Then, uses Rising Uppercut to deal 1 hit, dealing Physical DMG equal to 40% of Luka’s ATK to a single enemy target.

At the start of battle, Luka will possess 1 stack of Fighting Will.

Resolution Shines As Pearls of Sweat is the best 4-star Light Cone for Luka

The best Light Cone for Luka in Honkai Star Rail is Good Night and Sleep Well. This Light Cone bases damage dealt by the wearer on an enemy’s number of debuffs. This effect also applies to DoT, stacking up to three times.

However, if you want a 5-star option, we suggest using In the Name of the World, which can be purchased from the Starlight Exchange Store for 600 Undying Starlight.

In terms of a 4-star option, Resolution Shines As Pearls of Sweat is arguably another great option for Luka. This Light Cone has a chance to Ensnare enemies and also reduce their DEF by 12%. It can be obtained from both the Character as well as Light Cone Event Warp.

2-piece: Increases ATK by 12%
4-piece: For every DoT the target enemy is afflicted with, the wearer will ignore 6% of the target’s DEF when dealing DMG to them. This effect is valid for a max of 3 DoTs.

Firmament Frontline Growth is the best Planar Ornament set for Luka in Honkai Star Rail. This Ornament boosts the wearer’s ATK by 12%, and when the wearer’s SPD is equal to or higher than 135/160, the wearer deals 12%/18% more DMG.

Best Team Comp for Luka in Honkai Star Rail

Luka is a DoT character in Honkai Star Rail. Therefore, his best partners in the game are Kafka, Silver Wolf, and Luocha. In this team, Kafka enables Luka massively, while Silver Wolf debuffs enemies and Luocha provides the heals.

However, you can also choose a team with Luka, Kafka, Ruan Mei, and Huohuo. This setup focuses on Kafka triggering DoTs and Ruan Mei increasing the party’s Break Efficiency.
