Sampo Koski, at your service! The customers are always right… Until they aren’t. Honkai Star Rail’s Sampo is a vibrant, energetic salesman 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. He’s pretty knowledgeable where it counts – even if there is clearly something else going on with him – and certainly knows how to put up a fight.

So, here’s what you need to know about Honkai Star Rail’s Sampo.

What’s the best Honkai Star Rail Sampo build?

We’ve found that while Sampo is capable of putting out some good damage and his key role revolves around his DoT, as he applies wind shear and debuffs to multiple enemies. This 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.

Eyes of the Prey (four-star) Increases Sampo’s effect hit rate when attacking by 24%, and his DoT damage by 24%. Gacha
Hidden Shadow (three-star) Sampo’s next basic attack after using a skill deals at least 60% of his attack as additional damage. Gacha
Void (three-star) Sampo’s effect hit rate increases by 20% for three turns at the beginning of a battle. Gacha

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.

In terms of his in-game abilities, 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.
