Yanfei Dual Blaze Hydro Build Guide | Genshin Impact | Abyss Ready

In this Genshin Impact Guide I’m going to be showing you my Dual Hydro Build for Yanfei. It’s a Vaporize build, featuring Yelan and Xingqiu, as part of a team of three potent damage dealers. This build is meant to squeeze more frequent Vaporize procs from Yanfei enabling frequent Charged Attacks, which is a huge gain for damage.

This build adds a second off-field Hydro applier, who’s also a damage dealer. Thanks to the introduction of the five-star character, Yelan, we can finally unleash it’s full potential of Yanfei. Such a build is much more expensive resin-wise, as you have to build three full DPS characters. However, it enables an aggressive playstyle, with a higher damage ceiling. If this sounds like your kind of playstyle, it’s worth checking out.

Yanfei Dual Blaze Hydro Build Guide

It has been a year, since my last build for Yanfei. Back there, AOE content was dominant in the Spiral Abyss, and Inazuma was not out yet. An Overload team of Yanfei, Fischl and Beidou was optimal against most content. Nowadays, Spiral Abyss is full of bosses, so we draft a team tailored for a single target situation, and is still decent in AOE.

The idea is to apply an excessive amount of Hydro element on the enemy, by using both Yelan and Xingqiu. Their Hydro is applied from off-field when your active character does a normal attack. Yanfei has to go through normal attacks to build up “seals,” then at a max seal number, unleash her charged attack. So the goal is to Vaporize all charged attacks, for massive damage. With multiple hydro sources, you can fully utilize Yanfei‘s burst, which allows for seals to build much faster. Yanfei can therefore unleash Charged Attacks sooner, following two normal attacks instead of three. This will still vaporize the charged attack in the process.

Not only that, but she can also exploit the fact that she gains a full number of seals after using both, elemental skill, and burst. So you can unleash two extra charged attacks after one normal attack, for more Vaporize hits. Meanwhile, both Yelan and Xingqiu add their high single-target damage on top of Yanfei’s damage.

The ideal buffer support in the fourth team slot is Bennett, due to the fact he can buff Attack stats, add Pyro resonance for even more Attack, and help Yanfei generate energy for her burst. He also act as the healer, and wielder of either Noblesse Oblige or Instructor artifact sets, for more team buffs.

Enable Yanfei to proc more frequently meaning further damage for your team.

This build is ideally tuned for endgame content, and in this Guide I’ll explain just how to build a Dual Hydro Build using Yanfei. Perfect for conquering the open world, event challenges, as well as Spiral Abyss. I’ll go through what Weapons to use, what Artifacts to upgrade and which companions to pick.

Yanfei Dual Hydro Build Stats

With her being able to Vaporize most of her damage, Yanfei benefits more from Elemental Mastery (EM). So we go with EM as the main stat on Sands, Pyro Damage on Goblet, and Crit on circlet. You should aim for around 200-230 EM, but don’t go higher. If you are using a weapon with EM bonus, or have two pieces of the Wanderer’s Troupe, you should consider Attack Sands.

For Critical stats, you should aim for a balance ratio of 1 Crit Rate : 2 Crit Damage. If you have Yanfei at C2 or higher, you have to consider the additional 20% Crit Rate from this constellation. This bonus applies to enemies below 50% HP only, so it averages 10% in the overall calculations.

This encourages you to cap your Crit Rate (in character sheet) at 80%, so the extra 20% pushes it to 100%, and doesn’t waste any extra chances. However, if you have very high Crit damage (200% or higher), it’s still worth pushing Crit Rate beyond 80%.

If you play Yanfei on short rotation, and desire to use her burst on cooldown, you have to build some ER on her. However, I advise against wasting too many sub stats on ER. The better solution is to extend the rotation a little bit, to funnel energy from Bennet’s skill into Yanfei. Or just ignore her burst for the second rotation.

Yanfei Dual Hydro Build Weapon

The catalyst is a pure elemental weapon, so Yanfei has the benefit of dealing Pyro damage through Normal attacks, Charged Attacks, elemental skill, and burst. This allows her to deal proper damage with every part of her kit and enables generic Pyro builds to be so effective. It also promotes the usage of a wide variety of catalyst weapons.

Free and Craftable Four Star weapons

mappa mare catalyst weapon genshin impact wiki guideFrom the get-go, Mappa Mare is an excellent weapon for a Yanfei Vaporize build. It has one of the highest base attacks among four-star Catalyst (565), and has EM sub-stat. On top of that it has an elemental damage bonus that stacks up to 16% at base refinement one, and 32% at max refinement.

You can craft this weapon early in-game, and it will carry you to the endgame. If you don’t need refinement on other craftable Catalyst, feel free to refine it to the max. However, as you get more damage from other four-star weapons, such as The Widsith, you might consider saving the crafting material on Mappa Mare.

The ultimate weapon – Gasha 4 Star

the-widsith-catalyst-weapon-genshin-impact-wiki-guideThe Widsith is best Catalyst in the game for Yanfei, and at Refinement 5, it beat five-star Catalysts by a big margin. The weapon maintains its strength, even with downtime accounted for. So it really has no contender, and you should hold onto it once you get one. The Widsith has 510 base attack, and 55.1% Crit damage sub-stat, these values by themselves are very competitive in most scenarios. However, the true strength comes from the passive, which gives the active characters a random buff from three.

  • Recitative: ATK is increased by 60~120%.
  • Aria: Increases all Elemental DMG by 48~96%.
  • Interlude: Elemental Mastery is increased by 240~480.

Yanfei vaporize builds utilize all of the three buffs to the fullest, no matter which one it picks. The buff has 10-second duration, but 30-second cooldown. In an ideal rotation of 20 seconds, you will have buff in the first rotation, then miss it in second; then get it in the third, and so on. That’s an effective 50% uptime, with a very high damage value. The average damage of The Widsith over two rotation is still higher than all other weapons.

Gasha 5-Star Weapons

It’s ironic, but all five-star weapons are worse than The Widsith at max refinement. So you only use these five-star weapons on Yanfei if you don’t have The Widsith, or have it at one refinement.

The two weapons that are worth using are Kagura’s Verity, and Lost Prayer to the Sacred Winds. As they are better than R1 The Widsith, we can use them temporarily.

Yanfei Dual Hydro Build Artifacts

When it comes to Yanfei‘s choice of artifact, she’s very flexible and able to achieve a great result with a wide variety of artifacts.

Hybrid Set

Going with two pieces of one set, and two pieces from another is totally a viable option for Yanfei. You can easily mix and match sets with various bonuses, to give Yanfei the best sub-stats possible. Hybrid is not the best option in a fully optimized build at the very endgame. Some full sets have strong bonuses for Yanfei, with the four-piece set bonus being very desirable. However, hybrid is easier to get, more flexible and has the potential to give superior sub-stats.

You can pick one set that provides an 18% Attack with a two-piece bonus. These sets are Gladiator’s FinaleShimenawa’s Reminiscence, Vermillion Hereafter, and Echoes of an Offering. On the other hand, you have the option to go with either a 15% Pyro damage bonus from the Crimson Witch of Flames, or 80 EM from Wanderer’s Troupe. The other option is to just pick a different Attack set from among the four different sets.

I personally recommend a Hybrid set, rather than farming the Crimson Witch of Flames for months. This is the most efficient way to spend your Resin.

Wanderer’s Troupe

This set gives 80 EM as a two-piece bonus and gives a 35% Damage multiplier to Charged Attacks. Charged Attack is the major source of damage in Vaporize builds, it deals more than 60% of overall damage. So giving it a high multiplier from a Wanderer’s Troupe is a total damage increase in most scenarios.

However, acquiring good Wanderer’s Troupe pieces is different from farming other sets. Wanderer’s Troupe doesn’t drop from domains, and can’t be farmed. It only drops from the Weekly bosses and world bosses, but not in great numbers. You will get some from open-world exploration, and some from quest rewards. So in the early game, when you are short on resin (because you have to farm for characters’ ascension materials and talent levels) the Wanderer’s Troupe set will be the more accessible. At endgame, after levelling all characters and talents, you have enough resin to farm artifacts in the long term. At this point, you will start to feel there are not enough Wanderer’s Troupe pieces to compete with farmable sets.

So depending on where you are in progress, this set will be either a best in slot, or a lesser competitor.

Crimson Witch of Flames

On paper, Crimson Witch of Flames is the best set for any Pyro character playing as a vaporize build. It does much higher numbers (in an optimal setup), and it has several bonuses that fit the needs of Yanfei . It has a 15% Pyro damage bonus on the two-piece set, which will go up to 22.5% after using the elemental skill. The four-piece bonus has a 15% extra vaporize multiplier.

These bonuses are very competitive, and if paired with good sub-stats, it provides Yanfei with the highest damage possible. However, Hybrid sets can match or bypass it if it gets better sub-stats. So farming Crimson Witch of Flames for weeks or months is not the most resin-efficient decision to make. This is especially true with the Sumeru expansion. The newer domains and bosses will need resin. The Crimson Witch of Flames domain doesn’t have a good second set to justify farming there.

Yanfei Dual Hydro Build Talent Skills

Level talents in this order: Normal Attack > Elemental Burst > Elemental Skill.

Seal of Approval

Yanfei‘s normal and charged attacks do Pyro damage at range by nature. Her Normal attacks allow her to build up to three Seals at C0~5, and four at C6. Seals reduce stamina consumed by the next Charged Attack and increase its damage. So the aim is to build three seals, and unleash a Charged Attack afterwards.

During an Elemental Burst, one seal is granted passively to Yanfei every second. This extra seal allows Yanfei to unleash a charged attack with three seals, after two normal attacks instead of three. This change is huge, as it allows more charged attacks used within the burst uptime, for more Vaporize reaction, and higher damage. Note that Burst also increases Charged Attack damage.

Signed Edict

Elemental skill is a nine-cooldown talent, that deals Pyro damage in the AOE. It’s quick to cast and grants Yanfei maximum seals. It allows an extra Charged Attack to be used with high damage potential.

Make sure enemies are close to Yanfei before casting the elemental skill, because it has a shorter range than the rest of her kit.

Done Deal

Elemental Burst deals Pyro damage in the AOE, similar to the elemental skill. It also grants Yanfei maximum seals, and gives her a Charged Attack buff for 15 seconds, on a 20-second cooldown. At Constellation four, an elemental burst grants Yanfei a shield equal to 40% of her HP, for 15 seconds.

For the 15 seconds duration of the buff granted by her burst, Yanfei will generate a seal passively, every 1 second. This enables her to use Charged Attacks with full seals after two normal attacks.

Rotation and How Yanfei’s Vaporize Works

To fully utilize Yanfei in a dual hydro vaporize team, you need have a certain understanding of hidden mechanics in the game. These include understanding the internal cooldown and elemental gauge. I’ll go over a quick explanation of the basic concept here, and make a full dedicated guide in future.

Internal Cooldown (ICD)

In short, Elemental attacks don’t apply their corresponding element with each hit. Instead, they apply the element in the first hit, then go into cooldown before applying the element again.

The standard ICD for normal attacks of all characters are three hits and last 2.5 seconds. So if you spam normal attacks, in Yanfei’s case she finishes three hits in 90 frames (1.5 seconds), it will go as follows:

  • NA1: Apply pyro
  • NA2: Doesn’t apply Pyro
  • NA3: Doesn’t apply Pyro
  • NA1: Apply pyro (three-hit cooldown reset)
  • NA2: Doesn’t apply pyro
  • NA3: Apply Pyro (2.5 seconds cooldown reset)

It means that Yanfei effectively applies Pyro three times in three seconds from normal attacks only. If you add Charged Attacks, she will apply even more Pyro, because Charged Attacks has no ICD, to begin with, and can apply Pyro with every hit. So a basic two normal attacks followed by a charged attack repeated twice, will apply Pyro four times within three and a half seconds. Then she has the potential to apply Pyro a fifth and even a sixth time if she scores critical hits on her Charged attacks (which cause an extra attack from her C2).

So overall, Yanfei applies too much Pyro. To be able to vaporize all her hits or at least the most important ones, we need to understand the elemental gauge.

Pyro and Hydro Elemental Gauge

Elemental gauge is a simple mechanic in Genshin that allows elemental reactions in consuming varied portions of elements on enemies in the reaction. In every reaction, there’s a stronger element and a weaker element. If the stronger element is applied to the enemy, and the weaker element is used as a trigger for the reaction, it consumes only half of the element gauge on the enemy. This allows the element to persist for another reaction, and that’s the case of Reverse Vaporize.

In Reverse Vaporize, we apply the stronger element (Hydro) to enemies and proc the vaporize with the weaker element (Pyro). However, even with a Pyro consuming portion of Hydro aura, Yanfei’s Pyro application is still rapid, and one Hydro support can’t keep up. So we use two Hydro supports, with off-field hydro application, to enforce the hydro aura to stay put on enemies, even with Yanfei.

Yelan and Xingqiu only apply their hydro with active character’s Normal Attacks on 1 seconds cooldown. So we use both of them together to ensure two hydro application per second, and let Yanfei go wild with her Pyro application, and not miss Vaporize procs.

Optimal Yanfei Rotation to Maximize Damage

To exploit the double amount of Hydro application we get from using Dual hydro units, I’ve made some tests with Yanfei. The best result I could find is to use a Charged Attack at every chance possible, so we use an extra charged attack after Elemental Skill and after Elemental burst as well.

In an ideal scenario, you would start this rotation after you already Cast all Elemental Skills and Elemental Bursts of Yelan, Xingqiu, and Bennett. The rotation goes as follows (I’ll use “E” as the symbol for Elemental Skill, “Q” for “Burst”, “C” for Charged Attack, and “N 1, 2, 3” for normal attack)

  • Q > N1C > E > N1C > N2C > N2C > N2C > N2C > E > C

At C6, you get three Charged attacks with four seals and three Charged Attacks with three seals. At C5 or lower, you get all seven with three seals.

Yanfei Dual Hydro Build Team Composition

Genshin Impact has unique playstyles that rely on switching characters and chaining combos across these characters. So a solid part of this Yanfei vaporize build is knowing which characters will accompany her, and what roles they will play.

In this section, I’ll fill you in on some of the best characters that synergize well with this build. It’s universally recommended for you use a five-star support character, and the most suitable among them for this build is Yelan.


The latest addition to the Hydro roster, and the second off-field hydro support, along with Xingqiu. There’s no real need to compare the two, since we use them both and they’re not in competition. Yelan is an excellent support for Yanfei, that fills multiple roles in the team. She works as off-field DPS, who can dish out great damage without external buffs. At the same time, her off-field hydro application is necessary to play Vaporize.

Finally, Yelan buffs the active character on the field with a tremendous damage increase buff, that goes up to 50%. This buff keeps building up over time, so Yanfei is one of the few Pyro DPS in-game that takes full advantage of it. Yanfei’s damage is dynamic and doesn’t snapshot buffs, which allows her to update her damage with the increase in Yelan’s buff. Yanfei also stays on the field for longer, to take advantage of Yelan’s buff at higher values. Finally, Yelan adds mobility and allows fast repositioning to the team.

Make sure to level Yelan’s elemental burst as high as possible, to increase her DPS. After that, you are free to level her Elemental skill, but always skip leveling her Normal attack, it’s not important in this build.


Yelan will be doing a lot of damage in this team, so we focus only on her dps. Unlike Hu Tao who scales with Attack, and converts HP into Attack. Or Noelle who scales attack but converts it from Def. All of Yelan’s damage scales with HP , and its true scaling, where the HP stat directly scales damage without conversion. This type of scaling is very strong in Genshin, and yields very high damage for so little investment. Not to mention how HP stat is less contested by other characters, and easier to get.

For the best results, we prioritize %HPHydro DMG bonus, and Crit.  These are the stats that scale Yelan damage. Hydro DMG roll only on Goblet, Crit rolls only on Circlet, while HP can roll on Circlet, Goblet and Sands. So you always want HP% on Sands, Hydro on Goblet, and you are left with the choice between HP% and Crit on Circlet.

Usually the circlet with better sub-stats is better overall, so you have some flexibility on the main stat here.


The HP scaling on Yelan make the weapon base damage absolutely useless. That means five-star weapons are not better than four-star weapons, and both are not better than three-star weapons. What determines weapon usefulness for Yelan is the sub-stats, and weapon passive only. Among these, we seek either HP, ER, Burst damage, or Crit.

favonius bow bows weapon genshin impact wiki guideYelan has a very high energy recharge requirement, even with Xingqiu on the team. That makes weapons with energy recharge the absolute best pick. So the best weapon for her is Favonius Warbow, with the highest ER sub-stat among bows, and a passive that generates additional energy for herself and the entire team. Favonius Warbow gets more value at higher refinement, due to a higher chance to proc, and a shorter cooldown on the passive.

If you don’t have a Favonius Warbow, you can substitute with Fading Twilight, Elegy for the End, or Sacrificial Bow. These are ok choices, but Favonius Warbow is still the better pick.

recurve bow bows weapon genshin impact wiki guide

Using Energy Recharge Sands has a very high opportunity cost since you lose % HP stat that you can’t easily compensate with a weapon. But it’s possible if all else fails.

Recurve Bow is the only free weapon with an HP% sub-stat, but it doesn’t have a useful passive. So again, it’s not better than the Favonius Warbow.

Crit weapons are numerous, and come in all forms, from three stars to five stars. But usually, ER and HP weapons are just better. Even her signature weapon, Aqua Simulacra is only slightly better than Favonius Warbow. So I highly recommend against wishing for it, even if you have hundreds of extra wishes.


With the high ER Yelan can achieve, Emblem of Severed Fate becomes a very effective set for her. Yelan’s damage comes from Burst only, so the Emblem of Severed Fate gives her up to a 50% damage multiplier, or more, depending on the total ER she has.

It’s true, that Emblem of Severed Fate is highly contested by many characters. But Yelan needs pieces with HP% main and sub stats, so she doesn’t put much pressure on other characters.


Xingqiu is the original Hydro enabler to the Reverse Vaporize teams. Now Yelan is it competition with him over the role, but we just use them together in our build. Two hydro appliers enable Yanfei to Vaporize more frequently. On top of that, Xingqiu shreds enemies’ Hydro resistance, allowing Yelan to do more damage.

Xingqiu with the Sacrificial Sword generates good elemental particles, to help himself and Yelan recharge their burst. He also adds much more survivability to the team, with a damage reduction, small heals, and more importantly can resist interruptions. Yanfei will remain resistant to interruptions, so enemies don’t break her combos during Charged Attacks.


This team has a healer, so we don’t need any healing from Xingqiu, and can build a full-damage dealer instead.

With Yelan in this team, and Sacrificial Sword, Xingqiu requires less Energy Recharge, so we go for Attack on Sands, Hydro Damage on Goblet, and Crit Rate or Crit Damage on headpiece for main stats. For sub-stats, we go with Energy RechargeAttack, and Crit.


sacrificial-sword-sword-weapon-genshin-impact-wiki-guideI prefer to use the Sacrificial Sword for Xingqiu. It can reset the cooldown of Xingqiu‘s Elemental Skill, to use two casts instead of one. It gets better with a higher refinement level, so make sure to get more duplicates of this weapon.

Overall it’s the most reliable weapon, even though not the weapon dealing the highest damage.


Emblem of Severed Fate gives Xingqiu the best personal damage. However, Yanfei’s damage output is much more important. So we have the option to equip Xingqiu with Noblesse Oblige, for a slightly smaller damage, but a team-wide attack buff. It also decreases contests over the best Emblem of Severed Fate pieces.


Bennett is the main “Attack” buffer in Genshin Impact, and he’s in this team to maximize Yanfei’s damage. Paired with her, Bennett adds Pyro resonance, for an extra 25% attack. With the Instructor artifact set in tow, he can also buff EM for even higher damage. He’s the healer of the team as well.

In this team, we cast Bennett‘s elemental burst right before switching to Yanfei, to increase the time Yanfei stays buffed. The reason being is that Yanfei stays on the field longer than the duration of Bennett’s elemental burst.


The team has enough damage sources, so we build Bennett as a pure support. Focus on Energy Recharge to maximize the uptime of his Elemental Burst. You can fulfil his ER by using ER on the Timepiece, which frees up the weapon slots to have a higher base attack.

Bennett‘s Attack buff scales with his Base Attack, which comes from levelling and Ascending him, and his weapon. It is not affected by the flat or percentage Attack stat on Artifacts. So we should give him a sword with the highest base attack available.

On the other hand, to maximize his healing, we should give him HP and Healing Bonus stats.

The main stats on Bennett goes as follows: Healing Bonus on Circlet, Pyro Damage Bonus or % HP on Goblet, and ER on Sands. For sub-stats, go for what you want, either HP for more healing, or for Attack and crit for little extra damage.


prototype rancour sword weapon genshin impact wiki guideAll Energy recharge weapons for Bennett are decent. But in this team, with lower ER requirements, and longer rotation, we can just stick to an ER Timepiece, and use a higher base attack weapon.

For example the four-star swords with high base attacks are: Blackcliff Longsword from Paimon’s Bargains, the free weapon Prototype Rancour, and the limited banner The Alley Flash.

If you have got a five-star sword that no damage dealer is using, you can give it to Bennett. The increase in base attack will translate to a higher attack buff for the entire party, and yield a huge damage boost. That’s especially true if you’ve got a Skyward Blade, which has a high base attack, and Energy Recharge sub-stat.


Bennett is a classic support character who could either use good old Noblesse Oblige, to grant an attack buff for the entire party. Or just use Instructor to increase EM, while letting Xingqiu hold Noblesse Oblige.

We hope you found this build useful, and hopefully it gives you a good a better idea of how to maximize Yanfei’s potential.
