珊瑚宮心海

Thrilling Tales of Dragon Slayers:
In most teams Kokomi functions as a healer and an off field hydro applier, Thrilling Tales of Dragon slayers having a HP% substat as well as a massive atk% buff for a team member makes it the ideal weapon of choice for Kokomi as a support. Additionally it's HP% substat allows her to still deal competent damage if the team requires it

Hakushin Ring:
The Energy Recharge substat helps with Kokomi's energy requirements allowing you to easily maintain 100% uptime on her elemental skill. Additionally its passive buffs multiple teammates at once, making it an especially powerful option for taser teams.
Prototype Amber, Everlasting Moonglow:
Should you find yourself playing a team that requires Kokomi to contribute significantly to team damage then these weapons may be useful. Everlasting Moonglow being her signature weapon has a HP% substat, as well as a passive that helps with her on field damage and energy needs. Prototype Amber does the same but to a much smaller extent due to it's lower stats as a 4* weapon
