Honkai: Star Rail Feixiao Character Guide

Introduction

Feixiao is a DPS character who unleashes Ultimates via the Flying Aureus. The team can accumulate Flying Aureus stacks when attacking. Additionally, after a Party unit delivers an attack, Feixiao can launch a follow-up attack on the target as well.

Skills Overview

Basic Attack - Boltsunder

Deals Wind DMG equal to 50%—110% of Feixiao's ATK to a single target enemy.

Skill - Waraxe

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

Ultimate - Terrasplit

Deals Wind DMG to a single target enemy, up to 402%—759.6% 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%—172.8% of Feixiao's ATK to the target.

Ultimate - Boltsunder Blitz

Deals Wind DMG equal to 36%—64.8% of Feixiao's ATK to the chosen target. If the target is Weakness Broken, the DMG multiplier increases by 15%—33%.

Ultimate - Waraxe Skyward

Deals Wind DMG equal to 36%—64.8% of Feixiao's ATK to the chosen target. If the target is not Weakness Broken, the DMG multiplier increases by 15%—33%.

Talent - Thunderhunt

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 (including Feixiao's Basic Attack and Skill). Feixiao's Ultimate attacks do not count towards this number.

After Feixiao's teammates attack an enemy target, Feixiao immediately launches follow-up attack against the primary target, dealing Wind DMG equal to 55%—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%—66%, lasting for 2 turn(s).

Technique - Stormborn

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%.

Ascension 2 - 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."

Ascension 4 - 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%.

Ascension 6 - Boltcatch

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

TLDR

• The green arrow shows the "Flying Aureus" stack for her Ultimate.
• The red arrow shows the attack count. One attack (from any ally or Feixiao) on an enemy will light up half the circle. Once the circle is completed, Feixiao will gain 1 Flying Aureus.

Feixiao's huge damage comes from Ultimate and Follow-Up attacks from her Talent.
But unlike other characters, her Ultimate does not rely on energy, but on "Flying Aureus". You need to get a minimum of 6 stacks of Flying Aureus to activate her Ultimate. You can get these stacks by:
(1) 2 attacks by ally targets will provide 1 point of Flying Aureus
(2) Feixiao's Skill will provide 1 point of Flying Aureus
In short, you need a total of 12 attacks from the team so Feixiao can use her Ultimate. This may sound hard, but actually easy if you have the right teammates (Topaz, March 7th Hunt, Moze).

When you activate the Ultimate, you can see two buttons at the bottom right. This is both of Feixiao's Ultimate but can be used in different scenarios.
● If the enemy targeted is not Weakness Broken, choose the green arrow (Waraxe Skyward)
● If the enemy targeted is Weakness Broken, choose the red arrow (Boltsunder Blitz)

Now about her Follow-Up attacks from her Talent, it is slightly related to her Skill.
● Her Follow-Up attack can be triggered after Feixiao's teammates attack enemy targets. This effect can only trigger once per turn.
● However, her Skill will also instantly trigger her Follow-Up attack and reset the trigger count above.
