What’s the best Honkai Star Rail Luka build?

So far, we’ve only been introduced to Luka through his splash art and a brief appearance in a trailer, but we do know that he’s a four-star character who deals physical damage and walks the path of The Nihility. Characters from this path like Honkai Star Rail’s Sampo and Honkai Star Rail’s Welt excel at applying debuffs and dealing DoT, and we know from the version 1.2 trailer that Luka can inflict bleed on enemies.

What are the best Honkai Star Rail Luka light cones? 

Every Honkai Star Rail character has at least one light cone made specifically to compliment their abilities and Luka’s signature light cone is Resolution Shines As Pearls of Sweat. It’s a four-star light cone for the path of The Nihility that you can get from Stellar Warps.

If by the time Luka releases you still haven’t got his light cone, any cone for The Nihility should serve him well, especially those that interact with DoT.

Light cone Effect How to obtain
Resolution Shines As Pearls of Sweat When Luka hits an enemy and if the enemy is not already Ensnared, then there is a 60% base chance to Ensnare the target. Ensnared enemies’ defense decreases by 12% for one turn Gacha
Eyes of the Prey Increases Luka’s effect hit rate by 20% and increases DoT by 24% Gacha
Void At the start of battle, Luka’s effect hit rate increases by 20% for three turns Gacha

What are the best Honkai Star Rail Luka relics? 

As we don’t know the specifics of Luka’s abilities just yet, we can’t definitively say what his best relic set would be. However, we do know that he’s a physical damage dealer and treads the path of The Nihility, so we can make some broad assumptions based on that information.

Currently there’s only one relic set built specifically for physical damage dealers, and that’s Champion of Streetwise Boxing. If any of his skills scale based on his attack stat, this set will be a great choice. As for his Planetary Ornaments, as he’s likely going to be a debuffer, Pan-Galactic Commercial Enterprise is the best choice for Luka, especially if you can get a physical damage bonus on them.

Relic set Effect How to obtain
Champion of Streetwise Boxing Two equipped: increases physical damage by 10%
Four equipped: after Luka attacks or is hit by an enemy, his attack increases by 5% for the rest of the battle. This effect can stack up to five times
Cavern of Corrosion: Path of Jabbing Punch in Jarilo-VI’s Silvermane Guard Restricted Zone, or from the shop in Boulder Town
Thief of Shooting Meteor Two equipped: increases break effect by 16%
Four equipped: increases Luka’s break effect by 16%. He regenerates three energy when he inflicts weakness break on an enemy
Cavern of Corrosion: Path of Jabbing Punch in Jarilo-VI’s Silvermane Guard Restricted Zone
Pan-Galactic Commercial Enterprise Two equipped: increases Luka’s effect hit rate by 10%. Meanwhile, his attack increases by an amount equal to 25% of the current hit rate, up to a maximum of 25% bonus Immersion Reward devices in World 5 of the Simulated Universe

What are Honkai Star Rail’s Luka’s attacks and eidolons?

Who is Honkai Star Rail’s Luka? 

Luka is yet to appear in the main story for Honkai Star Rail, but we know a little bit about him from official social media posts, the version 1.2 livestream, and his signature light cone. The Honkai Star Rail Twitter describes him as “an optimistic and carefree fighter with a mechanical arm” and his splash art shows him inside the fight club ring in Belobog’s Underworld. He’s also a member of Wildfire alongside Honkai Star Rail’s Seele and Honkai Star Rail’s Natasha.

Both his light cone and his character description suggest that he has a tragic backstory that inspires him to protect the people around him. Hopefully, we’ll get to spend more time with him when he’s released and find out more about who he means when he mentions “the ones who ignited his determination in the first place.”

Honkai Star Rail’s Luka is voiced in English by Howard Wang, who you might recognize as Hikari Ku in Octopath Traveler 2 and Yomi Hellsmite in Master Detective Archives: Rain Code.
