Introduction

Feixiao is a 5-Star Wind-Type character following the Path of The Hunt in Honkai: Star Rail that deals extraordinary amounts of Single-Target damage with her Ultimate. In place of Energy, her Ultimate revolves around generating points of “Flying Aureus,” which Feixiao gains when she or her allies perform attacks. Learn about Feixiao’s best Relics, best Light Cones, teams, and synergies in this Quick Guide.

Character Overview

Pros

Exceptional single-target damage and Toughness DMG
Strong synergy with existing follow-up attackers and buffers (Topaz, March 7th, Robin)
Good existing Light Cone and Relic/Planar options

Cons

Single-target attacks can be inefficient in scenarios with many enemies, like Pure Fiction
Dr. Ratio performs a similar role, and many players obtained him for free

Playstyles

Feixiao relies on her single-target Ultimate and frequent follow-up attacks to deal the majority of her damage. She should use her Skill as often as possible in order to both trigger additional follow-up attacks and to maximize the team’s attack frequency.

Basic ATK

Basic ATK | Boltsunder

Trace Description

Boltsunder [Single Target]

Deals Wind DMG equal to 50%/100%/110% of Feixiao’s ATK to a single target enemy.

Standard Basic ATK. Feixiao won’t be using this often.

Skill

Skill | Waraxe

Trace Description

Waraxe [Single Target]

Deals Wind DMG equal to 100%/200%/220% of Feixiao’s ATK to a single target enemy. Then, immediately launches 1 extra instance of Talent’s follow-up attack against the target.

In addition to dealing damage, Feixiao will also launch her Talent’s follow-up attack after using her Skill. This allows her to generate one full point of “Flying Aureus” per Skill use.

Ultimate

Ultimate | Terrasplit

Trace Description

Terrasplit [Single Target]

Deals Wind DMG to a single target enemy, up to 402%/700%/760% of Feixiao’s ATK. During this time, can ignore Weakness Type to reduce the target’s Toughness. When the target is not Weakness Broken, Feixiao’s Weakness Break Efficiency increases by 100%.
During the attack, Feixiao first launches “Boltsunder Blitz” or “Waraxe Skyward” on the target, for a total of 6 time(s).
At the end, deals Wind DMG equal to 96%/160%/173% of Feixiao’s ATK to the target.

Boltsunder Blitz [Single Target]
Deals Wind DMG equal to 36%/60%/65% of Feixiao’s ATK to the chosen target. If the target is Weakness Broken, the DMG multiplier increases by 15%/30%/33%.

Waraxe Skyward [Single Target]
Deals Wind DMG equal to 36%/60%/65% of Feixiao’s ATK to the chosen target. If the target is not Weakness Broken, the DMG multiplier increases by 15%/30%/33%.

Feixiao’s main source of damage. Her Ultimate does not operate on a standard Energy gauge, but instead, she gains points of “Flying Aureus” when she or her teammates attack enemy targets.

Note: Feixiao can store up to 13 points of “Flying Aureus” (the indicator goes up to 12, but it is possible to store 12 plus one more full point), while her Ultimate costs 6 points. This allows her to save her Ultimate, which can be useful in scenarios where she needs to wait for buffs or where her Ultimate would overkill an enemy.

Talent

Talent | Thunderhunt

Trace Description

Thunderhunt [Single Target]

Can activate Ultimate when “Flying Aureus” reaches 6 points, accumulating up to 12 points. Feixiao gains 1 point of “Flying Aureus” for every 2 attacks by ally targets. Feixiao’s Ultimate attacks do not count towards this number.
After Feixiao’s teammates attack enemy targets, Feixiao immediately launches follow-up attack against the primary target, dealing Wind DMG equal to 55%/110%/121% of Feixiao’s ATK. If there is no primary target available to attack, Feixiao attacks a single random enemy instead. This effect can only trigger once per turn and the trigger count resets at the start of Feixiao’s turn. When using this attack, increases DMG dealt by this unit by 30%/60%/66%, lasting for 2 turn(s).

Feixiao’s Talent follow-up attack allows her to generate “Flying Aureus” when she uses her Skill, or when her allies attack. The damage from this follow-up attack makes up a rather modest portion of her overall damage.

The fact that this follow-up attack will launch at a random enemy if the original target dies allows Feixiao to handle multiple targets to some degree.

Technique

Technique | Stormborn

Trace Description

Stormborn [Enhance]

After using Technique, enters the “Onrush” state, lasting for 20 seconds. While in “Onrush,” pulls in enemies within a certain range, and increases this unit’s movement speed by 50%. After entering battle, gains 1 point(s) of “Flying Aureus.”
While in “Onrush,” actively attacking will start battle with all pulled enemies. After entering battle, deals Wind DMG equal to 200% of Feixiao’s ATK to all enemies at the start of each wave. This DMG is guaranteed to CRIT. If more than 1 enemy is pulled in, increases the multiplier of this DMG by 100% for each additional enemy pulled in, up to a maximum of 1000%.

Pay-to-win Yukong and the actual objectively funniest technique in the game (sorry, Yunli). The damage of the Technique — which scales with the number of enemies caught in the tornado — can be useful in overworld combat, but is otherwise just a funny quirk of the Technique.

Note: Feixiao’s Technique DMG counts as an attack and does give her one point of “Flying Aureus”.

A2 Bonus

Ascension 2 Bonus Ability | Heavenpath

Trace Description

Heavenpath

When the battle starts, gains 3 point(s) of “Flying Aureus.”
At the start of a turn, if no follow-up attack was launched via Talent in the previous turn, then this counts as 1 toward the number of attacks required to gain “Flying Aureus.”

Allows Feixiao to perform her Ultimate earlier in the battle. The extra half-point of “Flying Aureus” gained when her follow-up attack is not launched is usually only relevant in teams with Bronya, where Feixiao’s teammates may sometimes be unable to trigger her follow-up attack before Feixiao’s next turn starts. This can occur when Bronya is played in a “Slow” playstyle. For more information on this playstyle, please visit the Bronya Guide.

A4 Bonus

Ascension 4 Bonus Ability | Formshift

Trace Description

Formshift

When using Ultimate to deal DMG to an enemy target, it is considered as a follow-up attack. Follow-up attacks’ CRIT DMG increases by 36%.

Feixiao’s Ultimate being considered a follow-up attack is important for her synergy with units that buff or benefit from follow-up attacks like Topaz, Aventurine, or Robin. The extra CRIT DMG is nice as well.

A6 Bonus

Ascension 6 Bonus Ability | Boltcatch

Trace Description

Boltcatch

When using Skill, increases ATK by 48%, lasting for 3 turn(s).

An effectively permanent 48% ATK buff for Feixiao.

Note: Trace levels shown are 1/10/12 (Basic ATK 1/6/7).

Trace Priority

>> >

Ultimate >> Talent > Skill

Feixiao should avoid using her Basic ATK, so it can remain unleveled.

Eidolons

Eidolon 1

Eidolon 2

Eidolon 3

Eidolon 4

Eidolon 5

Eidolon 6

Eidolon 1

Eidolon 1 | Skyward I Quell

Eidolon Description

After launching “Boltsunder Blitz” or “Waraxe Skyward,” additionally increases the Ultimate DMG dealt by Feixiao by an amount equal to 10% of the original DMG, stacking up to 5 time(s) and lasting until the end of the Ultimate action.

Buffs Feixiao’s main source of damage. This Eidolon multiplies the base damage of each hit, meaning its value is never diminished by buffs.

Damage Increase Over E0: ~23%

Eidolon 2

Eidolon 2 | Moonward I Wish

Eidolon Description

In the Talent’s effect, for every 1 instance of follow-up attack launched by ally targets, Feixiao gains 1 point of “Flying Aureus.” This effect can trigger up to 6 time(s) per turn.

Allows Feixiao to charge her Ultimate much faster and improves her synergy with units that can launch follow-up attacks, such as Topaz and Aventurine.

Note: Instead of adding one point of “Flying Aureus” per follow-up attack as the wording implies, this Eidolon adds one half-point of “Flying Aureus” per follow-up attack, so that follow-up attacks now generate one point total rather than one half-point.

Damage Increase Over Previous: ~45%

Damage Increase Over E0: ~77%

Eidolon 3

Eidolon 3 | Starward I Bode

Eidolon Description

Ultimate Lv. +2, up to a maximum of Lv. 15.
Basic ATK Lv. +1, up to a maximum of Lv. 10.

Buffs Feixiao’s main source of damage, but not as much as her E1 does.

Damage Increase Over Previous: ~8%

Damage Increase Over E0: ~92%

Eidolon 4

Eidolon 4 | Stormward I Hear

Eidolon Description

The Toughness Reduction from the Talent’s Follow-up ATK increases by 100% and, when launched, increases this unit’s SPD by 8%, lasting for 2 turn(s).

While Feixiao is not a Break-focused damage dealer, increasing her Talent follow-up attack’s Weakness Break Efficiency does slightly increase the team’s damage and survivability. The 8% SPD buff is also nice for allowing Feixiao to generate “Flying Aureus” faster.

However, these buffs are ultimately pretty marginal; the only reason to go for this Eidolon is to get Feixiao’s E6.

* E4 didn’t make a difference in damage in the calculations done for this guide, but can make a small difference under different assumptions.

Damage Increase Over Previous: 0%*

Damage Increase Over E0: ~92%*

Eidolon 5

Eidolon 5 | Heavenward I Leap

Eidolon Description

Skill Lv. +2, up to a maximum of Lv. 15.
Talent Lv. +2, up to a maximum of Lv. 15.

Small damage boost.

Damage Increase Over Previous: ~3%

Damage Increase Over E0: ~99%

Eidolon 6

Eidolon 6 | Homeward I Near

Eidolon Description

Increases the All-Type RES PEN of Ultimate DMG dealt by Feixiao by 20%. Talent’s follow-up attack DMG is considered as Ultimate DMG at the same time, and its DMG multiplier increases by 140%.

Nice boost to Feixiao’s Ultimate damage, and allows her Talent follow-up attack to become a mini-nuke of its own. This Eidolon makes Feixiao less reliant on her Ultimate for dealing damage, although her Ultimate will still deal a lot more damage than her Talent follow-up attack.

Damage Increase Over Previous: ~49%

Damage Increase Over E0: ~197%

E2 is the best stopping point for Feixiao. E3 and beyond are only stepping stones toward Feixiao’s E6.

Build

Light Cones

When using Feixiao with a secondary damage dealer following the Path of The Hunt, Feixiao should use the stronger Light Cone, given that Feixiao’s damage makes up a much larger portion of the damage in her teams than the damage dealt by any Hunt secondary damage dealer.

Note: Calculations done in a team with Feixiao, Topaz, Robin, and Gallagher assuming Feixiao with Duran, Dynasty of Running Wolves and 4-Pc The Wind Soaring Valorous.

Stats

Body	Boots	Sphere	Rope
CRIT	ATK% \| SPD*	Wind DMG Boost	ATK%

Substats

SPD (Until desired value)* ≈ CRIT > ATK%

* The amount of SPD you should build on Feixiao depends on a number of factors: SPD-sensitive teammates (e.g., Bronya, Robin, other follow-up attackers), the number of cycles required to clear a stage in Memory of Chaos or the score required to clear Apocalyptic Shadow, or even the SPD of a specific enemy you wish to outspeed. In most cases, however, more SPD can only help you.

Notable Synergies

Supportive Follow-up Attackers

Supports

Sustains

The Auto Button

Feixiao needs to press many buttons when using her Ultimate. Turning on autobattle during her Ultimate can help save your fingers.

Teams

Dual Damage Dealer

Feixiao — Supportive Follow-Up Attacker — Support — Sustain

These teams pair Feixiao up with a follow-up attacker with supportive utility (like Topaz, March 7th (The Hunt), and Moze), a support with partywide buffs or debuffs, and a sustain.

The follow-up attacker provides Feixiao points of “Flying Aureus,” some personal damage, and a moderate damage increase for Feixiao, while the support increases the damage and attack frequency of both.

Example Teams

Topaz’s Vulnerability debuff is valuable for Feixiao, and her frequent follow-up attacks generate points of “Flying Aureus.” Robin provides Action Advance, a huge DMG Boost, ATK, and Additional DMG procs for the team, while Aventurine provides debuffs to increase team damage and follow-up attacks to generate more points of “Flying Aureus.”

Feixiao — March 7th (The Hunt) — Bronya — Gallagher

A more F2P-friendly version of a dual damage dealer Feixiao team. March 7th (The Hunt) attacks very frequently with her E2 and personal Action Advance, allowing her to generate many points of “Flying Aureus” for Feixiao. In turn, Feixiao’s frequent attacks generate Charge for March 7th, giving her more frequent Enhanced Basic ATKs. Gallagher’s frequent attacks also generate “Flying Aureus” for Feixiao, while Bronya buffs Feixiao and allows her to take more turns.

Feixiao — March 7th (The Hunt) — Moze — Luocha

A team that functions similarly to the ones above, except with two supportive damage dealers instead of one. Luocha can use Multiplication to act more frequently for additional “Flying Aureus,” or Quid Pro Quo if additional energy for Feixiao’s teammates is necessary.

Feixiao — March 7th (The Hunt) — Asta — Lynx

A F2P team for Feixiao. March 7th buffs and attacks, Lynx sustains, and Asta gives the whole team a sizable ATK% buff and SPD increase. Lynx should use her Basic ATK as often as possible, as it is her only means of generating points of “Flying Aureus.” As with the above teams, Multiplication can allow Lynx to act more frequently.

Hypercarry Feixiao

Hypercarry Feixiao teams focus on buffing Feixiao’s damage using two buff-focused supports, with at least one support typically offering Action Advance so that Feixiao can take more turns to deal more damage and generate more “Flying Aureus.”

This team benefits from having a support or sustain capable of attacking frequently enough to trigger the follow-up attack from Feixiao’s Talent, although this isn’t strictly necessary.

Example Teams

Feixiao gets to act much more often because of Bronya. E1 and S1 Bronya are highly desirable for this team given the high Skill Point consumption. Feixiao may need to use her Basic ATK occasionally if SP gets too low — if so, it’s best for her to do so before Bronya Advances Feixiao, instead of after.

The classic Sparkle-Bronya duo works for Feixiao too. While neither Sparkle nor Bronya attack in this team, they accelerate Feixiao’s turn frequently and grant her very strong buffs. Gallagher’s attacks generate “Flying Aureus” and trigger Feixiao’s follow-up attacks. Feixiao’s A6 Bonus Ability comes in handy in this team, because Sparkle and Bronya do not attack and Gallagher can usually only trigger one of Feixiao’s follow-up attacks per two of her turns.

A much more F2P-friendly team. Hanya attacks on every turn, generates SP, and buffs Feixiao. Pela reduces enemy DEF and attacks with her Skill and Ultimate to help Feixiao generate “Flying Aureus.” Luocha and Hanya generate enough SP that Pela can use her Skill on every turn for a 2-turn Ultimate, increasing her Ultimate’s debuff uptime and generating “Flying Aureus” faster.

Changelog

10 September 2024 – Published for v2.5

Light Cone	Damage	Notes
I Venture Forth to Hunt	~120%	Feixiao’s signature Light Cone provides a decent CRIT Rate buff. On Feixiao, its DEF Ignore should always be fully stacked, as Feixiao launches multiple follow-up attacks in a single turn.
Baptism of Pure Thought	~116%	Not only can Feixiao be played in the same place as Dr. Ratio in follow-up teams, she can also use his signature Light Cone. Baptism of Pure Thought works very well on Feixiao, to such a point that it’s only marginally worse than Feixiao’s own signature Light Cone. However, Dr. Ratio’s Light Cone does require three debuffs to achieve its maximum effect, which is not achievable in some Feixiao teams (e.g. teams with March 7th (The Hunt) as the secondary damage dealer, or a Feixiao/Bronya/Robin team).
Worrisome, Blissful	~108%*	Feixiao can also use Topaz’s signature Light Cone. Her ability to launch two follow-up attacks in a single turn allows her to fully stack the Light Cone’s effect quickly. * Does not reflect the damage increase for allies.
In the Night	~102%	The CRIT DMG and CRIT Rate buffs that this Light Cone provides are good for Feixiao, although it does not buff follow-up attacks at all, making it the worst of the premium 5-star Light Cone options. It can be worse than Cruising in the Stellar Sea without SPD Boots.
Cruising in the Stellar Sea	100%	Feixiao’s best F2P option. The two below 4-star options are competitive with Cruising in the Stellar Sea if their conditions can be met.
Swordplay	~99%	About equal to Only Silence Remains assuming few or no target changes, and only marginally worse than Cruising in the Stellar Sea. The condition of “few or no target changes” can sometimes be difficult to maintain since Feixiao’s Talent follow-up attack can hit targets other than the primary target when triggered by an AoE attack such as Aventurine’s follow-up attack.
Only Silence Remains	~98%	About equal to Swordplay when facing one or two enemies.

Relic Set	Damage	Notes
4-Pc The Wind-Soaring Valorous	100%	Feixiao’s “signature” Relic Set. Its Ultimate DMG boost effect is always active on her.
4-Pc The Ashblazing Grand Duke	97%	Although Feixiao’s Talent follow-up attack only hits once, Feixiao can still stack the ATK% boost well with her Ultimate, and the 20% follow-up attack DMG Boost from the 2-Pc effect remains useful.
2-Pc Combinations	~93–95%	Feixiao can use a combination of 2-Pc Relic Sets, including 2-Pc The Ashblazing Grand Duke, 2-Pc Pioneer Diver of Dead Waters, 2-Pc Eagle of Twilight Line, or any 2-Pc ATK-Boosting Relic Sets. These combinations are generally similar in damage, although it should be noted that the 2-Pc Relic Sets that boost DMG% marginally outperform the 2-Pc Relic Sets that boost ATK%.
4-Pc Eagle of Twilight Line	Variable	4-Piece Eagle of Twilight Line is an option for low cycle Memory of Chaos/Pure Fiction and low Action Value Apocalyptic Shadow clears, and can be an excellent option for E2 Feixiao especially, given her increased Ultimate frequency with the Eidolon.

Planar Ornament	Damage	Notes
Duran, Dynasty of Running Wolves	100%	Feixiao’s best Planar Ornament. Feixiao and her allies frequently use follow-up attacks, allowing her to reach 5 stacks very quickly.
Izumo Gensei and Takama Divine Realm	~96%	Feixiao pairs well with other units following the Path of The Hunt, making this set’s condition easy to fulfill for a free 12% CRIT Rate.
Inert Salsotto	~95%	Provides strong unconditional buffs to Feixiao’s main sources of damage. Note: it does not double its DMG Boost on attacks that are considered both Ultimate and follow-up attacks.

Topaz & Numby	Topaz provides some personal damage and a follow-up attack DMG Vulnerability debuff that nearly all of Feixiao’s damage benefits from. Numby’s frequent attacks also generate points of “Flying Aureus” very quickly.
March 7th (The Hunt)	March 7th (The Hunt) can buff Feixiao’s SPD and CRIT DMG. Feixiao is also a great Master for March as her frequent attacks allow March’s Talent to trigger frequently, which consequently allows March to generate more points of “Flying Aureus” for Feixiao. With March’s second Eidolon, she can also provide further points of “Flying Aureus” for Feixiao through her additional follow-up attack.
Moze (we dont have an emoji sorry)	Like Topaz, Moze provides some personal damage and a follow-up attack DMG Vulnerability debuff which benefits nearly all of Feixiao’s damage. With Moze’s E2, he also increases CRIT DMG dealt to the target marked by his Skill. However, unlike Topaz, Moze’s debuff uptime requires more attention due to its dependency on the Departed state.

Robin	Robin’s strong partywide buffs and Action Advance more than make up for her low attack frequency. Feixiao’s teams typically include other follow-up attackers, and Robin is especially potent when paired with other teammates that can perform multiple attacks during their turns, since such teammates will be able to generate “Flying Aureus” even faster. Additionally, Feixiao and any supportive follow-up attackers she’s paired with can attack multiple times per turn to trigger Robin’s Additional DMG very frequently.
Bronya	Besides providing significant damage buffs to Feixiao, Bronya can also help Feixiao take more turns, which allows Feixiao and her teammates to generate “Flying Aureus” faster. Since Feixiao and Bronya are both Wind-Type, Bronya can also use Penacony, Land of the Dreams to provide a small Wind DMG Boost. At E4, Bronya becomes an even more effective support for Feixiao, as the follow-up attack from Bronya’s E4 can generate “Flying Aureus” for Feixiao and also trigger Feixiao’s Talent follow-up attack.
Sparkle	Sparkle has an Action Advance on her Skill, generous CRIT DMG and DMG% buffs, and generates Skill Points with her Ultimate. Although she cannot give Feixiao as many turns as Bronya can, Sparkle is still a good pick in the right circumstances.
Hanya, Asta	4-Star support options for Feixiao. Hanya and Asta both attack with their Skill and Basic ATK, and provide SPD and damage buffs. Hanya generates Skill Points for Feixiao, while Asta’s SPD buff is teamwide, allowing her and her teammates to generate points of “Flying Aureus” faster.
