Gallagher is a lie. Honestly, that is the most important thing you need to understand about the scruffy, middle-aged security officer of Penacony’s Bloodhound Family. If you’ve spent any time in the Dreamscape, you’ve probably seen him leaning against a bar, looking like he hasn't slept since the Amber Era began. He’s slovenly. He’s indolent. He’s also one of the most mechanically "broken" 4-star units ever released in Gallagher Honkai Star Rail.
But here is the kicker: Gallagher doesn't actually exist. Not really.
He is a composite, a "fictional" man stitched together by a History Fictionologist from the traits of 52 different members of the Family. When he tells you he is thirteen, he isn't talking about his age in human years. He’s referencing the thirteenth Tarot card—Death. It’s that kind of layered, Enigmata-fueled storytelling that makes him more than just a guy who throws a mean "Special Brew."
Why Gallagher Honkai Star Rail Still Dominates the Meta
You’d think a 4-star healer would have been powercrept by now. We have Lingsha. We have Luocha. We have Huohuo. Yet, in 2026, players are still slotting this "fake" man into their most expensive team comps. Why? Because he isn't just a healer. He is an SP-generating machine that doubles as a Break DMG amplifier.
Most Abundance characters are passive. They sit there and wait for your team to get hit. Gallagher? He wants to fight. His entire kit revolves around the "Besotted" state. When he hits his Ultimate, Champagne Etiquette, he inflicts this debuff on every single enemy. Suddenly, every time your allies hit those enemies, they heal themselves. It turns your DPS into a self-sustaining vampire.
He’s basically a Nihility character wearing an Abundance hat.
The Breakdown of the Kit
- Nectar Blitz (Enhanced Basic): After he ults, he gets a 100% Action Advance. He immediately follows up with a massive hit that lowers the enemy's ATK.
- Besotted (Talent): This is where the magic happens. It increases the Break DMG enemies take. If you’re running a Super Break team with the Trailblazer (Imaginary), Gallagher isn't just keeping you alive—he's helping you delete boss health bars.
- Novel Concoction (A2 Trace): This converts his Break Effect into Outgoing Healing. You build him to break, and he heals more because of it. It’s perfect synergy.
The "True Lie" and the Enigmata
There is a letter you find on the Astral Express after the Penacony arc. It’s a goodbye. Gallagher fulfilled his mission for Mikhail, the Watchmaker, and then he simply... dissolved. Because he was a creation of the Enigmata, once the "lie" was fully revealed and its purpose served, the persona had no more tether to reality.
He calls himself a "loyal hound," and it’s heartbreaking. He spent years waiting for the Nameless to arrive, carrying the guilt of not being able to save Mikhail. Some fans still theorize that the "original" person behind the Gallagher mask is still out there, hiding in the shadows of the Enigmata. But for now, all we have is the memory of a man who loved a bitter drink and a good mystery.

The Best Teams for Him Right Now
If you’re lucky enough to have him at E2 (which adds a cleanse to his skill) or E6 (which boosts his Break Efficiency), he is top-tier.
- The Firefly/Boothill Break Core: He is essentially the best-in-slot sustain for any Break-focused team. He contributes to the toughness bar depletion almost as much as the primary DPS.
- The Acheron Battery: Because his Ultimate and his Enhanced Basic both count as debuffs, he helps Acheron build her "Slashed Dream" stacks faster than almost any other healer.
- The "Perpetual Cycle" with The Dahlia: A newer 2026 meta favorite. The synergy between Gallagher's high energy refund and energy-feeding supports keeps his Ultimate uptime nearly at 100%.
Building Him Without Losing Your Mind
Don't overcomplicate this. You want Speed. You want Break Effect. You want Energy Regeneration.
For his Light Cone, "What is Real?" is the obvious f2p choice, but if you have "Post-Op Conversation" at high refinement, the Energy Regeneration Rate is often better for keeping "Besotted" active. For relics, "Iron Cavalry Against the Scourge" is the modern gold standard, but the classic "Thief of Shooting Meteor" still works if you have godly substats on it.
Just get him to 150% Break Effect to max out his healing bonus. Anything after that is just spicy damage.
Actionable Tips for Your Next Run
- Don't use his Skill unless it’s an emergency. Use his Ult to trigger the team-wide heal through the "Besotted" state.
- Time his Ult correctly. Wait until just after an enemy moves so you can maximize the duration of the ATK reduction debuff.
- Focus on E2. If you’re a new player, aim for at least his second Eidolon. Having a healer who can't cleanse a stun is a recipe for a reset in Memory of Chaos.
Gallagher is a masterpiece of character design because he reflects the core theme of Penacony: the beauty of a well-told lie. He might not be "real" in the story, but the 100,000+ damage he can dish out in a Super Break window is very, very real.
Stop benching him because he's a 4-star. Give the man his drink, build his Break Effect, and watch him outclass your limited 5-stars.
Next Steps for Your Build:
Check your inventory for a 5-star Energy Regeneration Link Rope. If it has Speed and Break Effect substats, lock it immediately. Then, head over to the Clockie Statue or the latest 2026 events to see if there's a free Gallagher selector available—getting those Eidolons is the single biggest upgrade you can give your account.
