Should you pull Luka?

Luka is a free 4-star DoT sub-DPS, ideal if you already own Kafka/Black Swan or want a cheap Bleed applicator. If you don't run DoT teams you can safely skip him, as the current meta offers stronger picks.

Pros
  • Free 4-star, easy to obtain and invest in
  • Consistent Bleed application with good SP economy
  • Ultimate adds a vulnerability debuff that helps the whole team
Cons
  • Reliant on a dedicated DoT team (Kafka/Black Swan)
  • Weak in Pure Fiction and multi-target content
  • Multi-Skill rotation is a bit button-heavy
  • Gradually outclassed by newer DPS units
How to play

Open with his Ultimate to enter the enhanced state, then Skill each turn to stack Bleed and fire the upgraded hit while keeping Fighting Will topped up. Keeping Bleed on the target at all times is the top priority.

Stat targets

Aim for ~67% Effect Hit Rate to lock in Bleed, SPD 134+ (ideally ~160 with buffs), and 3000+ ATK in combat. CRIT is largely unnecessary since his damage comes from ATK-scaling DoT.

Best teams for Luka

His best home is a DoT hypercarry around Kafka/Black Swan plus a healer. A budget version pairs Silver Wolf's DEF shred with Gallagher; newer players can slot Sampo/Natasha instead.

Eidolons
How far to invest, which milestones matter

E0 (E2 là mốc rất mạnh, E6 chỉ cho fan cứng) — E0 is perfectly playable in a DoT team. E2 is the standout breakpoint, self-generating Fighting Will and boosting damage noticeably. E6 is very strong but reserved for dedicated fans.

E1
Fighting Endlessly★★★☆☆
When Luka takes action, if the target enemy is Bleeding, increases DMG dealt by Luka by 15% for 2 turn(s).
Grants a 15% DMG increase for 2 turns when the target is Bleeding, a conditional but easy-to-trigger buff since Luka applies Bleed often.
E2
The Enemy is Weak, I am Strong★★☆☆☆
If the Skill hits an enemy target with Physical Weakness, gain 1 stack(s) of Fighting Will.
Only grants 1 extra Fighting Will stack when Skill hits a Physical-Weak enemy, a minor and enemy-dependent effect.
E3
Born for the Ring★★☆☆☆
Skill Lv. +2, up to a maximum of Lv. 15. Talent Lv. +2, up to a maximum of Lv. 15.
Only levels up Skill and Talent, adding no new effect, so the power gain is minimal.
E4
Never Turning Back★★★☆☆
For every stack of Fighting Will obtained, increases ATK by 5%, stacking up to 4 time(s).
Each Fighting Will stack adds 5% ATK, up to 20% ATK at 4 stacks, a solid and fairly easy-to-maintain damage buff.
E5
The Spirit of Wildfire★★☆☆☆
Ultimate Lv. +2, up to a maximum of Lv. 15. Basic ATK Lv. +1, up to a maximum of Lv. 10.
Only levels up Ultimate and Basic ATK, adding no new effect, so the impact is low.
E6
A Champion's Applause★★★★★
After the Enhanced Basic ATK's "Rising Uppercut" hits a Bleeding enemy target, the Bleed status will immediately deal DMG 1 time equal to 8% of the original DMG for every hit of Direct Punch already unleashed during the current Enhanced Basic ATK.
When the Enhanced Basic ATK's Rising Uppercut hits a Bleeding enemy, it triggers extra Bleed DMG scaling with the number of Direct Punch hits already dealt, creating a major damage spike and reshaping the combo's finisher.

Skills & Traces
What to level first — tap each skill for details
Skill Leveling Priority
Skill ★★★★★ The Skill deals 150% ATK direct DMG and applies Bleed DoT worth up to 422% ATK over 3 turns, making it Luka's main damage source.
Ultimate ★★★★☆ The Ultimate deals a large 396% ATK hit and increases the target's DMG taken by 24% for 3 turns, amplifying all subsequent damage on that target.
Basic ATK ★★★☆☆ With 2+ Fighting Will stacks, Direct Punch upgrades into the multi-hit Sky-Shatter Fist (about 196% ATK total), the most frequently used attack in Luka's rotation, so it still needs leveling despite ranking behind Skill and Ultimate.
Talent ★★☆☆☆ The Talent only accumulates Fighting Will and triggers the enhanced Basic ATK mechanic without dealing scaled damage of its own, making it the lowest leveling priority of the four.
Trace priority: A6 > A4 > A2 Eidolon priority: E6 > E1 = E4 > E2 > E3 = E5

How to read this build page

Every character build page has these parts: recommended Light Cone/Relic sets and stat table, a Trace/skill leveling order, Eidolon milestones worth considering, and a reference SPD threshold. Read them in that order — gear tells you "what to use", Traces tell you "what to level first", Eidolon tells you "is it worth pulling dupes", SPD tells you "how fast you need to be to keep the rotation on time". The section below explains how to read each part and applies the same way to every character on the site — check the exact numbers in the table above this section, since community sources sometimes differ by a few points.

Why the Light Cone and Relic picks make sense

Most characters have a "signature" Light Cone built for their exact role, plus a few cheaper substitutes from the standard banner or easy-to-get 3-4★ cones. Missing the signature isn't a dead end — most characters keep most of their power with a well-matched substitute, typically losing somewhere between a few percent and roughly a fifth of total damage depending on the setup, per most public comparisons.

  • Relic sets (2pc+2pc or 4pc) are picked for the set effect that fits that character's role (single-target DPS, AoE, shield/healing support, Break damage, and so on).
  • Main stats per slot (Body/Feet/Sphere/Rope) and substats follow a priority that changes by role: DPS roles usually chase CRIT Rate/CRIT DMG before ATK%; Break-focused roles prioritize Break Effect; support/healing roles often value Effect Hit/RES or Outgoing Healing over pure CRIT.

These weights differ per character and can shift slightly between ranking sources — follow the exact priority table above rather than applying one formula to every role.

Trace/skill leveling order by role (a general guideline, not a fixed rule)

There's no single order that's correct for every character, and community sources sometimes disagree depending on the team the character is used in — but the general pattern by role is:

  • DPS: level whichever skill (Skill or Ultimate) carries most of the damage for that character first, with Basic ATK usually last if it isn't the main damage source.
  • Support/Buffer: prioritize Traces that boost buff strength or the skill that applies the effect over Basic ATK, since this role's value comes from lifting the team rather than personal damage.
  • Healer/Shielder: prioritize the main healing or shield skill first, since that is the reason the team runs this character.
  • Break/CC: prioritize whichever skill contributes the most Toughness Damage, since the Break/Weakness Break window is where the team dumps damage.

Major Traces unlock at fixed ascension levels in-game, not by choice — but which one to level first (when resources are limited) should follow the role priority above. Since the exact order can differ between ranking sources, check the specific recommendation in the table above for this character.

Eidolons: how far E0 gets you, and which milestone is worth considering

General rule: most characters at E0 (no duplicates) already handle most content, even 5-star characters. Eidolons are a duplicate-fueled upgrade system — higher levels cost more resources for a smaller power gain, and the actual gain varies a lot per character (some barely change role at E0, others shift how they're played at a specific level). The milestones most often cited by the community tend to sit at E1, E2, or E6 depending on the character — but none of these are required to clear the game's content. Check the Eidolon section in the table above for this character's specific milestone and gain; if sources disagree on how to rate a milestone, trust the in-game effect description over a pre-set percentage number.

How to think about SPD breakpoints

SPD (Speed) controls how often a character acts in the turn order — higher SPD means denser actions, and for some roles (especially support/healing that need to buff or heal before the team gets hit) hitting the right SPD "breakpoint" matters more than the raw SPD number. Values like 101 or 134 SPD are often cited as community-common breakpoints (letting a character act again before or after a specific point in certain team setups) — this is crowd-verified action-gauge math, not an official fixed number the game states for every situation. The right breakpoint also depends on the team and allies' SPD, so treat the SPD suggestion in the table above as a starting point to adjust from, not a mandatory target.
