Luka
Belobog's Underworld Boxing Champion
Luka is a 4★ Physical Nihility fighter who deals single-target damage through Bleed. His Skill inflicts a Bleed based on the enemy's Max HP, his Enhanced Basic ATK makes it deal damage again on the spot, and his Ultimate makes the target take 20% more DMG from the whole team. Easy to build since he ignores CRIT, he is now a niche pick, mostly for DoT and Physical teams.

Main stats
Substat priority
Stat targets
- Effect Hit Rate: 67%
- SPD: 134 / 143 (recommended) / 160
- ATK: 2,400–2,800+
- Break Effect: 0–120% depending on your team
Talent priority
Major Trace priority: Cycle Braking (A4) > Kinetic Overload (A2) > Crush Fighting Will (A6). Use a Break Effect rope (Prydwen) when your team relies on Physical Weakness Breaks, an ATK% rope (Game8) otherwise.
Recommended teams
DoT with Kafka
Game8's best team: Kafka detonates his huge Bleeds (and Break Bleeds) over and over, Ruan Mei boosts Break and delays enemies, and Huohuo heals and adds ATK and Energy.
Physical Break
Prydwen's synergies: Boothill breaks and inflicts massive Break Bleeds that Luka's Enhanced Basic ATK detonates, Fugue makes Breaks easier, and Gallagher heals Break teams.
Mono-Physical
Game8's accessible option: Silver Wolf implants Physical Weakness and shreds DEF so Luka can Break enemies and Bleed them twice.
How to play
How he works
- Lacerating Fist (Skill). Deals 120% of his ATK and has a 100% base chance to inflict Bleed for 3 turns: the enemy takes 24% of its Max HP as Physical DoT at the start of each turn, capped at 338% of Luka's ATK. His A2 also dispels 1 buff from the target.
- Flying Sparks (Talent). He gains 1 stack of Fighting Will after each Basic ATK or Skill (up to 4) and starts combat with 1. With 2 stacks, his Basic ATK becomes Sky-Shatter Fist: 3 hits of Direct Punch, then a Rising Uppercut that makes the target's Bleed immediately deal 85% of its original DMG. His A6 gives each Direct Punch hit a 50% fixed chance of an extra hit, and his A4 grants 3 Energy per stack gained.
- Coup de Grâce (Ultimate, 130 Energy). Grants 2 stacks of Fighting Will, has a 100% base chance to make the target take 20% more DMG for 3 turns, then deals 330% of his ATK.
Rotation
- Use his Technique: he enters combat by Bleeding a random enemy and gains an extra stack of Fighting Will.
- Use his Skill to apply or refresh Bleed (it lasts 3 turns).
- Use Sky-Shatter Fist whenever you have 2 stacks to detonate the Bleed.
- His Ultimate gives 2 stacks straight away, so follow it with Sky-Shatter Fist on the debuffed target.
Tips
- Against bosses, his Bleed quickly hits its ATK-based cap: ATK is what raises his damage.
- A Physical Weakness Break adds a second Bleed, which his Uppercut and Kafka can also detonate.
- Reach 67% Effect Hit Rate so his Bleed and his Ultimate's debuff land reliably.
- He is purely single-target: keep him for Memory of Chaos and Apocalyptic Shadow bosses rather than Pure Fiction.
Strengths
- Solid single-target damage against high-HP enemies
- Detonates his own Bleeds to frontload damage
- 20% DMG taken debuff that helps the whole team
- Dispels enemy buffs with his Skill
- Easy to build: he doesn't need CRIT stats, and his Eidolons are easy to get
Weaknesses
- No AoE at all
- His Skill's Bleed is capped by his ATK
- Far behind modern damage dealers in 4.5 endgame
