Optimal Light Cones and Relics

The prime Light Cone for Luka in Honkai Star Rail is In the Name of the World. It amplifies DMG on debuffed enemies by 24%-40%. Additionally, its skill usage increases Effect Hit Rate by 18%-30% and ATK by 24%-40%.


This Light Cone is easily accessible from the Starlight shop at 600 Undying Starlight. For an alternate 5-star choice, Incessant Rain, Silver Wolf’s best-in-slot Light Cone, is viable. However, this Light Cone is solely attainable through limited banners.

As a Physical character, Luka thrives with the Champion of Streetwise Boxing Relic set:

  • 2-piece bonus: Enhances Physical DMG by 10%.
  • 4-piece bonus: Boosts ATK by 5% after attacking or being hit, stackable up to 5 times.

The Pan-Galactic Commerical Enterprise Planar Ornament set maximizes Luka’s potential, enhancing Effect Hit Rate and ATK.


Crafting an Optimal Team for Luka

Luka’s DoT specialization calls for strategic alliances:

  • Kafka, Sampo, and Luocha: Kafka enhances Luka’s capabilities, Sampo augments DoT effects, and Luocha offers healing.

For a Physical DPS focus, consider a team with Natasha, Silver Wolf, and Sushang. Silver Wolf’s debuffs accentuate Luka’s impact.

Both team compositions boast exceptional strength, with your choice hinging on content and character availability.
