Baizhu is Liyue's second-ever Dendro character and its first-ever five-star Dendro character. As a master of medicine, it's no surprise that his kit focuses on healing. He also has shielding capabilities and easy Dendro applications as a Catalyst user, so he makes for a top-notch support unit.

Like most healers in Genshin Impact, Baizhu's skills become stronger the higher his Max HP is. But you'll also want to prioritize his Energy Recharge and maybe even add a bit of Elemental Mastery so that he can really reach his full potential. Luckily, there are a lot of weapons that suit him quite well.

6 Thrilling Tales Of Dragon Slayers - Three-Star

This weapon is always a surprisingly good choice for Catalyst users whose skills are based on their Max HP, especially if they're supports. It's an easy weapon to obtain and refine, and it does the job well, especially if you're just starting out.

Thrilling Tales can raise Baizhu's Max HP by 7.7 to 35.2 percent, depending on its level. Its passive skill also raises the ATK of the character Baizhu switches to by 24 to 48 percent for ten seconds. With this weapon, you'll be giving Baizhu a boost in his healing and shielding, as well as letting him boost the ATK of your team's main DPS.

5 Fruit Of Fulfillment - Four-Star

If you've got enough HP from artifacts and would rather focus on other important stats, the forgeable Fruit of Fulfillment can be quite useful. It gives Baizhu a ten to 45.9 percent boost in his Energy Recharge depending on its level, which takes away a lot of the burden of Energy Recharge requirements.

Its passive skill gives him more Elemental Mastery at the cost of ATK, but the percentage is negligible and Baizhu doesn't need much ATK anyway. Depending on the weapon's refinement, it'll give him 24 to 36 extra Elemental Mastery points when he does an elemental reaction. Since Baizhu's a Catalyst user, he can trigger elemental reactions pretty quickly, allowing this weapon to give him an easy increase in both Energy Recharge and Elemental Mastery.

4 Prototype Amber - Four-Star

This forgeable catalyst might be the best free option for Baizhu, as it pretty much perfectly supports his kit. Prototype Amber raises his Max HP by nine to 41.3 percent, depending on its level. Its passive skill gives him four to six energy particles for six seconds every time he uses his Elemental Burst, allowing him to use it even more frequently and feed into the positive cycle.

It also periodically heals the whole team by four to six percent of their HP for six seconds, pushing Baizhu's healing capabilities even further. With both HP and Energy Recharge being taken care of with this weapon, it allows Baizhu to shine as a healer and support unit.

3 Favonius Codex - Four-Star

This weapon is perfect if you're sorely lacking in the Energy Recharge department for Baizhu. Not only does it give him a 10 to 45.9 percent Energy Recharge boost just by equipping it, but its passive skill can restore six Energy to the active character when he gets a critical hit in. The chance of it triggering starts at 60 percent and can go as far as 100 percent.

Of course, if you're playing him as a pure support unit, you probably won't be worrying about his CRIT Rate. However, if you prefer to have him on the field, investing in his CRIT Rate for this weapon is a fine decision. Otherwise, you can just switch him out so that the character of your choosing has their Energy restored instead, making Favonius Codex a flexible choice.

2 Everlasting Moonglow - Five-Star

This Catalyst is Kokomi's signature weapon, but it's still great for other healers, including Baizhu. It would give him a 10.8 to 49.6 percent raise in HP, and its passive skill does plenty of things that round him out well. First, his Healing Bonus would be increased by ten to 20 percent depending on its refinement. That coupled with the Max HP gain makes for awesome healing.

It also increases the damage of his normal attacks by one to three percent of his Max HP, giving him some decent DPS potential. Finally, after using his Elemental Burst, every normal attack he lands will restore 0.6 Energy for 12 seconds. This weapon basically makes him a great healer who can use his Elemental Burst more often, with the added bonus of giving him damage capabilities if you want to play him on-field.

1 Jadefall's Splendor - Five-Star

One of Baizhu's best weapons will obviously be his signature one, since it's literally made for him. Jadefall's Splendor gives him the same Max HP increase as Everlasting Moonglow, but its passive skill focuses a little more on damage output. Raising a shield or using his Burst will cast Primordial Jade Regalia on Baizhu for three seconds, and this has multiple effects.

4.5 to 6.5 of his Energy will be restored, and he'll gain a 0.3 to one percent Dendro DMG bonus for every 1,000 HP he has. This bonus can hit a maximum of 12 to 44 percent, depending on the weapon's refinement. The passive skill still works off-field, so you can still just quickly switch Baizhu in and out if you want. But this weapon gives him room to hit hard with Dendro, as well as raising his healing and shielding power and frequency.
