Joining the roster of playable characters in the second part of the Penacony world in the version 2.1 update of Honkai: Star Rail, Gallagher is a 4-star Abundance character, which is relatively rare among characters from multiple paths. With his addition, players will have even more options for healing-oriented characters, especially if they are focused on F2P options and aiming to prioritize 4-star characters. However, as with every character, players will need to pay attention to building Gallagher as optimally as possible to gain the most benefits from his abilities. Luckily, being a support character, building him is relatively easier than it is for most DPS characters, as he only needs to focus on certain stats.
