Back to All Characters

Herta, also known as Madam Herta, is a formidable 5-Star Ice Erudition character in Honkai: Star Rail and an Emanator of Nous, the Aeon of Erudition. As member 83 of the Genius Society and founder of the Herta Space Station, her many puppets, including the playable 4-star version, reflect her younger self.

As an Erudition character, Herta excels in AoE scenarios but remains effective against fewer targets. She benefits from strong self-buffs and damage multipliers, including an 80% CRIT DMG boost for the team when paired with another Erudition unit and a three-turn ATK buff from her Ultimate. Herta requires minimal investment, offering F2P-friendly Light Cone and team options.

Herta’s playstyle centers on accumulating Inspiration stacks for herself and Interpretation stacks on enemies. Consuming an Inspiration stack enhances her Skill, while her Talent and Traces increase damage from her Enhanced Skill and Ultimate based on enemies’ Interpretation stacks. Here’s an overview of the best build options to optimize Herta’s powerful kit in Honkai: Star Rail.

Top Herta Relics in Honkai: Star Rail

When optimizing Herta, prioritize ATK, CRIT Rate, and CRIT DMG. Her Enhanced Skill and Ultimate drive most of her damage, so boosts to these abilities are critical. SPD is valuable but depends on team synergy.

The Scholar Lost in Erudition set is Herta’s best Relic choice, offering an 8% CRIT Rate boost and a 20% damage increase to her Skill and Ultimate. It also grants a 25% damage boost to the next Skill after an Ultimate. Herta’s Ultimate, Told Ya! Magic Happens, provides an Inspiration stack and immediate action to use her enhanced Skill.

For those without Scholar Lost in Erudition, the Hunter of Glacial Forest set is a strong alternative, providing a 10% Ice DMG boost and a 25% CRIT DMG increase for two turns post-Ultimate. Farming Scholar Lost in Erudition is more efficient, as it shares a Cavern of Corrosion with Sacerdos’ Relived Ordeal, a top support Relic set.

For new players, any 2-piece combination of CRIT Rate, Ice DMG, or ATK% works as a temporary option until better sets are obtained.

For Planar Ornaments, Izumo Gensei and Takama Divine Realm is the top choice, granting a 12% ATK boost and a 12% CRIT Rate increase when paired with another Erudition ally. This set enhances Herta’s Talent, amplifying Interpretation stack damage, while her A4 Trace boosts team CRIT DMG by 80% and increases Interpretation stacks from Erudition units. The set also benefits her Erudition partner.

Rutilant Arena is a solid alternative, offering an 8% CRIT Rate boost and a 20% Skill damage increase, with performance close to Izumo Gensei when substats are optimized. Its versatility makes it a practical farming option for multiple units.

Sigonia, the Unclaimed Desolation excels in Pure Fiction but is less effective in other modes. Since it can be farmed alongside Izumo Gensei, players may keep a dedicated Sigonia set for Pure Fiction.

Herta Ideal Stats

2,500-2,800 ATK (SPD Boots)

3,000-3,400 ATK (ATK% Boots)

3,600-3,900 ATK (ATK% Boots & Sphere)

Base SPD or 134 SPD

80%-100% CRIT Rate (In Combat)

180%-200%+ CRIT DMG (w/ A4 Trace)

With Herta’s A4 Trace providing 80% CRIT DMG, a CRIT Rate chest is recommended to reach 100% CRIT Rate. Support units like Sunday or Remembrance Trailblazer can address CRIT Rate gaps.

Herta’s SPD needs vary based on teammates and Eidolons. She can function at base SPD with allies like Jade, who boosts her SPD by 30 and aids stack generation via Follow-Up Attacks.

Energy from Herta’s A2 and A4 Traces is fixed and unaffected by an Energy Regeneration Rope.

Herta’s Eidolons reduce SPD reliance. E1 lowers the A2 Trace’s 42 Interpretation stack threshold to 28, E2 advances her actions after Enhanced Skill use, and E4 grants a 12% SPD boost to Erudition allies, enabling 134 SPD without SPD boots. With SPD boots and optimal teammates, Herta can hit 146 or 164 SPD.

Best Herta Light Cones in Honkai: Star Rail

Herta’s signature Light Cone, Into the Unreachable Veil, is her best, offering the highest base ATK among Erudition Light Cones. At S1, it provides a 12% CRIT Rate boost and a 60% damage increase to her Skill and Ultimate for three turns post-Ultimate. If the Ultimate costs 140+ Energy, it recovers a Skill Point, aiding Skill Point-heavy teams.

Alternatives include Night on the Milky Way, which excels with multiple enemies, and An Instant Before A Gaze, boosting CRIT DMG and Ultimate damage. Before Dawn and Yet Hope Is Priceless are strong stat sticks, enhancing CRIT DMG, Skill, and Ultimate damage or CRIT Rate, respectively.

Night on the Milky Way’s effectiveness drops with fewer than four enemies or without its DMG bonus.

For 4-star options, Today Is Another Peaceful Day and Geniuses’ Repose are excellent for F2P players. At S5, Today Is Another Peaceful Day can outperform many 5-star Light Cones and is more consistent than Night on the Milky Way.

For new players, free Erudition Light Cones—Eternal Calculus, The Day The Cosmos Fell, and The Seriousness of Breakfast—are viable at S5.
