Genshin Impact 4★ Hydro Catalyst Healer
Everlasting Moonglow is the closest fit on the game's own numbers: Barbara's kit multiplies HP, and a weapon is ranked here on whether its ascension stat and its passive act on that stat. Jadefall's Splendor, Ash-Graven Drinking Horn and Nocturne's Curtain Call come next. No playtested ranking has been imported for Barbara, so this is arithmetic over the kit data rather than a damage measurement.
Run Heart of Depth on Barbara, with Nymph's Dream and Vourukasha's Glow behind it. Main stats are HP% sands, HP% goblet, Healing Bonus circlet. Roll substats in the order Energy Recharge > HP% > CRIT Rate > CRIT DMG.
Talent priority is Elemental Burst > Elemental Skill > Normal Attack. The Elemental Burst costs 80 energy, which is what an Energy Recharge target has to clear.
The strongest team is Barbara, Nilou, Collei and Dendro Traveler, built around Barbara: Hydro · Bloom.
Barbara'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. Ash-Graven Drinking Horn 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.
