Skill Priorities

Recommended Light Cones

  1. In the Name of the World (5⭐)
  2. Incessant Rain (5⭐)
  3. Good Night and Sleep Well (4⭐)
  4. Solitary Healing (5⭐)
  5. Eyes of the Prey (4⭐)

1) In the Name of the World

Increases the wearer's DMG to debuffed enemies by 24~40%. When the wearer uses their Skill, the Effect Hit Rate for this attack increases by 18~30%, and ATK increases by 24~40%.
Notes: The first effect increases Luka's overall damage (if the enemy has a debuff). And although the second effect only increases his Skill's Effect Hit Rate and ATK, it's still a great 5-Star LC.

2) Incessant Rain

Increases the wearer's Effect Hit Rate by 24~40%. When the wearer deals DMG to an enemy that currently has 3 or more debuffs, increases the wearer's CRIT Rate by 12~20%. After the wearer uses their Basic ATK, Skill, or Ultimate, there is a 100% base chance to implant Aether Code on a random hit target that does not yet have it. Targets with Aether Code receive 12~20% increased DMG for 1 turn.
Notes: Although Luka doesn't really benefit from the Crit Rate bonus, the LC can help Luka stack his Effect Hit Rate so he can focus on other stats for Relics.

3) Good Night and Sleep Well

For every debuff the target enemy has, the DMG dealt by the wearer increases by 12~24%, stacking up to 3 time(s). This effect also applies to DoT.
Notes: Best at Superimposition 5 for Main DPS Luka as there is no support ability on this LC.

4) Solitary Healing

Increases the wearer's Break Effect by 20~40%. When the wearer uses their Ultimate, increases DoT dealt by the wearer by 24~48%, lasting for 2 turn(s). When a target enemy suffering from DoT imposed by the wearer is defeated, regenerates 4~6 Energy for the wearer.

5) Eyes of the Prey

Increases the wearer's Effect Hit Rate by 20~40% and increases DoT by 24~48%.
Notes: Another LC that helps Luka with his Effect Hit Rate while also increasing his Bleed damage.

Team Recommendations

1) Mono Physical Team

A team where Physical character such as Carla/Sushang/Argenti is the main DPS while Luka can be the Sub-DPS, inflicting Bleed and increasing damage received by an enemy. Silver Wolf is the key member that can't be replaced as she needs to add a Physical Weakness on enemies that don't have it. But if they have Physical Weakness, using Ruan Mei is better.

Clara / Sushang: Main DPS
Luka: Sub-DPS
Silver Wolf / Ruan Mei: Buffer / Debuffer
Natasha: Healer

2) DoT Team

A lot of DoT damages can be done with the selected 3 Nihility characters. Each 3 of them can apply status effect to enemies, with Luka and Sampo (as Sub-DPS) using their respective Ultimates to increase damage taken by the enemies, and Kafka (as Main DPS) multiplying the damage output from all possible DoT effects.

Kafka: Main DoT
Luka: DoT 2
Sampo / Guinaifen / Black Swan: DoT 3
Luocha (Any other healer or shielder): Healer / Shielder
