Mondstadt’s pop idol, Barbara, is a 4-star playable character in Genshin Impact. She owns a Hydro vision, and her primary role is support.
Barbara is one of the easy picks to include in a party because she is easy to build and her talents or skill kit is simple. This nun from the Church of Favonius uses a catalyst, and with the stat she needs to focus on, there are not many choices available in-game. Her healing scales off her maximum HP, so the higher her HP is, the more heal she can provide to the entire party.
As of this writing, there are three catalyst weapons with HP as a secondary stat, and these weapons all vary in rarity.
Thrilling Tales of Dragon Slayers
This weapon is a 3-star and perhaps the easiest to obtain. Although it can only be obtained from wish banners, being a 3-star gives it a higher drop rate than the other weapons in this list.
Despite giving the lowest HP bonus, some players prefer this 3-star catalyst over the other two due to its passive effect.
This catalyst gives at least a 24% increase in ATK to the new character taking the field when switching characters. However, this effect can only be triggered in solo play or in a co-op party where you control two characters with Barbara as one of them.
Prototype Amber
The 4-star catalyst Prototype Amber is a healer-designed weapon with its passive effect that regenerates all party members’ HP for some time after the wielder of this weapon uses an elemental burst.
This effect will boost Barbara’s healing capabilities and is very helpful when her elemental burst is not enough to recover a character’s HP fully. During this HP recovery period, the wielder of this weapon will also regenerate a certain amount of energy at a fixed interval.
At level 90, Prototype Amber also gives a bonus of 41.3% HP, which is higher than the bonus provided by the Thrilling Tales of Dragon Slayers.
Everlasting Moonglow
The Everlasting Moonglow is an event-exclusive 5-star weapon, which means it can only be obtained by wishes on a weapon banner where it is featured.
This catalyst gives a maximum HP bonus of 49.6% at level 90. This is the highest HP bonus among the three weapons on this list.
Although it is designed as the best in slot (BIS) weapon for Sangonmiya Kokomi, this catalyst fits well with Barbara, especially if you want a slight increase in damage when playing in coop mode.
Since it is a 5-star weapon, the Everlasting Moonglow has a high base ATK up to 608. Its passive effect increases the healing bonus of the weapon wielder and increases their normal attack damage by a percentage of their maximum HP.
Conclusion
Based on the weapons features above, the Everlasting Moonglow is the best weapon for Barbara to maximize her healing capabilities. That is if you have the Primogems to wish for it and if you are lucky enough to get it.
The best F2P choice is the Prototype Amber since you can craft it. You can purchase at least one billet from the jewelry and souvenir shops in Mondstadt and Liyue and use it for crafting this catalyst.
If you have Barbara’s summer wear fashion, especially if you participated in the Golden Apple Archipelago event, this look matches perfectly with the Everlasting Moonglow.
