Honkai Star Rail Arlan Build

Are you wondering how well Arlan compares to other characters in the game? Check out our Honkai Star Rail tier list guide.

Honkai Star Rail Arlan Story Introduction

As the head of Herta Space Station’s security department, Arlan is one of the most caring characters that you might want to consider getting. Even tho Arlan has no mastery in scientific research, as the head of security, Arlan is willing to risk his life to protect the staff who value research so very much. He is used to the pain and wears his scars like badges of honor.

Together with his little dog, Peppy, that will leave a bright smile on Arlan’s face, we are here to help you make Arlan more reliable and carries victory to your team by giving you the best build for Arlan!

Best Honkai Star Rail Arlan Build

Since Arlan is a Destruction Path character, he’s suitable to become your All-rounder main DPS. His kit plays with manipulating his HP, sacrificing some portion of his HP to dish out big damage. With DMG increase, the lower his HP be; Arlan is your double edge sword lightning DPS character that could nuke big damage towards a single enemy.

For Arlan’s Relics and Planar Ornament build, we highly suggest you to go with the lightning Relics Band of Sizzling Thunder 4 set since it will increase Arlan’s damage even further, and you can keep using the skill from his turn to always refresh the ATK buff duration. Arlan’s skill and Ultimate is his bread and butter, so we would suggest you go with CRIT Rate Planar Ornament because it will also buff either his Skill or Ultimate DMG, depending on which Ornament you’re choosing. You can actually go with whichever CRIT Rate since both are samely useful for Arlan.

As for Arlan’s Light Cone build, you can focus on the Destruction Path Light Cone since we can’t activate the effect from the other Light Cone’s Path. All of Destruction Path Light Cones fit Arlan well, but we recommend you equip the Light Cone that has self-sustainability so that Arlan can keep sacrificing his HP to dish out big damage. Here are the best Light Cone, Relics, Planar Ornament, and the best Team Comp for Arlan.

Honkai Star Rail Arlan Best Light Cones

A Secret Vow
Increases DMG dealt by the wearer by 20/25/30/35/40%
The wearer also deals an extra 20/25/30/35/40% of DMG to enemies with a higher HP percentage than the wearer.

Arlan’s Best in Slot Light Cone and also his Signature Light Cone.

Since Arlan will often have his HP lower compared to the enemies, he can also proc the additional extra DMG that will help him deliver high nuke damage to the enemy.

Something Irreplaceable
Increases the wearer’s ATK by 20/25/30/35/40%. When the wearer defeats an enemy or is hit, immediately restores HP equal to 6/7.5/9/10.5/12% of the wearer’s ATK. At the same time, the wearer’s DMG increases by 20/25/30/35/40% until the end of their next turn. This effect cannot stack and can only trigger 1 time per turn.

Arlan’s secondary Best in Slot Light Cone.

It will increase Arlan’s DMG, and the best thing is whenever Arlan defeats an enemy or gets hit; he will recover some HP that scales from his ATK.

Since we will invest a lot of ATK for Arlan, the potential healing will be very useful for him too.

On the Fall of an Aeon
Whenever the wearer attacks, increase their ATK by  8/10/12/14/16% in this battle, up to 4 time(s).When the wearer inflicts Weakness Break on enemies, the wearer’s DMG increases by  12/15/18/21/24% for 2 turn(s).

Great ATK investment if you will have a long battle with Arlan.

Since it will take time to take benefit of the full stack, this Light Cone is usually more useful for fighting bosses.

Nowhere to Run
Increases the wearer’s ATK by 20/25/30/35/40%. Whenever the wearer defeats an enemy, they restore HP equal to 12/15/18/21/24% of their ATK.

Great 4-star substitution of Something Irreplaceable.

This Light Cone will give a higher heal rate than that Light Cone, but it will only heal Arlan if he can defeat the enemy himself.

Mutual Demise
If the wearer’s current HP is less than 80% of their Max HP, CRIT Rate increases by 16/19/22/25/28%.

Arlan often has their HP below 80% due to the HP drain by using his skill, so it will be easy to gain an extra CRIT Rate.

This Light Cone is very useful for Arlan since, especially during the early-mid game, it will be quite challenging to have nice CRIT Rate Relics. So this Light Cone will help Arlan slightly closer to keep triggering the critical hit.

Honkai Star Rail Arlan Best Relics

Since Arlan is a lightning character and his damage also scales from his ATK, we highly recommend you to go with 4 set Band of Sizzling Thunder since it will also buff his Lightning DMG and his ATK after he used his skill. But if you don’t have 4 set Lightning Relics yet, you can also go with ATK Relics, either 4 set ATK Relics or 2 set Lightning 2 set ATK Relics.

Band of Sizzling Thunder
2 Set: Increases Lightning DMG by 10%.
4 Set: When the wearer uses Skill, increases the wearer’s ATK by 25% for 1 turn(s).

Musketeer of Wild Wheat
2 Set: ATK increases by 10%.
4 Set: The wearer’s SPD increases by 6% and Basic ATK DMG increases by 10%.

Band of Sizzling Thunder
Musketeer of Wild Wheat

2 Set: (Sizzling Thunder) Increases Lightning DMG by 10%.
2 Set: (Wild Wheat) ATK increases by 10%.

Honkai Star Rail Arlan Best Planar Ornaments

Arlan’s kit revolves around relying on his skill and his Ultimate, so it would be better to go with CRIT Rate Ornament. Here are the recommended Planar Ornaments that you can use for Arlan, which we have ordered it ascending from the best to the least.

Celestial Differentiator
2 Set: Increases the wearer’s CRIT Rate by 8%.
When the wearer’s current CRIT Rate reaches 80% or higher, the wearer’s Basic ATK and Skill DMG increase by 20%.

Space Sealing Station
2 Set: Increases the wearer’s ATK by 12%.
When the wearer’s SPD reaches 120 or higher, the wearer’s ATK increases by another 12%.

Inert Salsotto
2 Set: Increases the wearer’s CRIT Rate by 8%.
When the wearer’s current CRIT Rate reaches 50% or higher, the wearer’s Ultimate and follow-up attack DMG increases by 15%.

Honkai: Star Rail Arlan Best Team Comp

For Arlan’s team comp, having a Healer is a must since Arlan will always deplete his HP whenever we use his skill. Pairing Arlan with Harmony Path character is also very recommended since it will increase his damage even further. Uniquely for Arlan, it’s also quite useful to pair him together with Pela because Pela can shred the enemy’s DEF lower, making Arlan the single nuke DPS in your team that can potentially one-shot some of the enemies. If you want to play safe, you can also go with Preservation Path character, especially those that have the taunt skill so that the enemy will never touch Arlan at all.

Here are some examples of Arlan team composition that you can use.


That is how you can get the best Honkai Star Rail Arlan Build. One thing you need to know, Honkai Star Rail is still in the 3rd (final) Close Beta phase, meaning that there will potentially be some adjustments and different configurations for the final release.

Despite Arlan sacrificing his HP in combat, he actually one of the strong nuke characters that can give you a big damage number. He can potentially be your highest damage generator if you invest a lot of ATK, CRIT, and Lightning DMG for Arlan. Just make sure to pair him with a healer since he can die very quickly due to the HP drainage.
