Aboard the Herta Space Station in Honkai Star Rail, Herta is the real top dog. She may appear as an adorable puppet in a cute little dress, but this sharp-tongued, ice hammer wielder is a top member of the Genius Society, known to have the highest IQ in The Blue. And our HSR Herta guide not only takes a look at who she is, but also her best build, light cones, and relics, as well as all of her eidolons.

To get familiar with the rest of the faces you meet on your trailblazing adventure, check out our list of Honkai Star Rail characters and Honkai Star Rail tier list. We also have other build guides just like this, including Honkai Star Rail’s Dan Heng, Honkai Star Rail’s March 7th, and Honkai Star Rail’s Natasha.

Who is Honkai Star Rail’s Herta?

Honkai Star Rail’s Herta is known as the human with the highest IQ in The Blue, and the Herta Space Station’s true master. She’s number 83 of the Genius Society, and only does what she’s interested in – dropping whichever project she’s working on as soon as something new comes along. She typically appears in the form of a ranged puppet, which is about 70% similar to how she looked as a child.

Herta’s English voice actor is PJ Mattson, who you may recognise as Sylvanas Windrunner from World of Warcraft, and her Japanese voice actor is Yamazaki Haruka, who has voiced many characters in a huge range of anime. She wields a hammer and has control over the element of ice, and her path is ‘The Erudition’.

What’s the best Honkai Star Rail Herta build?

Herta is a powerful damage dealer who specialises in AoE and follow-up attacks. She makes for a great sub-DPS, especially when you’re taking on large groups or waves of enemies in modes such as the Forgotten Hall and the Simulated Universe. All of her attacks have the ability to freeze enemies, disabling them for a set amount of turns, which offers great utility to her team.

We recommend pairing her up with a strong DPS from the path of The Hunt or The Destruction to form an enemy-shattering team that makes the most of her kit and enables your DPS to shine.

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

As with other Honkai Star Rail characters, Herta has her own light cone called the Birth of the Self, which is tailor-made to suit her kit. As such, it’s generally her best-in-slot for most situations.

However, if you’re looking for an alternate, be sure it aligns with the path of The Erudition. Before Dawn is a very strong five-star option that enhances her follow-up attacks. Alternatively, The Seriousness of Breakfast is a good choice as it boost her damage, and pushes her attack up even further after your team defeats an enemy.

Light cone Effect How to obtain
The Birth of the Self Increases damage dealt by the wearer’s follow-up attacks. If the current HP of the target enemy is below 50% of the wearer’s max HP, damage dealt by follow up attacks increases further Gacha
Before Dawn Increases the wearer’s crit damage by 32%, and their ultimate damage by 20%. After the wearer uses their skill or ultimate, they gain Somnus Corpus. Upon triggering a follow-up attack, they consume Somnus Corpus and their follow-up attack damage increases by 48% Gacha
The Seriousness of Breakfast Increases the wearer’s damage by 12%. For every defeated enemy, the wearer’s attack increases by 4%, stacking up to four times Gacha

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

We’re still testing out different relics on Herta, but as she relies on dealing ice damage, we recommend Hunter of Glacial Forest. Musketeer of Wild Wheat is also a good alternative as it boosts her attack and speed. Find out more about the different relic sets and our recommendations in our Honkai Star Rail relics guide.
