Herta is a four-star ice character who treads the path of the Erudition, meaning she specializes in dishing out AoE damage.

Herta’s best light cone is the five-star Before Dawn, though The Seriousness of Breakfast and The Birth of the Self at superimpose level six are also strong options.

Her best relic set is Hunter of Glacial Forest paired up with the planar ornament set Space Sealing Station. When picking relics for Herta, we recommend prioritizing crit, attack%, and speed above other stats.

How to use Herta

As mentioned above, Herta is a four-star erudition character, meaning she specializes in multi-target damage. She also delivers shattering follow-up attacks which can turn the tide of battle to your favor.

Herta 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.

However, keep in mind that her normal attack only hits one enemy, whereas both her skill and ultimate are multi-target, and we’ve found that her skill has a higher chance of freezing enemies than her basic attack.

As such, when you’re facing more than one enemy, we recommend saving skill points to pop her skill as often as possible. Outside of that, just sit back and watch her ‘I’ll Take a Swing’ talent dish out follow-up attacks.

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

What’s the best light cone for Herta?

The best light cone for Herta is Before Dawn, as it dramatically boosts her crit, skill, and ultimate damage, and also increases her follow-up attack damage after she uses her skill or ultimate. However, this is a five-star light cone and is highly contested, so you may find better use for it on another character.

Alternatively, The Seriousness of Breakfast is a great option, especially in wave-based battles with lots of enemies. Her signature light cone, The Birth of the Self, comes in close behind, giving her a healthy boost to her follow-up attack damage.

However, if you’re looking for an alternate, be sure it aligns with the path of Erudition. For something a bit more accessible, Sagacity or Data Bank are good three-star options.

Light cone Effect How to obtain
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 three times Gacha
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
Sagacity When the wearer uses their ultimate, their attack increases by 24% for two turns Gacha
Data Bank Increases the wearer’s ultimate damage by 28% Gacha

What are the best relics for Herta?

You can equip Herta with a total of six relics – four from a standard set, and two from the Simulated Universe sets.

When it comes to boosting her ice attack, the best relic set for Herta is two pieces of Hunter of Glacial Forest and two pieces of Musketeer of Wild Wheat as it boosts her ice damage and attack. In terms of planar ornaments, we recommend Space Sealing Station, which also offers a hefty attack boost.

Find out more about the different relic sets and our recommendations in our Honkai Star Rail relics guide.
