Genshin Impact 5★ Hydro Catalyst Main DPS
Everlasting Moonglow is the closest fit on the game's own numbers: Sangonomiya Kokomi's kit multiplies HP, and a weapon is ranked here on whether its ascension stat and its passive act on that stat. Nocturne's Curtain Call, Ring of Yaxche and Jadefall's Splendor come next. No playtested ranking has been imported for Sangonomiya Kokomi, so this is arithmetic over the kit data rather than a damage measurement.
Run Heart of Depth on Sangonomiya Kokomi, with Nymph's Dream and Tenacity of the Millelith behind it. Main stats are HP% sands, Hydro DMG Bonus goblet, CRIT Rate / CRIT DMG circlet. Roll substats in the order CRIT Rate > CRIT DMG > HP% > Energy Recharge.
Talent priority is Normal Attack > Elemental Skill > Elemental Burst. The Elemental Burst costs 70 energy, which is what an Energy Recharge target has to clear.
The strongest team is Sangonomiya Kokomi, Nahida, Raiden Shogun and Kaedehara Kazuha, built around Sangonomiya Kokomi: Dendro · Hyperbloom.
Sangonomiya Kokomi's abilities multiply HP. That is read from the scaling rows on the Elemental Skill and Burst, not from the ability description, so it reflects what the game actually multiplies rather than what the text mentions.
Everlasting Moonglow is the closest fit on the data: it is a 5-star catalyst with HP as its ascension stat, and its passive acts on HP. Ring of Yaxche is the best 4-star alternative.
Heart of Depth. Its 2-piece bonus is: Hydro DMG Bonus +15% Its 4-piece bonus is: After using Elemental Skill, increases Normal Attack and Charged Attack DMG by 30% for 15s.
