Gallagher is a security officer for the Bloodhound Family and a skilled bartender in Honkai: Star Rail. When he's not mixing drinks, Gallagher supports his team with his fighting skills.

To fully understand how this bartender works, here is the best Gallagher build in Honkai: Star Rail.

Gallagher is a four-star support in Honkai, who made his debut on planet Penacony. He is a fire unit that follows the path of Abundance, which means that he excels at healing and keeping his team alive. In addition to his massive healing, Gallagher also specializes in debuffing opponents by increasing their Break Effect chance. He is one of the best four-star units in Honkai, and to get the most out of his kit, you should equip him with the right Light Cones, Relic, and Planar Ornaments sets, and level up his Traces.

Light Cones are character weapons and are an essential part of any build. As a follower of Harmony, Gallagher can only be equipped with Harmony Light Cones and he has a ton of great options for both free-to-play players and light spenders.
