Best Light Cones
#1
Good Night and Sleep Well (S5)
Strongest damage-focused cone for Luka assuming 3 debuffs are maintained on the enemy. DMG dealt increases by up to 24% per debuff stack (max 3), stacking to 72% bonus. Also applies to DoT, making it near-universally best-in-slot for Luka's DoT playstyle.
#2
Patience Is All You Need (S1)
Strong alternative that does not require 3 debuffs. Increases DMG dealt by 40% and SPD ramps up to 24% over attacks. Also inflicts Erode (a Shock DoT) on enemies, synergizing with other DoT characters. No Bleed interaction but solid damage floor.
#3
Eyes of the Prey (S5)
Grants 40% Effect Hit Rate and 48% DoT DMG bonus. Excellent for ensuring Bleed lands reliably while boosting its damage simultaneously. Used in official damage calculations for Luka builds.
#4
Resolution Shines As Pearls of Sweat (S5)
Applies Ensnare on hit, reducing enemy DEF by 16% for 1 turn. Useful for boosting Luka's own damage and the team's overall output. A solid budget option that requires no special mechanics to activate.
#5
Lies Dance on the Breeze (S1)
Top option for supportive Nihility characters that can reach 170 SPD. Provides 18% SPD passively and can reduce all enemy DEF by 24% via Bamboozle. The SPD requirement is achievable with the cone's own passive included.
Best Relics
Cavern Sets
1
Prisoner in Deep Confinement
Best-in-slot cavern set for Luka's DoT build. The 2-piece gives 12% ATK. The 4-piece causes the wearer to ignore 6% of the target's DEF for each DoT afflicting them, up to 3 DoTs (18% DEF ignore). With Bleed and Break Bleed both active, Luka can exploit this bonus fully for massive DoT damage.
2
Thief of Shooting Meteor
Best-in-slot for Break-focused Luka builds. Increases Break Effect by 16% (2-piece) and an additional 16% (4-piece). When the wearer inflicts Weakness Break, regenerates 3 Energy. Excellent for maximizing Break Bleed damage on Physical Weak enemies.
3
Champion of Streetwise Boxing
Increases Physical DMG by 10% (2-piece). The 4-piece stacks ATK by 5% per attack/being hit, up to 5 times (25% ATK). Synergizes naturally with Luka's aggressive fighting style, though Prisoner typically outperforms this in DoT-heavy scenarios.
Planar Ornament Sets
1
Revelry by the Sea
Best planar set for DoT Luka. Increases ATK by 12%. When ATK reaches 2400 or 3600, increases DoT DMG dealt by 12% or 24% respectively. Requires ATK buffs from teammates to reach the 3600 threshold for the stronger bonus, but this set is his top pick when achievable.
2
Firmament Frontline: Glamoth
Increases ATK by 12%. When SPD is 135 or higher, deals 12% more DMG; at 160 SPD, deals 18% more. Luka can reach the 135 breakpoint relatively easily, making this a strong all-round planar option with excellent raw damage output.
3
Talia: Kingdom of Banditry
Increases Break Effect by 16%. When SPD reaches 145 or higher, grants an extra 20% Break Effect. Excellent for Break-focused Luka builds looking to maximize their Break Bleed and toughness damage output on Physical Weak enemies.
4
Pan-Cosmic Commercial Enterprise
Increases Effect Hit Rate by 10% and ATK by an amount equal to 25% of current EHR (max 25% ATK). Useful if running an EHR-heavy setup, providing simultaneous debuff reliability and damage scaling in one planar set.
Best Teams for Luka
Luka thrives as a supplementary single-target damage dealer. His Bleed DoT, damage amplification Ultimate, and dispel capability from his Skill make him a hybrid support-DPS best paired with DoT enablers like Kafka or Break-focused partners.
01 · DoT Core
Best composition for Luka
Kafka utilizes Luka's Bleed by triggering it over and over, resulting in the strongest version of DoT damage in Physical Weak content. Silver Wolf implants Physical Weakness for consistent Weakness Breaks, enabling massive Break Bleeds. Can be applied to all content.

Eidolons
E
1
Fighting Endlessly
When Luka takes action, if the target enemy is Bleeding, increases DMG dealt by Luka by +15% for 2 turns. Since Luka should always have Bleed on his target, this is effectively a near-permanent damage bonus that requires no extra build investment.
High Pull Value
E
2
The Enemy is Weak, I am Strong
If the Skill hits an enemy target with Physical Weakness, gain 1 stack of Fighting Will. Allows Luka to ramp up his Enhanced Basic ATK faster in Physical Weak content, increasing his total Bleed proc count significantly throughout a fight.
Niche Upgrade
E
3
Born for the Ring
Skill level +2 (max 15). Talent level +2 (max 15). The Skill level increase directly raises both the Bleed DoT damage and the ATK scaling on the hit itself. Talent upgrade boosts the forced Bleed proc percentage from Rising Uppercut.
Solid Upgrade
E
4
Never Turning Back
For every stack of Fighting Will obtained, increases ATK by 5%, stacking up to 4 times (+20% ATK max). Since Luka is constantly gaining and spending Fighting Will stacks, this passively increases his ATK and thus his Bleed DoT cap throughout the fight.
Good Passive
E
5
The Spirit of Wildfire
Ultimate level +2 (max 15). Basic ATK level +1 (max 10). The Ultimate level increase boosts both the direct damage and the DMG taken debuff application, improving team-wide damage amplification uptime.

A Champion's Applause
After Enhanced Basic ATK's Rising Uppercut hits a Bleeding target, the Bleed status immediately deals DMG 1 time equal to 8% of original DMG for every hit of Direct Punch already unleashed. Combined with E1, each small hit now procs Bleed damage independently, drastically increasing total forced Bleed output in a single Enhanced Basic ATK turn.
Massive Upgrade
Major Traces
Kinetic Overload
Ascension 2
When the Skill is used, immediately dispels 1 buff from the enemy target. Makes Luka extremely useful against enemies with persistent self-buffs such as Mara Struck or Searing Prowler, adding a reliable dispel tool to Physical Weak content.
Cycle Braking
Ascension 4
For every stack of Fighting Will obtained, additionally regenerates 3 Energy. Since Luka gains Fighting Will stacks frequently through his Basic ATK, Skill, and Ultimate, this trace dramatically accelerates his Ultimate cycling for consistent DMG amplification uptime.
Crush Fighting Will
Ascension 6
When using Enhanced Basic ATK, every hit Direct Punch deals has a 50% fixed chance to use 1 additional hit. This does not apply to the additional hits generated this way. Luka can hit up to 6 times before Rising Uppercut instead of just 3, massively increasing forced Bleed procs at E6.

Frequently Asked Questions
No. Luka's primary damage output comes from Bleed DoT and Break damage, neither of which scale with CRIT Rate or CRIT DMG. Focus entirely on ATK, Speed, Effect Hit Rate, and Break Effect. This makes him easier and cheaper to build than most DPS characters since you avoid the CRIT stat investment entirely.
Luka's Bleed DoT deals 24% of the enemy's Max HP as Physical damage per turn, but this is capped at 338% of Luka's ATK (at max Skill level). Against high-health enemies this cap is easily hit, meaning stacking ATK raises the cap ceiling and makes his Bleed more effective. Break Bleed from Weakness Breaking the enemy has a separate cap tied to your Break Effect%, which can exceed Luka's Skill Bleed when Break Effect is high enough.
Yes. Luka has a built-in Bleed proc mechanic through his Enhanced Basic ATK's Rising Uppercut, which forces Bleed to deal 85% of its original damage immediately. This makes him self-sufficient at triggering his own DoT without needing Kafka. Kafka is still his best partner because she can trigger Bleed multiple additional times per rotation, but Luka functions well and consistently without her.
Luka excels in Memory of Chaos and Apocalyptic Shadow where single-target damage is most valuable. His Bleed scales with enemy Max HP, making him stronger against high-health bosses. He has very little use in Pure Fiction since he has no AoE skills and cannot contribute to clearing waves of enemies efficiently before the boss phase.
The recommended Speed target is 143, which is generally considered optimal for Luka's rotation efficiency. A secondary breakpoint of 134 is acceptable at lower investment. Reaching 160 SPD unlocks the stronger tier of Firmament Frontline: Glamoth's DMG bonus if using that planar set. The Cycle Braking trace (A4) also makes Energy generation faster at higher Speed since you gain more Fighting Will stacks per cycle.
E1 is the most accessible and impactful eidolon, providing a near-permanent 15% DMG bonus when attacking Bleeding targets at essentially no build cost. E6 dramatically increases his total Bleed proc output by adding additional forced procs on each Direct Punch hit, but requires significant investment. As a 4-star, Luka's eidolons are obtainable through standard pulls over time, making E1 and E2 realistic targets for invested players.
