OptionWhy choose it?Conditions and availability
Guide’s reference choiceKafka detonates Luka's Bleed, Ruan Mei improves Break ownership and team damage, and Huohuo sustains while feeding ATK and Energy.

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.
