Best Gallagher Build & Teams In Honkai: Star Rail

Gallagher is a flexible 4-star Fire Abundance character in Honkai Star Rail, offering a mix of healing and support utility. If you’re planning to use Gallagher effectively, this guide covers his best builds, optimal team compositions, recommended Relics, Light Cones, and essential materials to maximize his sustain and healing potential.

Gallagher Character Overview

Gallagher is still being evaluated in Honkai Star Rail following his introduction in the 2.0 update, but his unique healing mechanics make him a strong contender for many teams. Unlike traditional healers, Gallagher restores HP to allies when they attack enemies afflicted with his Besotted debuff, making him a valuable asset in teams that rely on consistent debuffs or sustain.

At max level, his base stats include:
• HP: 1305
• ATK: 529
• DEF: 441
• SPD: 98

If you need a versatile healer who synergizes well with debuff-heavy teams, Gallagher is definitely worth considering.

Best Relics and Light Cones for Gallagher

For the best performance, Thief of Shooting Meteor is the ideal relic set for Gallagher, providing a substantial Break Effect boost along with Energy restoration to keep his healing and debuffs consistent. To further enhance his Break Effect potential, the Talia: Kingdom of Banditry planar ornament set is the best choice, helping him reach the optimal 150% Break Effect threshold.

When it comes to Light Cones, Night of Fright is the best option, offering Energy Regeneration and additional healing to the lowest HP ally, making Gallagher even more reliable as a sustain unit. For free-to-play players, What Is Real is a strong alternative, as it boosts his Break Effect, ensuring he can maintain his healing output while increasing the effectiveness of his debuffs.

Optimal Builds and Teams for Gallagher

To fully utilize Gallagher’s potential, focus on maximizing his Break Effect, which directly enhances his healing capabilities. The ideal build should aim for at least 150% Break Effect and 145 SPD, allowing him to take turns frequently while benefiting from his relic bonuses.

Gallagher is highly flexible and fits into various team compositions, but he excels when paired with DPS units that thrive on debuffed enemies, such as Acheron and Dr. Ratio. For additional synergy, Ruan Mei is an excellent support option, as she can further boost Gallagher’s Break Effect, enhancing both his healing output and debuff application.

Gallagher Ascension and Trace Materials

To fully ascend Gallagher, you’ll need resources such as Dream Collection Components, Dream Flow Valve, Making Engines, and Raging Heart. Additionally, unlocking and upgrading his Traces will require Alien Tree Seed, Nourishing Honey, Past Evils of the Borehole Planet Disaster, and Tracks of Destiny. Gathering these materials will maximize Gallagher’s healing potential and enhance his overall performance in battle.

Conclusion

Gallagher is a solid addition to any Honkai Star Rail team, offering a mix of healing and debuff synergy that makes him highly valuable in both sustain and Break Effect-focused compositions. His ability to restore HP while weakening enemies ensures that he remains relevant in a variety of team setups. Whether you’re running him alongside debuff-heavy allies or simply need a reliable healer, optimizing Gallagher’s relics, light cones, and team compositions will help you unlock his full potential. Investing in his Ascension and Trace upgrades will further enhance his utility, making him a strong pick for any roster.
