AsGenshin Impact’s first-ever Four-Star Cryo catalyst user, Charlotte is a reporter from Fontaine who works at The Steambird. Since Charlotte constantly travels to get the latest scoop, she wields her trusty camera in combat to deal Cryo damage and take frozen snapshots of her enemies.
On top of her damage, Charlotte’s Elemental Burst creates a small area that constantly heals the HP of your entire team while applying cryo and dealing small increments of damage. As a catalyst user, Charlotte certainly has a massive catalog of weapons she can use, so check out the list below to see which weapon benefits your playstyle the most.

7Thrilling Tales Of Dragon Slayers - Three-Star
While Thrilling Tales of Dragon Slayers is only a Three-Star weapon and is certainly more useful onHP scaling healers such as Kokomi,you’re able to still utilize this catalyst’s impressive and downright overpowered effect in certain scenarios. Whenever you switch to another character after using this catalyst, the following character will receive a 48 percent boost to their attack stat for ten seconds.
Keep in mind that this weapon does not affect Charlotte’s damage or healing, but instead helps certain freeze teams that do not have a buffing unit like Bennett. Since Bennett applies such a massive attack buff to your team, using this catalyst can help your Cryo DPS characters deal significantly more damage.

6Favonius Codex - Four-Star
If you are struggling to activate your elemental burst on Charlotte or any of your other characters, then Favonius Codex is a fantastic catalyst that provides energy for your entire team. This weapon gives you a 45.9 percent increase in your Energy Recharge and a 60 to 100 percent chance of generating three energy particles when you land a critical hit.
While this does require you to build enough Crit Rate to reliably activate this weapon’s passive ability, you can also quickly swap in between characters to funnel your energy. Essentially, you can generate the particles while playing Charlotte, then quickly swap off to another character that does not have energy for their elemental burst.

5Flowing Purity - Four-Star
While Flowing Purity is certainly easy to obtain, as it is crafted by the blacksmith in Fontaine, the weapon’s passive can be somewhat tricky to complete with Charlotte as the sole healer on your team. Specifically, while using this catalyst, whenever you activate your Elemental Skill, a Bond of Life forms, calculated from a percentage of your character’s own HP.
This immediately gives your active character a 16 percent Elemental Damage increase, and if you successfully heal the Bond of Life and clear the debuff, then you will also receive an extra Elemental Damage buff based on the HP of the Bond of Life. While all of these bonuses are certainly useful for dealing extra damage, Charlotte’s only healing ability is her Elemental Burst, so you will want enough Energy Recharge to always cast this ability.

4Oathsworn Eye - Four-Star
The Oathsworn Eye is a catalyst that synergizes perfectly with Charlotte’s kit, but this Four-Star catalyst was only available for a limited time from an event quest. If you do happen to have this weapon sitting around, then you should give it to Charlotte if you have no better options.
Specifically, this weapon’s passive activates whenever you use your Elemental Skill, which would be Charlotte’s camera ability. After using your skill, the character wielding this weapon has their Energy Recharge boosted by 48 percent for ten seconds, ensuring that you can always cast your Elemental Burst and heal your team.

3Skyward Atlas - Five-Star
Although Charlotte is certainly more suited to healing, that does not mean you can equip her with certain Five-Star weapons to boost her auto-attack damage. While almost any Five-Star catalyst will gift Charlotte with a sizable amount of Crit Rate or Damage, Skyward Atlas is the perfect catalyst for a hybrid build.
Since the healing provided by Charlotte’s Elemental Burst scales from her overall ATK percent, the massive buffs provided by this weapon will ensure that you are always healing a massive amount of damage, while also buffing your auto attacks. Specifically, the passive of this catalyst provides the active character with a 12 percent elemental damage increase and a chance to cause another instance of damage based on your overall ATK.

2Memory Of Dust - Five-Star
Memory of Dust is quite a unique catalyst because it requires you to constantly ruin a shielder such asLaylaorZhonglito fully utilize the weapon’s passive. Specifically, this weapon provides you with a four percent increase to your ATK whenever you damage an enemy with your basic attacks, stacking up to a 20 percent increase.
Most importantly, if your active character is protected by a shield while using the weapon, the buffs are increased by a whopping 100 percent. This means that you’re able to increase Charlotte’s damage and healing exponentially, so long as you can always keep a shield up.

1Prototype Amber - Four-Star
Prototype Amber is a catalyst that becomes available through the blacksmith very early on in the game, and is constantly outclassing Five-Star options whenever a new healer drops. While the HP this weapon provides does not help to buff Charlotte at all, the weapon’s passive synergizes with her kit perfectly.
While using Prototype Amber, you will recover 12 to 18 energy after six seconds, while everyone in your party will also regenerate six percent of their HP for the same six-second duration. Since Charlotte’s Elemental Burst is a party-wide heal, this weapon will be the best option for anyone looking to maximize her healing abilities.
