Joining the playable character roster in the version 2.1 update of Honkai: Star Rail, Gallagher is a healer character with unique animations. As a 4-star Abundance option, Gallagher is relatively F2P-friendly, especially for those who have yet to find a healer character that meets their needs. However, it is crucial that players focus on upgrading him as much as possible to gain the most benefits from him.
