Best Gallagher Build in Honkai: Star Rail Focuses on Break Effect

Unlike other Abundance characters, Gallagher, who debuted in Honkai: Star Rail Version 2.1, only has a few Light Cones and Relics that work well with him. His kit makes him a very aggressive healer.

To start with, Gallagher is unique in that his healing scales off his Break Effect (after you unlock his Novel Concoction Trace). Most of his healing is going to come from this. Until you unlock Novel Concoction, his Skill offers a paltry flat heal. His Ultimate is also a major source of his healing. After he uses it, he inflicts enemies with the Besotted state. Until you unlock the Bottoms Up Trace (and arguably, even after), he’ll be able to heal allies off his turn when they attack a Besotted enemy. Because of this, certain Abundance Light Cones, as well as Relics, do not play nice with how Gallagher works in Honkai: Star Rail.

Here are the Best Light Cones for Gallagher in Honkai: Star Rail

• Night of Fright
  This is Huohuo’s signature Light Cone and it works very well with Gallagher’s kit. It boosts his Energy Regeneration Rate, as well as restores HP for the ally with the lowest HP percentage when he uses his Ultimate. He can also provide an ATK boost when he heals the party. Because Gallagher is a combination of a support and a healer, much like Huohuo is, it makes sense that he would have a lot of synergy with this Light Cone.
• Time Waits for No One
  Time Waits for No One is a great Light Cone that increases her Outgoing Healing, as well as his Max HP (which can help him to survive on the field). It also helps your party deal more damage, since he can deal a random enemy Fire DMG based on the amount he heals his allies. A pro of Time Waits for No One is that, unlike Night of Fright, it’s always available in the gacha. You can also get it for free from the Starlight Exchange.
• What Is Real?
  Unsurprisingly, due to Gallagher being the motif character for this Light Cone, this one suits his kit perfectly. It increases his Break Effect, as well as restores HP for himself after he uses a Basic Attack. This increases his survivability, as you can heal him without needing to use up SP if he’s the only one with lower HP.
• Post-Op Conversation
  Because Post-Op Conversation offers an Energy Regeneration Rate boost, this is a fairly good Light Cone for Gallagher. He cannot make use of the second effect, which is that his Outgoing Healing from his Ultimate increases. However, you can also consider it a fairly good Light Cone for its stats, as it’s a 4-star.
• Hey, Over Here
  Hey, Over Here increases Gallagher’s Outgoing Healing after he uses his Skill, which can be very useful if you don’t have that much Break Effect on him yet. Another pro is that this Light Cone was free during The Foxian Tale of the Haunted event. This means those who played it should have a Superimposition 5 copy of the Light Cone, making it quite powerful. Conversely, those who missed that event will not have access to this Light Cone.
• Shared Feeling
  Shared Feeling can increase Gallagher’s Outgoing Healing, as well as regenerate Energy for his allies after he uses his Skill. Since his Skill is a good way of getting back his Energy, you’ll probably use it quite a bit. This will improve Gallagher’s utility as a support.

Here are the Best Relics for Gallagher in Honkai: Star Rail

• 4-pc Thief of Shooting Meteor
  This is a fantastic set for Gallagher. Not only does it increase his Break Effect, but he can also regenerate Energy when he inflicts Weakness Break on an enemy. Because of his more aggressive play style compared to other Abundance characters, you’ll probably be able to make use of the 4-piece effect quite often.
• 2-pc Thief of Shooting Meteor, 2-pc Watchmaker, Master of Dream Machinations
  If you do not have a good 4-piece Thief set, you can consider doubling the Break Effect with two Thief Relics and two Watchmakers Relics. Because the more Break Effect he has, the more Outgoing Healing he gains, this isn’t a bad thing at all.
• 2-pc Thief of Shooting Meteor, 2-pc Passerby of Wandering Cloud
  This combines Break Effect with Outgoing Healing, and is best for those who just started the game. This is because focusing on his Break Effect is far better than the paltry 10% you get from Passerby’s 2-pc effect. Once you get better pieces from the other Relics here, you should graduate onto them from Passerby.
• Talia: Kingdom of Banditry
  This offers a 16% Break Effect bonus, as well as an additional 20% if Gallagher has at least 145 SPD. As a support, you’ll naturally want to give him lots of SPD, so he should be able to hit it. You can also use a 2-pc Messenger Traversing Hackerspace set to help him hit that threshold.
• Broken Keel
  Broken Keel is one of the best Planar Ornament Sets you can give to support characters. This is because it increases all allies’ Crit DMG for the meager cost of 30% Effect RES.
• Penacony, Land of the Dreams
  While Sprightly Vonwacq offers the same 5% Energy Regeneration Rate boost, the Penacony Set also allows Fire units on Gallagher’s team to deal more DMG. This is a far better secondary effect than Sprightly Vonwacq’s. Of course, this is only important if you plan on using him with other Fire units. If you don’t plan on doing so, you can always choose to use Sprightly Vonwacq instead.

Honkai: Star Rail is readily available on the PS5, Windows PC, and mobile devices. You can always pull for Gallagher, as he is a 4-star character.
