Let me be real with you—when I first saw this scruffy, ponytailed bartender stroll into the Express, I figured he’d just be another 4-star benchwarmer. Then I actually built him. Now I’m in 2026, still watching my DPS characters mow down waves of enemies while Gallagher casually maintains everyone’s HP and throws out debuffs like he’s slipping extra shots into a cocktail. Who knew the guy who mixes drinks could mix such a mean support kit?
Gallagher hails from the Abundance Path but acts like he forgot to read the healer manual. His whole shtick? Slap a debuff called Besotted on enemies, and any ally who attacks those poor, lovestruck foes gets healed. This means you rarely waste Skill Points on emergency heals—your team keeps dealing damage, and the healing just happens. It’s the "best defense is a good offense" philosophy, but with a band-aid dispenser built into every punch. If you finished his Ascension and left him at level 40 because you weren’t sure what to do with him, it’s time for a glow-up. Let’s break down how to turn this Fire-wielding bartender into your favorite sustain unit.
Best Light Cones: Give Him the Glowstick of Doom
Light Cones for Gallagher follow a simple rule: if it boosts healing or Break Effect, grab it. If you somehow snagged Night of Fright (Huohuo’s 5-star signature), congratulations—you own the best Abundance Light Cone in the game, and it’s practically glued to Gallagher in my account. That baby gives 12% Energy Regeneration Rate and a team-wide heal whenever an ally uses their Ultimate. Oh, and after you heal someone? They get an ATK boost that stacks up to 5 times. So Gallagher turns into a part-time buffer while he’s at it. More Energy means more frequent Ultimates, which means Besotted never drops, which means nobody dies. Simple, right?
But what if you’re like me two years ago, staring sadly at your 4-star collection? Don’t panic. What Is Real is the secret sauce. This 4-star Light Cone pumps Gallagher’s Break Effect by a massive 24%, and since his healing scales directly off Break Effect, you’re already cooking. On top of that, every Basic Attack restores HP—sure, the numbers look modest, but it triggers the whole Besotted engine without costing a single Skill Point. When I first slapped What Is Real on him, I suddenly had extra room to invest in SPD and Energy Regen without crying over my relic RNG. Other solid 4-star alternatives include Post-Op Conversation for more Energy, Shared Feeling for party-wide heal boosts, or Quid Pro Quo if you like playing battery for your carries. But honestly? Just farm What Is Real and call it a day.
Relics & Ornaments: Stacking Break Effect Like a Hoarder
Here’s where things get funny. You look at a healer and think, “I need HP, Outgoing Healing, maybe some Effect RES.” Nope. Gallagher’s healing scales with Break Effect. That means you want him to shatter enemy toughness bars like it’s his day job—and the more Break Effect you pile on, the bigger his green numbers get.
Thief of Shooting Meteor is my go-to Relic set. The 2-piece bonus gives 16% Break Effect, and the 4-piece adds another 16% plus 3 Energy whenever you inflict Weakness Break. Do I proc the 4-piece often? Nah. But that 32% total Break Effect is a drug I can’t quit. Since Gallagher’s Fire element has a handy habit of breaking enemies, you’ll sneak in that extra Energy more often than you’d expect.
For Ornaments, your best friend is Talia: Kingdom of Banditry. Another 16% Break Effect from the 2-piece, and if you push Gallagher’s SPD to 145 or higher (which you absolutely should), you unlock an extra 20% Break Effect. At that point, your healing numbers start looking like a 5-star’s. If you’ve been ignoring Speed boots on healers, let this be your wake-up call.
When farming, scream these substats into the void and pray: Break Effect > SPD > Energy Regeneration Rate > Outgoing Healing. A sprinkle of HP%, Effect RES, or DEF won’t hurt, but treating them as main goals is like ordering a salad at a barbecue—you’re missing the point.
Team Comps: He Slots Anywhere There’s Violence
Gallagher’s flexibility is honestly hilarious. I’ve jammed him into hypercarry teams, DoT teams, follow-up attack teams—if the team constantly smacks enemies, he works. The key is his Besotted debuff: it counts as a negative status, so characters like Acheron absolutely adore him. She stacks her Ultimate faster while Gallagher quietly keeps everyone alive, all without stealing Skill Points. It’s a match made in space-heaven.
That said, please remember he’s a 4-star. His raw healing output sometimes trails behind a fully kitted Luocha or Huohuo, especially in high-tier Memory of Chaos. My solution? Bring a shielder. Trailblazer (Fire) is stupidly good here—pseudo-preservation with a taunt, and both of them can break Fire-weak enemies into next week. Together, they create a cozy little fortress of destruction.
If you hate shields and live on the edge, swap in Ruan Mei. Her A2 trace gives the whole team 20% Break Effect, which gives Gallagher’s healing a lovely bump (again, because he scales with Break Effect—sense a pattern?). She also speeds up breaking, which means Besotted gets applied faster, which means more healing from all the aggressive bonking. It’s a feedback loop of violence and recovery. I’ve run Gallagher + Ruan Mei + Acheron + Pela, and the enemy never knew what hit them. Probably because they died too fast to read the debuff list.
Here’s a quick cheat sheet for team templates:
| Core Setup | Flex Slot 1 | Flex Slot 2 | Why It Works |
|---|---|---|---|
| Gallagher + DPS | Shielder (Fire MC) | Harmony (Ruan Mei, Bronya) | Maximum safety and Break shenanigans |
| Gallagher + Acheron | Nihility debuffer (Pela) | Nihility/Harmony (Silver Wolf/Sparkle) | Fast Ultimate cycles, constant debuffs |
| Gallagher + DoT team | Kafka | Black Swan | DoTs tick while healed attacks keep you topped off |
| Gallagher + Follow-up | Topaz | Dr. Ratio | FUA triggers additional Besotted heals, Skill Point heaven |
Skill Priority: Ult First, Everything Else Later
Don’t be the player who levels Basic Attack to 10 and wonders why Gallagher feels weak. His ability priority is a straight line: Ultimate > Skill > Talent > Basic Attack.
Gallagher’s Ultimate applies Besotted to all enemies and gives him an enhanced Basic Attack (which hits AoE and heals the team). That’s his bread and butter. Max it yesterday. Next, his Skill is an emergency single-target heal plus a tiny cleanse—useful when a character eats a big hit before Besotted can trigger. After that, his Talent boosts all allies’ Break Effect against Besotted enemies, so it indirectly ramps both damage and healing. The Basic Attack? Eh. Upgrade it only if you’re bored and have an excess of mats. I’m pretty sure mine is still at level 2, and nobody has died on my watch.
In 2026, Gallagher remains one of the most fun 4-stars in the game—not because he’s the absolute strongest healer, but because he makes combat feel so fluid. He turns every team into a self-sustaining blender. Just remember: Break Effect, Speed, and a willingness to smack enemies before they smack you. Give him a good Light Cone, some snazzy Relics, and let the bartender work his weird, aggressive magic. Cheers! 🍹✨
