Being Sumeru's Archon, Nahida is naturally adept at using Dendro. She is a powerful catalyst user in Genshin Impact who takes advantage of Elemental Mastery to deal major damage to enemies. Her unique Elemental Skill lets her mark opponents to throw Dendro at, causing elemental reactions right after and doing even more damage.
Building up her Elemental Mastery is ideal. She can be an excellent support or DPS, and she's the one to go for if you're in need of more Dendro characters. Being a catalyst user, she has a lot of weapon choices that can work for her, both easy and hard to obtain.
8 Magic Guide - Three Star
If you need a weapon that you can get relatively easily for Nahida, this catalyst is a decent option. Its main stat gives you 41 to 187 points of Elemental Mastery, depending on its level, which is already pretty useful. On top of that, its passive ability increases the damage it does against enemies affected by Electro or Hydro by 12 to 24 percent, depending on its refinement rank.
This will help you deal damage in teams that focus on elemental reactions using Hydro, Electro, and Dendro, which can wipe enemies out in seconds. Plus, they're just fun to watch.
7 Sacrificial Fragments - Four Star
Right off the bat, this catalyst's main stat is Elemental Mastery, which is very beneficial for Nahida. It can give you 48 to 221 points of Elemental Mastery, depending on its level, which makes it much easier to get a good total. And, while not totally necessary for Nahida, Sacrificial Fragments' passive is beneficial.
It has a 40 to 80 percent chance of resetting her Elemental Skill's cooldown, depending on its refinement rank. This is great if you want to use it again quickly to take advantage of elemental reactions, but Nahida's Elemental Skill's cooldown isn't long enough to make it an absolute must.
6 The Widsith - Four Star
This catalyst's main stat gives Nahida an additional 12 to 55.1 percent CRIT DMG, which is awesome, as she does still need CRIT stats on top of her Elemental Mastery. Its passive can also be really useful, but it comes with certain conditions.
It randomly increases either her ATK, Elemental DMG, or Elemental Mastery when you switch to her. For almost any other character, pretty much any of those would benefit the character. But since Nahida is focused on Elemental Mastery, getting a boost in ATK won't help her as much as the other two options. So, using this weapon is a bit of a gamble every time. That said, an ATK boost isn't the worst thing you could give her.
5 Favonius Codex - Four Star
This weapon is a great choice if you prefer to have Nahida as an on-field DPS and watch her fight adorably. Its main stat gives her an extra ten to 45.9 percent Energy Recharge, which is important for having her Elemental Burst up as quickly as possible.
Its passive is what makes her better on-field, as it makes CRIT hits have a 60 to100 percent chance of producing some energy particles, depending on its refinement rank. For this weapon, having a relatively high CRIT Rate is important, too, to be able to take advantage of the passive. This helps the supports in the team recharge their Elemental Bursts quickly as well.
4 Mappa Mare - Four Star
This catalyst is craftable, so you can get it right away as long as you've got the billet. Its main stat gives 24 to 110 points of Elemental Mastery, which isn't as high as Sacrificial Fragments. However, its passive makes it a pretty good option if you like having Nahida on the field.
If she triggers an elemental reaction--which is what she's going to be doing most of the time anyway-- Mappa Mare's passive will give her an eight to 16 percent Elemental DMG Bonus, which can really help deal damage against enemies. This passive is useless if you don't plan on having her on the field most of the time, though.
3 Solar Pearl - Four Star
This catalyst is only obtainable from the Battle Pass, so whether it's easy to get depends on your budget. Nahida needs to be on the field to maximize its potential. Its main stat will give Nahida six to 27.6 percent CRIT Rate.
Its passive makes Normal Attack hits increase her Elemental Skill and Burst by 20 to 40 percent, depending on its refinement rank. Elemental Skill and Burst hits will also increase damage from Normal Attacks by 20 to 40 percent. Thus, it would be best to make Nahida your main DPS if you use this weapon.
2 Kagura's Verity - Five Star
This isn't Nahida's signature weapon, but it works pretty well for her. Its main stat gives her an extra 14.4 to 66.2 percent CRIT DMG, which is excellent. But its passive is where it shines. When she uses her Elemental Skill, her Elemental Skill DMG will increase by 12 to 24 percent for the next 16 seconds, depending on its refinement rank.
This can stack up to three times, though Nahida won't be able to reach that. Still, even powering up her Elemental Skill once will pack a punch, especially if it ends up being a CRIT hit.
1 A Thousand Floating Dreams - Five Star
Being Nahida's signature weapon, this will usually be her best option. Its main stat provides her with 58 to 265 points of Elemental Mastery, depending on its level, and its passive buffs Nahida differently based on the other party members.
She'll get 32 to 64 points of Elemental Mastery for each character who's also Dendro, and ten to 26 percent Dendro DMG Bonus for every character who's not Dendro. Every character besides her will also get 40 to 48 points of Elemental Mastery, depending on the weapon's refinement rank. This catalyst isn't needed for Nahida to be good, but it helps cover her bases and strengthen her Dendro damage.
