Honkai Star Rail’s Arlan does a stellar job of protecting the Herta Space Station. Okay, he may not win every battle, but he’s more than willing to put his life on the line to protect those around him. But regardless of how brave or skilled the head of the Herta Space Station’s security department is, no one should have to shoulder such responsibility alone.
If you want to introduce yourself to the rest of the inhabitants of Herta Space Station, head over to our Honkai Star Rail tier list and Honkai Star Rail banner guides. You can grab some free resources with our Honkai Star Rail codes guide. We’ve also got a heap more build guides just like this one, including Honkai Star Rail’s Guinaifen, Honkai Star Rail’s Topaz, and Honkai Star Rail’s Trailblazer.
Let’s jump into everything you need to know about Honkai Star Rail’s Arlan.
What’s the best Honkai Star Rail Arlan build?
| Best light cone | The Unreachable Side |
| Light cone alternatives | A Secret Vow |
| Best relic set | Band of Sizzling Thunder and/or Longevous Disciple |
| Best planar ornament set | Rutilant Arena |
| Main stats |

| Sub-stats |

For Arlan’s best build, you should equip him with the five-star light cone The Unreachable Side, a combination of Band of Sizzling Thunder and Musketeer of Wild Wheat, and Rutilant Arena. His damage scales based on his attack, but his HP is equally important so make sure to balance the two stats while also boosting his lightning damage bonus, crit rate, and crit damage.
How should I use Arlan?
Arlan is a lightning-wielding DPS with high damage and low survivability, he plays the role of a glass cannon in most scenarios. He specializes in taking down single targets, and his skill sees him sacrifice a portion of his HP in order to deal more damage, though he can’t use this skill if his HP is insufficient. His passive also sees his damage increase based on his lost HP.
What are the best light cones for Arlan?
Honkai Star Rail Blade‘s light cone The Unreachable Side fits Arlan’s HP-cutting moveset perfectly, boosting his crit rate and max HP, as well as buffing his attack when he cuts his own health or when enemies attack him. However, it’s a limited five-star light cone, so can be a pain to acquire.
The four-star light cone A Secret Vow is tailored to Arlan’s kit, both increasing his flat damage and allowing him to deal extra damage when an enemy has a higher HP percentage than him, which, due to his skills, is likely to be almost always active. However, if you can’t get your hands on A Secret Vow for whatever reason, you can equip him with any light cone that aligns with the path of The Destruction, preferably one that also boosts his attack.
| Light cone | Effect | How to obtain |
| The Unreachable Side | Increases Arlan’s crit rate by 18% and increases his max HP by 18%. When enemies attack Arlan or he consumes his own HP, his damage increases by 24%. This effect is removed after Arlan uses an attack | Limited gacha |
| A Secret Vow | Increases the damage Arlan deals by 20%. He also deals an extra 20% damage to enemies with a higher HP percentage than him | Gacha |
| Shattered Home | Increases the damage Arlan deals to enemies that have 50% of their max HP remaining by 20% | Gacha |
| Collapsing Sky | Increases Arlan’s basic attack and skill damage by 16% | Gacha |
What are the best relics for Arlan?
When it comes to Honkai Star Rail relics, the best set for Arlan is the Band of Sizzling Thunder, as it increases his lightning damage and shock damage. He’s a clear main DPS character, so anything that boosts his elemental damage and attack stat is beneficial. We’ve also tried pairing two pieces of Band of Sizzling Thunder with two pieces of Musketeer of Wild Wheat to increase his attack stat.
Longevous Disciple is also a decent option for Arlan, increasing his max HP and offering a similar effect to Blade’s light cone that’s much easier to get your hands on.
We recommend Fleet of the Ageless for his planar ornament set in the early game to give him even more HP to use with his attacks. Later on, Rutilant Arena is a much better fit for Arlan as a main DPS, boosting his crit rate, basic attack damage, and skill damage.
| Relic set | Effect | How to obtain |
| Band of Sizzling Thunder | Two pieces equipped: increases lightning damage by 10% Four pieces equipped: increases Arlan’s attack by 20% for one turn after he uses his skill |
Cavern of Corrosion: Path of Holy Hymn in the Xianzhou Luofu’s Cloudford |
| Longevous Disciple | Two pieces equipped: increases max HP by 12% Four pieces equipped: when Arlan is hit or has his HP consumed by an ally or himself, his crit rate increases by 8% for two turns and up to two stacks |
Cavern of Corrosion: Path of Elixir Seekers in The Xianzhou Luofu’s Alchemy Commission |

What’s the best team comp for Arlan?
While Arlan certainly isn’t the best DPS on the Honkai Star Rail tier list, he can be pretty powerful with the right team and build. For healing, Natasha is a no-brainer as her skill can directly target Arlan when his HP is getting low. Then, combine whichever supports, tanks, and sub-DPS characters suit your playstyle.
Here’s an example of a strong Arlan team comp:
| Main DPS | Support | Support | Healer |
 Arlan |
 Tingyun |
 Bronya |
 Natasha |
