Honkai: Star Rail character guide

Gallagher Best Build

A Break-oriented healer who applies Besotted and heals allies when they attack marked enemies.

Gallagher build overview

Gallagher is a Fire Abundance character commonly used for sustain, break, debuff. The recommended build focuses on the part of the kit used most often while keeping the team rotation reliable.

Use Messenger + Passerby as the primary Relic set and Forge of the Kalpagni Lantern as the Planar Ornament. Recommended main stats are Outgoing Healing, SPD, HP% / DEF%, Energy Regen. Secure important Speed, Effect Hit Rate or Break Effect requirements first when the kit needs them, then improve the character's main scaling and offensive or defensive substats.

Light Cones and alternatives

What Is Real? is the premium Light Cone because its passive is designed around Gallagher's core mechanics. The build remains functional without it. Multiplication and Post-Op Conversation provide practical alternatives when their passives stay active in the selected team. Strong Relic stats can be more valuable than forcing a theoretical equipment upgrade with poor synergy.

Recommended teams

  • Premium team: Firefly, Fugue, Ruan Mei, Gallagher. This formation keeps Gallagher in the core role while covering damage amplification, turn economy and sustain.
  • Alternative team: Acheron, Jiaoqiu, Pela, Gallagher. This formation keeps Gallagher in the core role while covering damage amplification, turn economy and sustain.
  • Accessible team: Boothill, Trailblazer, Ruan Mei, Gallagher. This formation keeps Gallagher in the core role while covering damage amplification, turn economy and sustain.

When replacing a teammate, preserve the same job rather than copying rarity alone: keep the required buffer or debuffer, maintain Skill Point economy and add a sustain suited to the encounter.

Trace priority

  • Lower priority: Corkage Fee
  • High priority: Special Brew
  • Highest priority: Champagne Etiquette
  • High priority: Tipsy Tussle
  • Lower priority: Artisan Elixir

Raise the ability that defines Gallagher's main role first. Lower-impact abilities can remain below maximum until the character, Light Cone and important teammates have received their guaranteed upgrades.

Investment advice

Start with character and Light Cone levels, major Traces and correct main stats before extended Relic farming. An E0 build with a suitable alternative Light Cone is intended to be complete. Signature equipment and Eidolons are premium upgrades and should be compared with improvements to the rest of the account.

Frequently asked questions

Does Gallagher need the signature Light Cone?

No. What Is Real? is the premium recommendation, but the listed alternatives preserve the core playstyle.

What is the most important build rule?

Meet the character's functional stat requirements first, then improve damage or utility without breaking team order and resource management.
