A fountain of knowledge with a brilliant mind and a calm temperament, Honkai Star Rail’s Welt is not only a cornerstone to lean on when your life goes off the tracks, he’s also a great asset to any team, incapacitating enemies and inflicting them with debuffs to ensure you victory. Welt’s a true MVP who’s always willing to support you and, in this guide, we go over his best build, relics, light cone, and more, so you can return the favour.

Who is Honkai Star Rail’s Welt?

Honkai Star Rail’s Welt kinda feels like the dad of the Astral Express crew – he’s the one you text when you find something new, and he’s always got an answer to help you out of a pickle. Wise and experienced in pretty much every topic, he’s a former Anti-Entropy Sovereign. The name ‘Welt’ is inherited from the world, as he’s saved Earth from annihilation multiple times.

Welt is a five-star character who has control over imaginary damage, creating portals and binding his enemies. Welt’s English voice actor is Corey Landis, and his Japanese voice actor is Hosoya Yoshimasa. He treads the path of the Nihility.

What’s the best Honkai Star Rail Welt build?

Honkai Star Rail’s Welt deals some great damage, but his core responsibility in most teams is his utility. He excels at imprisoning and slowing enemies, often incapacitating them and allowing other teammates to come in and finish the job. As one of two imaginary damage characters in the current roster (the other being Honkai Star Rail’s Luocha), he’s also extremely valuable when facing off against enemies with imaginary damage weakness.

When building Welt, you want to primarily focus on effect hit rate to maximise his utility, along with crit rate, crit damage, attack, and imaginary damage where possible.

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

In the Name of the World is a five-star light cone designed specifically for Welt. Its increased hit rate helps ensure his imprisonment and slow debuffs snag as many enemies as possible, allowing you to sweep through most battles in a breeze.

However, as it’s a five-star light cone obtainable through gacha, you’ll need a sprinkle of luck from the RNG gods to snag it. If you want to equip him with something in the meantime, aim for something that also increases his effect hit rate where possible, and ensure it also aligns with the path of Nihility.

Light cone Effect How to obtain
In the Name of the World Increases Welt’s effect hit rate by 28%. Also increases his crit rate by 8% if he deals additional damage. This effect can stack up to three times Gacha

Which relics should I use for Honkai Star Rail’s Welt?

As with his light cone, the best relic set for Welt in the Honkai Star Rail beta is Wastelander of Banditry Desert, due to its increase to effect hit rate. Its four-equipped buff suits his skill set perfectly, as he consistently applies debuffs, which means this set consistently increases his damage and crit rate.

Relic Effect How to obtain
Wastelander of Banditry Desert Two equipped: increases effect hit rate by 15%
Four equipped: when Welt attacks an enemy inflicted with a debuff, he deals 15% more damage with an additional 10% crit rate
Five equipped: increases effect hit rate by 15%
