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.

What’s the best Honkai Star Rail Arlan build?

  • Body: crit rate
  • Feet: speed
  • Planar sphere: lightning damage
  • Link rope: attack%
  • Crit rate and damage
  • Attack%
  • Speed

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 Longevous Disciple, and Firmament Frontline: Glammoth.

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.

On the Fall of an Aeon is also a powerful option that’s a little easier to acquire, as you can buy it from Herta’s Store for eight Herta bonds. Arlan’s damage output scales based on his attack, so the incremental increase throughout the battle helps to lift his power to new heights.

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
On the Fall of an Aeon Whenever Arlan attacks, his attack is increased by 8% in this battle, up to four times. When he inflicts weakness break on enemies, Arlan’s damage increases by 12% for two turns Herta’s Store
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

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.

For planar ornaments, Rutilant Arena is a great fit for Arlan as a main DPS, boosting his crit rate, basic attack damage, and skill damage. Firmament Frontline: Glamoth is also viable even if you’re only reaching its baseline speed, offering a generalized attack and damage buff rather than focusing on his basic attack and skill.

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
Musketeer of Wild Wheat Two pieces equipped: increases Arlan’s attack by 12%
Four pieces equipped: increases Arlan’s speed by 6% and his basic attack damage by 10%
Cavern of Corrosion: Path of Drifting in Jarilo-VI’s Corridor of Fading Echoes

Honkai Star Rail's Arlan fighting in the Space Station

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:
