Tier S
- Furina
- Neuvillette
- Yelan
- Xingqiu
- Kokomi
These characters rank Tier S as they offer unmatched consistency in Hydro application for enabling transformative Vaporize, Freeze, or Bloom reactions, along with their diverse roles as powerful on-field DPS options, exceptional off-field damage and Hydro support, and potent healers enhancing team survivability.
Tier A
- Nilou
- Tartaglia
These characters rank in Tier A due to their potent Hydro damage output and ability to enable strong elemental reactions, but they may have limitations such as specific team composition requirements or less consistent Hydro application compared to S-tier characters.
Tier B
- Ayato
- Mona
- Barbara
These characters rank in Tier B due to their respectable Hydro application and utility, but may have limitations such as Ayato's burst requiring specific setups for optimal damage, Mona's reliance on her burst for significant Hydro application, or Barbara's focus on healing over consistent Hydro application compared to higher-tier Hydro characters.
Tier C
- Candace
Candace rank in Tier C because her Hydro application and overall support capabilities are limited compared to higher-tier Hydro characters, and her niche focus on buffing Normal Attacks further restricts her utility.
