Honkai Star Rail: Best Fugue Build Guide

Fugue is the latest 5-star Nihility character in Honkai: Star Rail, bringing a unique approach to the Break Effect meta that has been a defining trend throughout the 2.X versions. Unlike previous Break and Super Break-focused units, Fugue is more of a support-oriented character, designed to enhance the damage output of Break Effect allies rather than dealing direct Break damage herself.

Her core mechanic revolves around Exo Toughness, a special effect that allows enemies to be broken twice, significantly increasing the effectiveness of Break-based teams. While her Super Break DMG isn’t as high as the Harmony Trailblazer’s, she makes up for it with powerful DEF reduction debuffs and the ability to bypass Weakness Types, ensuring her allies can consistently apply Break damage regardless of enemy resistances.

With her unique support toolkit, Fugue is easily one of the best Break Effect enablers, making her a valuable addition to any team centered around Weakness Break mechanics. Below, we’ll cover the best ways to build her, including optimal Light Cones, Relics, skill priorities, and team compositions to maximize her potential.

Fugue Overview

• Name: Fugue
• Rarity: 5-star
• Element: Fire
• Path: Nihility
• VA (JP): Yūki Takada

Level 80 Stats:
• HP: 1125
• ATK: 582
• DEF: 557
• Speed: 102

Fugue is a top-tier Nihility support specializing in Break Effect amplification. Her Exo Toughness mechanic, tied to her Talent, enables allies to break enemies twice, significantly boosting Break teams’ overall damage potential.

Her Skill enhances an ally for three of her turns, increasing Break Effect by up to 30%, allowing them to ignore Weakness Types, and retaining 50% of their Toughness Reduction, making her an invaluable asset in Weakness Break-focused compositions.

Additionally, Fugue’s Enhanced Basic Attack reduces enemy DEF by up to 18%, further amplifying team-wide damage output. However, her Ultimate is the weakest part of her kit, offering mediocre damage and Toughness reduction that bypasses Weakness Types, but it lacks the high-impact effects of her other abilities.

Overall, Fugue is an essential support for Break Effect teams, perfectly complementing Penacony’s roster of Break-heavy characters. If you’ve been investing in Break Effect strategies, Fugue is an excellent addition to take your team’s damage to the next level.

Best Light Cones for Fugue In HSR

Fugue benefits the most from her signature Light Cone, Long Road Leads Home, as it enhances both her Break Effect and team-wide Break DMG, making it the optimal choice for her kit. However, if you don’t have access to it, there are still solid alternatives that can complement her playstyle effectively.

Recommended Light Cones for Fugue:
1. Long Road Leads Home (Best-in-Slot) – Increases Break Effect by 60% and, when an enemy’s Weakness is broken, inflicts “Charring”, which increases Break DMG taken by 18% for two turns. This effect stacks twice, further amplifying her team’s damage potential.
2. Resolution Shines As Pearls of Sweat (Great Alternative) – When the wearer hits an enemy, there is a 60% base chance to apply “Ensnare”, reducing the target’s DEF by 12% for one turn. While it lacks direct Break Effect boosts, it still synergizes well with Fugue’s DEF reduction debuffs, making it a decent secondary choice.
3. Solitary Healing (Best F2P Option) – Increases Break Effect by 20% and boosts DoT damage for two turns after using an Ultimate. Additionally, defeating an enemy suffering from Fugue’s DoT restores 4 Energy, slightly improving her energy economy. This is a viable budget option, though it leans more toward DoT-based playstyles.

While Long Road Leads Home is the ideal Light Cone for maximizing Fugue’s Break support potential, Resolution Shines As Pearls of Sweat offers a strong secondary option, and Solitary Healing provides a practical F2P-friendly alternative for those without premium choices.

Best Relics For Fugue In HSR

Currently, there isn’t a relic set that perfectly complements Fugue’s entire kit, but the Iron Cavalry Against the Scourge (4-piece set) is the best available option for enhancing her Break Effect while also slightly boosting her personal damage.

For Planar Ornaments, Forge of the Kalpagni Lantern (2-piece set) is the optimal choice, further increasing her Break Effect and reinforcing her support capabilities.

Recommended Relic Sets:

Main Relic Set (4-piece Bonus)
• Iron Cavalry Against the Scourge (4-piece) – Enhances Break Effect and provides a slight damage boost, making it the best available choice for Fugue.

Planar Ornament Set (2-piece Bonus)
• Forge of the Kalpagni Lantern (2-piece) – Further boosts Break Effect, maximizing Fugue’s effectiveness in Break-focused teams.

Optimal Main Stats:

Relics:
• Body: Effect Hit Rate
• Feet: Speed

Substat Priority:
Effect Hit Rate (Until 67%) > Break Effect (Until 220% or 250% with Iron Cavalry) > SPD

Planar Ornaments:
• Planar Sphere: HP% / DEF%
• Link Rope: Break Effect

Substat Priority:
Effect Hit Rate (Until 67%) > Break Effect (Until 220% or 250% with Iron Cavalry) > SPD

With this setup, Fugue will be able to consistently apply her debuffs, maximize Break DMG output, and effectively support her team. While Iron Cavalry Against the Scourge isn’t a perfect fit, it remains the best available option to enhance her Break Effect-focused playstyle.

Fugue Skill Priority

To maximize Fugue’s impact as a Break Effect support, her Talent should be the top priority, as it is the core of her kit, allowing her to apply Exo Toughness and enable double Breaks. After that, her Skill should be upgraded next, since it boosts an ally’s Break Effect and lets them ignore Weakness Types, significantly increasing overall team damage.

Her Ultimate comes next, as while it provides Toughness reduction regardless of Weakness Type, its damage output is relatively low compared to her other abilities. Basic Attacks should be leveled last, as they are the least impactful part of her kit.

Optimal Skill Leveling Order:
1. Talent – Core of her abilities, enabling double Breaks and boosting Break DMG.
2. Skill – Enhances an ally’s Break Effect and Weakness penetration, making it essential for team synergy.
3. Ultimate – Provides Toughness reduction, but its overall impact is lower than her Talent and Skill.
4. Basic Attack – Least important, offering minor benefits compared to her other abilities.

Major Trace Priority:
1. A4 – Provides the biggest improvement to her overall support capabilities.
2. A2 – Enhances her effectiveness, making it the second-best upgrade.
3. A6 – Offers the smallest impact but is still worth upgrading once the others are maxed.

By following this skill priority, Fugue will be able to maximize her Break Effect utility, ensuring consistent high-damage Weakness Breaks while enhancing her team’s overall performance.

Conclusion

Fugue is a top-tier Break Effect support in Honkai: Star Rail, excelling at enhancing Break-focused teams through Exo Toughness, DEF reduction, and Weakness penetration. Her ability to enable double Breaks makes her an invaluable asset for any team that relies on Weakness Break mechanics.

Her best Light Cone is Long Road Leads Home, which significantly boosts Break Effect and team-wide Break DMG, but alternative options like Resolution Shines As Pearls of Sweat and Solitary Healing also provide solid utility. The Iron Cavalry Against the Scourge relic set, paired with Forge of the Kalpagni Lantern, further enhances her Break capabilities, ensuring maximum damage output from her allies.

When upgrading her abilities, her Talent and Skill should be the top priorities, as they directly impact her Break Effect amplification, while her Ultimate and Basic Attack are lower-priority upgrades.

With the right build, relics, and team composition, Fugue becomes a game-changing support, elevating Break-based teams to their fullest potential. If you’re focusing on Weakness Break strategies, Fugue is an essential character to invest in.
