When you play Honkai: Star Rail and when you get to the late game content you will realize how important it is to have an enforcer in your team. Due to the turn-based nature of combat, it's nearly impossible to defeat boss enemies without them getting a few turns and doing tons of damage to your team.

Honkai Star Rail: Best Supporting Characters, Ranked

From protection to damage boost, here are the best support characters to elevate your gameplay in Honkai: Star Rail.

If you want to stand a chance against these enemies, you need to get a screen or a healer like Gallagher in your party. Gallagher is a four-star Fire unit who follows the path of abundance, and he can be quite phenomenal on some teams.

Updated on January 4, 2025 by Sanyam Jain: Gallagher didn't have many choices of Relics and Light Cones when he was first released, but the developers' push into the Break-based meta changed that. This guide has been updated with all the new options you have for him now.

Gallagher doesn't have a signature that fits him perfectly for now, but here are the ones that give you the most value:

Type	Name	Reason for synergy with Gallagher
	Iron cavalry against scourge	This set not only increases Gallagher's Break Effect but also allows him to ignore the enemy's DEF based on how much Break Effect he has. It can be great to do a lot of damage with its buffed basic attack.
Relics	Thief by shooting meteor	You will find that you get the most out of this relic set since it increases its Break Effect by as much as 32 percent. Also, you can get a little extra if you break an enemy's weakness with his attacks. Ideally, you'd want to use other characters to break the enemy's weakness, but this works if some smaller mobs get their weakness broken during your Ultimate.
	Passersby to Wandering Cloud	This is another good set on Gallagher if you want to focus on his healing abilities and a small Skill Point generation. However, you will get more outgoing healing bonus from the Thief set if you don't max out his bonus ability.
	Musketeer of wild wheat	If you can somehow get a decent Crit build on Gallagher along with lots of Break Effect and ATK, his basic attack can deal respectable damage. If you use this build, the damage can be buffed with the Musketeer set.
Flat ornaments	Broken keel	If you use Gallagher alongside a Crit-based DPS, this set works perfectly from then on he already has Effect RES to get the bonus from it.
Flat ornaments	Penacony, Land of Dreams	On the other hand, if you use him alongside another Fire DPS, this set can also give you good value because Energy Regeneration will allow him to gain various enhanced basic attacks.

Gallagher Relic Stat Priority

Fortunately, the best sets you can use on Gallagher are all unlocked fairly early in the game, but you still have to contend with the stats of each relic. That's him one of the few healers that gets more value if you get specific stats:

Type	Capital priority	Sub State Priority
Head	HP	Interrupt Effect > ATK Percentage > SPD
Hands	ATK	Interrupt Effect > ATK Percentage > SPD
Body	Crit / ATK Percent	Interrupt Effect > ATK Percentage > SPD
Feet	SPD	Break Effect > ATK Percentage > HP Percentage
Flat sphere	Fire DMG Bonus / ATK percentage	Break Effect > ATK Percentage > SPD > HP Percentage
Link rope	Pause effect	ATK percentage > SPD > HP percentage

Depending on how patient you want to be with Gallagher's relicsthere are essentially two versions you can choose from:

To build a Crit-based build to benefit from the improved basic attack and ultimate damage.
Goes the easier way and build some ATK, HP and DEF to keep him alive as long as possible.

You can go first main stats mentioned in the table if you are going to build a damage and the other if you go for the normal support build. You also need to build some Crit on your substat for the first build.

Best Gallagher Light Cones

Here are all the choices you have when trying to find a light cone for Gallagher:

Alone fragrance remains true	Lingsha's release gave Gallagher this beautiful cone of light that can give her a 60% break while allowing him to take care of increased damage to enemies for two turns after using his Ultimate. The Iron Cavalry with this cone of light makes Gallagher viable to break enemy toughness.
Echoes of the Coffin	This is the best in slot Light Cone for Gallagher as it gives you some ATK to increase your basic attack DMG at the same time as it giving you a significant energy boost with each Ultimate. You too increase all allies' SPD whenever your Ultimate is used.
Time waits for no one	This is basically the best cone of light that works on most healers in the game. It gives you an outgoing Healing bonus while also dealing extra damage based on the healing done.
What is real?	If you're looking for a F2P-friendly light cone for Gallagher, this is it tailored for him with the Break Effect boost. He can also heal some health every time he uses the basic attack.
Perfect timing	Gallagher already gets an outgoing healing boost from his Break Effect, and this one allowing him to gain even more based on his Effect RES.

Gallagher's kit is pretty straightforward to understand, and you'll easily find a use for him in his team if you're a F2P player. However, his value decreases much more if you have other Abundance characters as the healing from his skill is a target. Thankfully, the high Break Effect makes him good for DoT based teams.

Ideally you would like to upgrade Gallagher's Skill first as the healing gets a huge bonus with the levels. You can then upgrade his talent to get more value from his possessed state. If you plan to build Gallagher as a semi-DPS, you can upgrade his basic attack followed by Ultimate as well.
