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?
