Honkai Star Rail Luka materials guide: Ascension, build, and trace level-up resources

The second phase of Honkai Star Rail 1.2 is right around the corner, and it will feature Luka as the brand-new 4-star unit from the Physical roster. He is a renowned cage fighter capable of unleashing consistent damage output thanks to his Nihility Path. He can employ his martial arts prowess to inflict Physical DoT (Damage over Time), securing a spot as a sub-DPS (Damage Per Second) across multiple team compositions.

That said, many players will likely build Luka to tackle enemies with Physical toughness in the end-game content. This guide will cover everything they need to farm to ascend the upcoming martial artist to max level.

How to best build Luka in Honkai Star Rail

The four-piece Champion of Streetwise Boxing is the ideal Relic to build Luka in Honkai Star Rail. The passive increases his Physical DMG by 10% and his ATK by 5% whenever he unleashes his ATK or takes a hit. The latter effect stacks up to five times, significantly boosting his DMG output.

For Planar Ornament, stick to Pan-Galactic Commercial Enterprise, which you can obtain from Simulated Universe World 5. It increases his Effect Hit Rate by 10%, allowing him to effectively stack up his Physical DoT. In addition, the gear boosts his ATK by an amount equal to 25% of his total Effect Hit Rate, up to a maximum of 25%.

HoYoverse does not provide a limited Light Cone for their 4-star units. However, Luka has a few good, accessible options to choose from in Honkai Star Rail.

The Resolution Shines As Pearls of Sweat is one of his best options for a sub-DPS build, as it has a 60% chance to inflict Ensnare on targets that are not afflicted with it. The effect reduces their DEF by 12% for a turn, allowing the cage fighter and his team to deal increased DMG.
