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.

Let’s jump into everything you need to know about Honkai Star Rail’s Arlan.

What’s the best Honkai Star Rail Arlan build?

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.

It’s important to pick the right healer for Arlan’s team. Honkai Star Rail’s Natasha is fitting for the role, as you can control when she heals her allies, and her ultimate is a great emergency button if Arlan’s health falls too low to use his skill. We recommend prioritizing attack, HP, and lightning damage boost stats when building Arlan. The reason we recommend HP is that his buffs and skills are based on a percentage of his max HP rather than a flat rate, so ensuring he has high max HP means he can fall below the required threshold without being at risk of dying in one hit.

What are the best light cones for Honkai Star Rail’s Arlan?

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.

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

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. For sub-stats, we once again recommend aiming for more attack, HP, and lightning damage. After this, you should ensure that he has a decent crit rate/crit damage ratio and some extra energy restoration.

We recommend Fleet of the Ageless for his planar ornament set to give him even more HP to use with his attacks.
