Sampo Koski, at your service! The customers are always right… Until they aren’t. Honkai Star Rail’s Sampo is a vibrant, energetic salesman from Jarilo-VI, who always seems to be getting himself into sticky situations – whether he’s running from the Silvermane Guards, or launching into battle to save his pals. Luckily, he’s pretty darn knowledgeable where it counts, and certainly knows how to put up a fight. And if you want this charming wild card to join your team, then you’re in the right place. Our Sampo guide goes over his attacks, eidolons, and best build, including the top light cones and relics to kit him out with.

If you want to get acquainted with the rest of the Honkai-tonks, check out our Honkai Star Rail tier list and Honkai Star Rail characters guides. We also have more build guides just like this, including Honkai Star Rail’s Welt and Honkai Star Rail’s Silver Wolf.

Who is Honkai Star Rail’s Sampo?

Imagine Futurama’s Zap Brannigan mixed with Genshin Impact’s Itto, and you’re pretty much there. Honkai Star Rail’s Sampo is a loveably goofy, silver-tongued salesman, always on the hunt to make a profit. While he may appear a little cowardly or flaky at times (the first time you meet him, he’s hiding in a pile of snow, after all), his knowledge makes him a valuable pal – though becoming his ‘customer’ isn’t always the best bet. Customers can easily become commodities for the right price, after all.

Sampo is a four-star character who has control over the power of wind, and treads the path of the Nihility. His English voice actor is Roger Rose, whereas his Japanese voice actor is Hirakawa Daisuke.

What’s the best Honkai Star Rail Sampo build?

As we’re still in the beta at the moment, we’re currently learning about the fine details of Honkai Star Rail’s Sampo and his best build. However, we’ve found that, while he’s capable of putting out some good damage, his key role revolves around his utility, as he’s capable of applying DoT’s and debuffs to multiple enemies. His wind shear application and blinding technique pave the way for other high-impact damage dealers like Honkai Star Rail’s Jing Yuan to hop in and finish enemies off.

When building your Sampo, you should aim to increase his effect hit rate as it allows him to apply his DoT and debuffs to as many enemies as possible. We believe you should also aim to increase his attack, wind damage, and speed.

Which light cone should I use for Honkai Star Rail’s Sampo?

The four-star light cone Eyes of Prey is tailored to Sampo’s kit, and is pretty easy to get through the normal gacha. However, if you’re looking for an alternate, aim for something that also increases his effect hit rate and/or DoT damage, and ensure it aligns with the path of Nihility in order to activate its skill.

Light cone Effect How to obtain
Eyes of the Prey Increases Sampo’s effect hit rate when attacking by 24%, and his DoT damage by 24% Gacha

Eagle of Twilight Line Two equipped: increases wind damage by 10%
