Release2.1
Gallagher is a Fire Abundance healer and the best 4★ sustain in the game. His Ultimate inflicts Besotted on all enemies, which makes them take more Break DMG and heals every ally who attacks them, and his Break Effect boosts his healing. He shines in Break and Super Break teams, and his quick debuffs also help debuff-hungry damage dealers.

Guide
How to play
How he works
- Besotted (Ultimate, 110 Energy). Applied to all enemies for 2 turns: they take more Break DMG, and every ally who attacks them recovers HP. His A4 then advances his own action by 100%.
- Nectar Blitz. The Ultimate enhances his next Basic ATK, which lowers the target's ATK; thanks to his A6, its healing also applies to the whole team.
- Skill. A direct heal for emergencies.
- Break Effect → healing. His A2 converts 50% of his Break Effect into Outgoing Healing (up to +75% at 150% Break Effect).
Rotation
- Open with his Technique to inflict Besotted as the fight starts.
- Ultimate → instant turn (A4) → Nectar Blitz, then Basic ATKs to generate Skill Points.
- Keep Besotted up and only use his Skill when someone is in danger.
Tips
- SPD is his most important stat: the faster he cycles, the better his Besotted uptime.
- He is very SP-positive, which suits SP-hungry teammates.
- Fast enemies can shake off Besotted — keep an eye on its duration (his E4 adds a turn).
- Besotted and Nectar Blitz give Acheron two debuffs in quick succession.
Strengths
- Best 4★ healer, with strong and consistent healing
- Huge Toughness damage and a Break DMG taken debuff
- Very SP-positive
- Deceptively fast thanks to his A4 advance
- Scales very well with Eidolons
Weaknesses
- His passive healing relies on a debuff that fast enemies can shake off
- Outclassed by premium sustains outside Break teams
Notable dupes · Eidolon
E1
Solid upgrade
20 Energy at the start of battle and +50% Effect RES.
E2
Solid upgrade
His Skill also cleanses 1 debuff from the target and gives them +30% Effect RES for 2 turns: handy against debuff-heavy enemies.
E4
Big upgrade
Besotted lasts 1 more turn, which greatly improves its uptime.
E6
Solid upgrade
+20% Break Effect and Weakness Break Efficiency. As a 4★, E6 is realistic, and Prydwen rates him one tier higher with all his Eidolons (T1.5 instead of T2).
