Best Gallagher teams
Teams that want Gallagher
Fire · Break
Himeko
Himeko follows up whenever an enemy is Broken, which turns the standard-warp Erudition unit into a Break team’s damage dealer at no pull cost.
Physical · Break
Boothill
Fugue implants the Weakness and The Dahlia raises Break efficiency; Gallagher heals and his Besotted adds 12% Break DMG taken.
Lightning · Nihility
Acheron
Black Swan and Luka are both Nihility and both put DoT debuffs on the target, which charge Acheron’s Ultimate. Gallagher is the 4-star sustain.
Fire · Burn
Hook
Guinaifen Burns the target and its neighbours, and Hook’s Talent triggers on any Burn, not only her own. Tingyun buffs Hook, Gallagher heals.
Physical · Break
Sushang
Sword Stance is guaranteed on a Weakness Broken target and her SPD rises whenever an enemy breaks, so the team breaks for her: Ruan Mei raises Break efficiency, Gallagher breaks and heals, Hanya returns Skill Points.
Physical · The Hunt
Sushang
Bronya lets her act again and Silver Wolf implants Physical Weakness, so her Skill reaches a Broken target sooner. Gallagher heals.
Quantum · Break
Xueyi
Xueyi gains Karma from every teammate’s Toughness damage and follows up at 8 stacks. The Harmony Trailblazer raises Break, Yukong’s Basic ATK doubles its Toughness Reduction, Gallagher heals.
Imaginary · The Hunt
Dr. Ratio
Each debuff on the target adds 20% to his follow-up chance: Silver Wolf’s Bugs and Gallagher’s Besotted count. Robin buffs the follow-ups.
Lightning · Nihility
Acheron
Acheron charges her Ultimate off debuffs other characters apply, so the team runs two more Nihility units and a sustain that never needs a Skill Point.
Fire · Break
Firefly
A Break Effect carry with two Harmony units that raise Break damage and Weakness Break efficiency, and a sustain that keeps Break uptime rather than adding damage.
Wind · Follow-up
Feixiao
Feixiao converts ally attacks into her own follow-ups, so the other three slots are a follow-up partner, a Harmony unit that advances her, and a sustain.
Ice · Erudition
The Herta
Two Erudition units feed each other stacks on wide waves, a Harmony unit multiplies the area damage, and a sustain covers the turns spent charging.
Lightning · Damage over time
Kafka
Kafka detonates the stacks Black Swan and a third Nihility unit apply, so every slot but the sustain exists to keep a damage-over-time state on the enemy.
Imaginary · HP scaling
Mydei
Mydei spends his own HP to attack, which turns a healer from a safety net into the thing that keeps the rotation running.
Imaginary · Break
Rappa
Break damage across a whole wave rather than one target, so both Harmony slots go to Break amplification and the sustain adds Break of its own.
Quantum · Erudition
Rin Tohsaka
Rin turns Skill Point traffic into CRIT DMG for whoever spent it, and her joint follow-up needs Archer on the field, so the last two slots are picked for Skill Point economy.
Lightning · The Hunt
Ashveil
Ashveil marks one enemy as the Bait and follows up whenever an ally hits it, which makes a second follow-up character worth a slot on its own.
Quantum · The Hunt
Seele
Seele takes an extra turn on a kill, so the team spends everything on making the first hit land: a Quantum Weakness implant, an action advance, and a shield.
Lightning · Erudition
Jing Yuan
His Lightning-Lord attacks on its own turn and its damage scales with stacks, so the team is built to give him turns rather than multipliers.
Imaginary · Destruction
Dan Heng • Imbibitor Lunae
He spends three Skill Points on one enhanced Basic ATK, which means the other three slots have to generate Skill Points rather than consume them.
Physical · Erudition
Argenti
His 180-energy Ultimate is the whole kit, so every other slot is chosen for how much Energy it returns rather than how much damage it adds.
Imaginary · The Hunt
Dr. Ratio
Dr. Ratio follows up when the target carries enough debuffs, so the team is a follow-up partner, a buffer for it, and a sustain that debuffs on the side.
Quantum · Erudition
Qingque
A 4-star carry whose enhanced Basic ATK eats Skill Points and whose damage is a dice roll. It is the cheapest full team on this page, and the least consistent.
Physical · Break
Boothill
Three Break supports and no sustain for a single-target breaker: Fugue implants the Weakness, Ruan Mei and The Dahlia raise Break efficiency. Run in 0.1% of clears across the four endgame modes in 4.6.
Imaginary · Break
Rappa
Three Break supports and no sustain on a wave-clearing breaker: Fugue implants the Weakness, the Harmony Trailblazer and The Dahlia raise Break damage and efficiency.
Imaginary · Break
Rappa
Fugue implants the Weakness and The Dahlia raises Break efficiency across the wave. Lingsha heals and breaks.
Quantum · Break
Xueyi
Her Ultimate ignores Weakness Type and hits up to 60% harder the more Toughness it removes. Ruan Mei raises Break efficiency, Bronya gives her another action, Fu Xuan takes part of the damage.
Imaginary · Destruction
Dan Heng • Imbibitor Lunae
Hanya’s Burden returns one Skill Point for every two attacks on the marked enemy, the 4-star answer to his three-point Basic ATK. Tingyun adds ATK and Energy, Lynx heals.
Physical · Counter
Yunli
Every hit on Yunli is a Counter and 15 Energy, and Lynx’s Skill pulls attacks onto a Destruction ally. Tingyun adds ATK and Energy, Pela shreds DEF.
