Keen on building the best Arlan for your Honkai Star Rail team? Bringing the Head of Security at the Herta Space Station on to your team is a worthy one, but may require a little bit more planning to make his complex and oftentimes stressful kit work in your favor. Contrary to his Security Leader status, Arlan doesn’t really know how to take care of himself as his key passive ability increases his damage output the lower his HP gets. However, with some clever tweaking, he’ll become quite the powerhouse.
While not ranking the highest on our Honkai Star Rail tier list due to his complexity in the early game, a bit of patience will help him become a strong DPS option among the full roster of Honkai Star Rail characters, which is always made easier when you’re keeping up with our full list of monthly Honkai Star Rail codes.
What is the best Honkai Star Rail Arlan build?
The best build for Arlan is:
- Light Cone – On the Fall of an Aeon
- Relics – Band of Sizzling Thunder
- Planar Ornaments – Space Sealing Station set
- Eidolons – Turn the Tables
As mentioned, Arlan’s risky passive is his strength, which we can capitalize on by choosing equipment that offers multiple boosts to his ATK stat, where the main goal is to pull off the biggest ultimates possible on the first turn. By entering fights at low HP and with his energy fully charged, we can pair him with lightning and ATK-aligned equipment, and even aim for some later Eidolon survivability to get the most out of him.
Best Arlan Light Cones
The best Light Cones for Arlan are:
| Light Cone | Effect |
| On the Fall of an Aeon (five-star) | Whenever the wearer attacks, their attack is increased by 8% in this battle, up to four times. When the wearer inflicts weakness break on enemies, the wearer’s damage increases by 12% for two turns. |
| A Secret Vow (four-star) | Increases damage dealt by the wearer by 20%. The wearer also deals an extra 20% of damage to enemies with a higher HP percentage than the wearer. |
| Collapsing Sky (three-star) | Increases the wearer’s basic attack and skill damage by 20%. |
While some may think A Secret Vow meshes well with Arlan’s kit, we wouldn’t wholly disagree. He’s meant to be run at low HP, so the extra damage increase when attacking those with more HP than him is solid. However, On the Fall of an Aeon allows you to stack multiple attack boosts, on top of an added weakness break damage buff, making it overall the more consistent Light Cone option.
Best Arlan Relics
The best Arlan Relics are:
| Relics | Effect |
| Band of Sizzling Thunder set (four-piece) | Increases Lightning damage by 10%. When Arlan uses his skill, his attack increases by 20% for one turn. |
It’s a simple choice for Arlan, we want to increase damage across the board for him, which the lightning-aligned Band of Sizzling Thunder set provides. The key is timing the usage of his ultimate directly after his skill in order to take full advantage of that 20% increase provided by the relic set. With some good support or defense debuffs applied to the enemy, Arlan’s Frenzied Punishment will shock your foes into quick submission.
Best Arlan Planar Ornaments
The best Arlan Planar Ornaments are:
| Planar Ornaments | Effect |
| Space Sealing Station (two-piece) | Increases Arlan’s attack by 12%. When Arlan’s speed reaches 120 or higher, he’ll receive an extra 12% attack on top |
Our choice for Arlan’s best planar ornaments is the easily acquirable Space Sealing Station set, which is an equally easy jump in his attack stat, pairing him with a speed-increasing support unit like our best Asta build will help Arlan pop off quickly.
Best Arlan Eidolon
The best Eidolon for Arlan is:
| Eidolon | Effect |
| Level Four: Turn the Tables | When struck by a killing blow in battle, Arlan immediately restores HP to 25% of his max HP. The effect is removed after it is triggered once, or after two turns have expired. |
Let’s face it, Arlan’s passive talent lines him up to be one of the quintessential glass cannon builds in Honkai Star Rail, so ideally, we want to increase his viability through survivability with Turn the Tables. With Arlan requiring low HP to maximize his DPS, the first turns of any battle will be the most crucial, so working towards this later Eidolon level increases his ability to stay alive. Without the Eidolon, running a tank like Gepard or the fire Trailblazer can be a good alternative in the meantime.
Arlan Ascension Materials
The Ascension Materials for Arlan are:
- Lightning Crown of the Past Shadow (Ascension only)
- Destroyer’s Final Road
- Worldbreaker Blade/Lifeless Blade/Shattered Blade
- Squirming Core/Glimmering Core/Extinguished Core
As always, Worldbreaker Blades and Lifeless Blades can be the more worrisome of drops to guarantee from Calyx(Crimson): Path of Destruction. If you’ve been participating in the gacha side of things, you’ll likely have some Undying Embers left over that you could use to purchase the base Shattered Blades and synthesize them forward to use in Arlan’s valuable Trace upgrades.
Best Arlan team comp
Arlan’s best team comp is:
| Party Member | Role | Light Cones | Relics |
| Arlan | DPS | On the Fall of an Aeon | Band of Sizzling Thunder, Space Sealing Station |
| Tingyun | Support | Carve the Moon Weave the Clouds | Band of Sizzling Thunder, Sprightly Vonwacq |
| Gepard | Tank | Moment of Victory | Knight of Purity Palace, Belobog of the Ancients |
| Bronya | Support | But the Battle Isn’t Over | Eagle of Twilight Line, Fleet of the Ageless |
Arlan is best situated amongst plenty of damage-boosting support, provided in spades by Tingyun and Bronya’s attack-increasing ultimates. When popped in tandem, Arlan’s DPS soars into explosive territory, with the best Gepard build nearby to tank and keep the little lightning nuke from getting fried on the enemy’s upcoming turn, should they even survive. There’s plenty of energy regeneration at play here from our support units too, which should end any battle quickly and resolutely in Arlan’s favour.
Now, that’s everything you’ll need to put together the best Honkai Star Rail Arlan build. While chasing his level four Eidolon is a worthy effort, it’s made easier by checking out our Honkai Star Rail codes guide for free Stellar Jade to pull him or unlock even more Honkai Star Rail characters. Who knows who you’ll get?
