Honkai: Star Rail Feixiao Guide: Build, Teams & Mechanics

Who is Feixiao in Honkai: Star Rail?

Feixiao is a 5-star Wind Hunt character in Honkai: Star Rail. She serves as Merlin's Claw of the Xianzhou Yaoqing and one of the Seven Arbiter-Generals. She was once called Saran, a war slave of the Borisin. Now, she is widely respected by both soldiers and civilians of Xianzhou as "The Great General". Feixiao is direct, highly skilled in martial arts that honed herself into a supreme weapon.

Feixiao was officially released on January 14, 2025. As a Hunt-type DPS, she is good at dealing high single-target damage. Consider checking out Honkai: Star Rail Top Up for convenient resource options.

Feixiao's Unique Energy System

Flying Aureus Mechanics

Feixiao operates with a special energy system called Flying Aureus (Acheron is the first one). Here's how it works:

● Feixiao gains 1 Flying Aureus point for every 2 ally actions (6 points to activate her Ultimate)

● She can hold up to 12 points (two Ultimates' needs)

● Actions include follow-ups, Extra Actions, ally Ultimates, and even summon damage

● Only her Ultimate doesn't generate Flying Aureus points

Feixiao can work well without precise action management. You can use her Ultimate without worrying about wasting energy points.

Feixiao vs Acheron Energy Systems

Although both of them have unique energy mechanics, Feixiao's system is more flexible. Acheron allows only 3 points of overcap, while Feixiao can bank up to 6 extra points. This means Feixiao can use two Ultimates back-to-back if needed.

Best Feixiao Builds

Recommended Relics and Stats

Feixiao's build should focus on maximizing her single-target damage. So pick these:

Main stats: Go for CRIT Rate or CRIT DMG on the sphere, and ATK% or Energy Regen on the rope

Substats priority: CRIT Rate/DMG > ATK% > SPD > Effect Hit Rate

Best relic sets:

● 4-piece Musketeer of Wild Wheat: Increases Follow-up Attack DMG

● 4-piece Eagle of Twilight Line: Boosts Wind DMG and helps with Ultimate regeneration

● 2-piece Musketeer + 2-piece Space Sealing Station: A solid early-game option

Feixiao doesn’t need high Speed because most of her damage comes from her Ultimate. But if you want her to act more often, aim for SPD breakpoints like 134 or 143 to get more turns.

Feixiao’s Skills and Eidolons

Basic Attack

Feixiao’s basic attack delivers consistent damage to one target. And it will scale with her Attack.

Skill

Her skill focuses on powerful single-target strikes. And triggers a Follow-up Attack through her Talent. This is important because every Follow-up helps build Flying Aureus.

Ultimate

Feixiao’s ultimate delivers extremely high burst damage to a chosen enemy.

Talent

Feixiao’s Talent is one of the strongest in the game. It allows her to launch a Follow-up Attack whenever any ally hits an enemy. This attack gets a 60% DMG boost and counts toward her Ultimate energy. Even if the enemy died, the Follow-up still happens.

At Eidolon 6, her Talent will get even stronger. It makes her Follow-up Attack count as Ultimate DMG, and her Ultimate also ignores 20% of the enemy's resistance. This makes her one of the top single-target DPS characters.

Technique and Passive Effects

Feixiao’s Technique increases her Movement SPD and pulls enemies toward her. During this state, her attacks deal extra Wind DMG based on the number of enemies pulled.

Her Eidolons enhance her power significantly:

E2: Allies’ Follow-up Attacks give her Flying Aureus (up to 6 per turn)

E4: Doubles Toughness damage from her Talent and gives +8% SPD for 2 turns

E6: Major upgrade that boosts her Ultimate and makes her Talent hit like an Ultimate

Feixiao needs teammates who act often to build Flying Aureus fast. These supports are ideal:

Ruan Mei: Buffs team damage and extends enemy Weakness states

Jiaoqiu: Increases Ultimate DMG

Pela: Lowers enemies' DEF with her Ultimate

These characters help Feixiao charge her Ultimate faster while keeping the team alive.

Sub-DPS Partners for Maximum Output

Moze: Chains attacks and generates many actions
