter HP drain mechanics while maintaining Cryo resonance for a 15% CRIT Rate bonus. This allows Ayaka to focus entirely on her Burst damage while Charlotte keeps the enemies frozen and the team healthy.

With Diona

Diona acts as a versatile battery and shielder for Ayaka, generating Cryo particles with her 'Icy Paws' to help fuel Ayaka's expensive 80-cost Burst. Her shield provides necessary interruption resistance and a movement speed buff, making Ayaka's dashes and rotations smoother. This pairing provides Ayaka with the safety and energy she needs to maintain her offensive pressure.
