Recommended build

Light Cone

Lies Dance on the Breeze
Best choice

Lies Dance on the Breeze supplies very high SPD and an extra DEF-reduction debuff, improving Luka's Break timing and team detonation damage.

Relics

Best choice

Prisoner in Deep Confinement gives ATK and DEF ignore based on active DoTs, which Kafka teams maintain for Luka.

When to use it : Use with multiple persistent DoTs for the full DEF ignore.

Planar Ornaments

Best choice

Talia: Kingdom of Banditry gives Luka a large Break Effect package at the speed he already wants for detonation timing.

When to use it : Reach 145 SPD in combat.

Team lineup

Best choice

Kafka detonates Luka's Bleed, Ruan Mei improves Break ownership and team damage, and Huohuo sustains while feeding ATK and Energy.

When to use it : Luka applies Bleed and Ultimate vulnerability before Kafka's detonation turn.

Trace priority

  1. Skill
  2. Basic ATK
  3. Ultimate
  4. Talent

Luka applies HP-scaling Bleed, exposes one enemy with Ultimate and uses enhanced Basics to immediately trigger part of the active Bleed.

How to play it

  1. 1Use Skill to apply Bleed to the priority target.
  2. 2Cast Ultimate before the team's detonation window to apply vulnerability.
  3. 3Spend Fighting Will on enhanced Basic after Bleed is active, then let Kafka detonate the remaining DoTs.

Sources and methodology

Editorial recommendations are written from released game data, then cross-checked against specialist calculations. They are not copied from a single tier list.

Review method

The audit measures Bleed application, enhanced Basic detonation, Physical Break ownership and Kafka timing. Break and DoT targets are kept ahead of CRIT stats.

E0 Physical DoT and Break build. The 145-SPD target belongs to Talia; do not claim it through temporary action advance.
