Herta — the eccentric genius of Herta Space Station in her 4-star puppet form — is one of the most iconic early characters in Honkai Star Rail. An Ice Erudition follow-up attacker with a trigger-happy AoE Talent, she has found renewed relevance in patch 4.3 as a battery partner for her own 5-star true form, The Herta. This Herta build guide covers everything — best Light Cones, Relics, stat priorities, team compositions, and Eidolons — to get the most out of her in the current patch.

Who Is Herta (4-Star) in Honkai Star Rail?

Herta is a 4-star character following the Path of Erudition with the Ice element. She is member #83 of the Genius Society and the owner of Herta Space Station — a self-described genius who only does what interests her and operates in the galaxy primarily through a network of puppet bodies. The 4-star Herta that players interact with is one such puppet: a smaller, chibi-style form that she admits is “about 70% accurate” to her real appearance.

On the battlefield, Herta is an AoE follow-up attacker. Her Talent — Fine, I’ll Do It Myself — triggers a free AoE Ice follow-up attack whenever any ally’s attack reduces an enemy’s HP to 50% or lower. This happens automatically, off-turn, with no Skill Point cost and no player input. In multi-target content where enemies are constantly being pushed to the 50% HP threshold, Herta fires her Talent follow-up on nearly every single allied action — contributing a continuous stream of AoE Ice damage without ever taking up a dedicated slot of active play.

In patch 4.3, Herta’s primary competitive niche is as a Sticker stack generator for The Herta. Her frequent AoE hits contribute stacks to The Herta’s passive system far more consistently than most characters, making her the natural 4-star partner in budget Erudition compositions. She also functions independently as a strong sub-DPS in Pure Fiction and multi-wave content.

Herta Skills and Abilities

Basic ATK – Frigid Cold Arrow

Deals Ice DMG to a single enemy equal to 50% of Herta’s ATK. A simple single-target filler action used when Skill Points are low. Generates 20 Energy. Less damage than her Skill but free and consistent.

Skill – Frost Baptism

Deals Ice AoE DMG to all enemies equal to up to 100% ATK. If the enemy’s current HP is 50% or higher, the DMG dealt to that target increases by 20%. Generates 30 Energy. A clean AoE attack that hits harder against enemies above the half-health threshold — synergising with her Talent’s trigger condition by softening high-HP enemies toward the 50% mark for the Talent to fire.

Ultimate – It’s Magic, I Added Some Magic

Deals Ice AoE DMG to all enemies equal to up to 120% ATK. A fast-cycling Ultimate with a 100 Energy cost — relatively low, making it accessible with modest Energy Regeneration investment. Use it to deal AoE burst damage on demand. The Hunter of Glacial Forest 4-piece effect triggers after the Ultimate, granting a CRIT DMG boost for the subsequent attacks.

Talent – Fine, I’ll Do It Myself

The heart of Herta’s kit. Whenever an ally’s attack reduces an enemy’s HP to 50% or lower, Herta immediately launches an AoE Ice follow-up attack against all enemies equal to up to 50% ATK. This attack costs no Skill Points, requires no turn from Herta, and fires automatically in response to ally actions. In Pure Fiction with 5 enemies constantly being chipped below 50% HP, this can fire on every single allied attack — including The Herta‘s frequent Skill hits. The Talent follow-up is also eligible for critical hits, making CRIT stats important despite the low base multiplier.

Technique – Puppet Theatre

Creates a field that delays enemy attacks and on battle entry, applies Ice DMG to all enemies with a chance to Freeze them for 1 turn. Frozen enemies cannot take action and take additional Ice DMG when the Freeze expires. Always use this before combat — the opening Freeze buys a free turn and deals immediate AoE damage.

Major Traces

Puppet’s Counterattack (A2): When the Talent follow-up attack triggers and all enemies are frozen, the follow-up additionally deals DMG equal to 50% of Herta’s ATK to the frozen targets. This bonus applies when Ice Weakness Break occurs and the Freeze status is active — specifically rewarding Ice-weak content and adding bonus damage on top of the Freeze expiry hit
Fine-tuned Puppetry (A4): When Herta’s Talent is triggered, if the current enemy’s HP is 50% or lower, the Talent’s follow-up attack DMG increases by 20%. This directly rewards the core scenario the Talent is designed for — enemies already at low HP trigger not just the follow-up but also a 20% DMG boost on it. A meaningful passive amplifier in sustained fights
Controlled Temperature (A6): At the start of the battle, Herta’s action is advanced forward by 20%. This gives her a meaningful head start, allowing her to act and use her Skill before many allies take their first turn — which in turn creates more opportunities for the Talent to proc on subsequent ally actions during the opening wave

Herta Best Light Cones (4.3)

1. Night on the Milky Way (Best Multi-Target Option)

Himeko‘s signature Light Cone and Herta’s best DPS option in multi-target content. It provides stacking ATK% for each enemy on the field (up to 5 stacks), and a 30% DMG bonus for 1 turn after Weakness Break. In Pure Fiction with 5 enemies, Herta reaches maximum ATK% stacks immediately and maintains them as long as enemies are present. The Weakness Break DMG bonus also pairs well with Herta’s frequent AoE attacks dealing Ice DMG to Ice-weak enemies. Sports Illustrated and multiple sources identify this as Herta’s strongest general-use Light Cone for wave-clearing scenarios.

2. Into the Unreachable Veil (The Herta Companion Build)

When running Herta specifically as a partner for The Herta, this Light Cone is worth considering — it provides CRIT Rate and after using Ultimate, boosts Skill and Ultimate DMG significantly for 3 turns. The SP recovery from using the Ultimate also helps in team contexts where Herta needs to contribute Sticker stacks fast. Recommended for players whose primary use for Herta is The Herta battery role.

3. Before Dawn (5-Star Erudition Alternative)

Provides +36% CRIT DMG and boosts Skill and Ultimate DMG. All three of Herta’s main damage actions — Skill, Ultimate, and Talent follow-up — benefit from its stats. The CRIT DMG stacks well with Hunter of Glacial Forest’s post-Ultimate CRIT DMG bonus. A clean choice for players who have this cone available from other Erudition characters.

4. Today Is Another Peaceful Day (Best 4-Star – Battle Pass)

Converts Max Energy into a DMG% bonus. At Herta’s 100 Energy cost, the bonus is meaningful and applies to all her attacks. A widely available 4-star cone from the Nameless Honor shop that provides a consistent flat DMG% increase without conditional requirements. The recommended 4-star option for most players.

5. Night on the Milky Way (4-Star Version – Geniuses’ Repose)

Provides ATK% and, after defeating an enemy, increases CRIT DMG by 24% for 3 turns. In Pure Fiction wave content where kills happen frequently, the CRIT DMG bonus is active almost continuously. A strong 4-star alternative for players without Night on the Milky Way or Today Is Another Peaceful Day.

6. The Seriousness of Breakfast (4-Star F2P)

Purchasable from the Forgotten Hall Store. Provides a flat DMG% bonus and ATK% stacks from defeated enemies. No conditional requirements beyond killing enemies — reliable in most combat scenarios. Use this as a fallback when better options are unavailable.

7. Passkey (Herta Battery Role)

Provides Energy Regeneration Rate, significantly accelerating Herta’s Ultimate cycling. In The Herta team compositions where Herta’s primary goal is generating as many Sticker stacks as possible through frequent AoE hits, faster Ultimate cycling means more AoE actions and more stacks per minute. Use this specifically in The Herta battery compositions. Sacrifice personal DPS for team utility.

Herta Best Relic Sets (4.3)

Hunter of Glacial Forest (4-Piece) – Best General Option

The dedicated Ice relic set and Herta’s most recommended option for general DPS use. The 2-piece gives +10% Ice DMG. The 4-piece boosts CRIT DMG by 25% for 2 turns after the wearer uses their Ultimate. Herta’s Ultimate cycles frequently (100 Energy cost), meaning this bonus is active for much of the fight. The combined Ice DMG and CRIT DMG amplification covers both her Skill, Ultimate, and Talent follow-up hits cleanly. Recommended by Zilliongamer, LootBar, and SI for general Herta builds.

The Ashblazing Grand Duke (4-Piece) – Best Follow-Up Focused Option

The follow-up attack relic set. The 4-piece gives +20% follow-up attack DMG and stacks +6% ATK each time the wearer’s follow-up deals DMG, up to 8 stacks. Since Herta’s Talent fires her follow-up constantly in multi-target content, she can reach high ATK stack counts quickly. SI recommends this specifically for Herta builds oriented around maximising Talent follow-up output. In Pure Fiction where the Talent fires on almost every allied action, this set stacks rapidly and provides consistent ATK% bonuses throughout the fight.

Hunter of Glacial Forest (2) + Musketeer of Wild Wheat (2)

A clean transitional combination. +10% Ice DMG from Hunter and +12% ATK from Musketeer. No conditional requirements, easy to assemble. Use while farming for a complete 4-piece set with good substats.

Herta Best Planar Ornaments (4.3)

Inert Salsotto (Best Overall)

The top Planar Ornament for Herta across multiple sources including Zilliongamer and LootBar. It provides +8% CRIT Rate and, when the wearer’s CRIT Rate reaches 50% or higher, increases Ultimate and Follow-Up DMG by 15%. Both the Ultimate and Herta’s Talent follow-up receive this 15% bonus — which covers her two most important damage outputs simultaneously. Reaching the 50% CRIT Rate threshold is straightforward with CRIT Rate body and relic substats. Always use Inert Salsotto unless your CRIT Rate consistently falls below 50%.

Space Sealing Station (ATK Alternative)

Provides +12% ATK with an additional +12% at 120 SPD. Herta’s base SPD is 100 — reaching 120 requires SPD boots or substats. Use this specifically if your Inert Salsotto pieces have poor substats and your Space Sealing Station pieces are significantly better-rolled. The ATK bonus applies to all attacks including the Talent follow-up.

Duran, Dynasty of Running Wolves (Follow-Up Teams)

Stacks up to 5 times when follow-up attacks are used, increasing overall DMG. At 5 stacks, also provides CRIT DMG. In teams with multiple follow-up attackers alongside Herta (such as The Herta and Aventurine), this ornament reaches and maintains max stacks quickly. A strong option specifically in follow-up heavy teams.

Herta Best Stats and Substats (4.3)

Main Stats

Body: CRIT Rate
Boots: ATK% (or SPD if using Space Sealing Station)
Planar Sphere (Orb): Ice DMG Boost
Link Rope: ATK% (general DPS) or Energy Regeneration Rate (The Herta battery build)

Substat Priority

CRIT Rate (aim for 65%+ for Inert Salsotto activation and reliable crits on follow-up)
CRIT DMG (aim for 140%+)
ATK% and Flat ATK
SPD (secondary — faster Herta takes more turns and creates more opportunities for ally-triggered Talent procs)

Herta has +22.4% Ice DMG, +18% ATK, and +12.5% DEF from her minor traces — a generous offensive base that reduces the pressure on relic substats for those specific stats. Focus relic investment on CRIT Rate and CRIT DMG. The Talent follow-up scales off ATK and is eligible for critical hits — treating it as an additional DPS action that fires off-turn means CRIT stats multiply her effective output significantly more than the base 50% ATK multiplier suggests.

Herta Best Team Compositions (4.3)

Best Team (Battery Role): The Herta, Herta, Tribbie, Aventurine

Herta’s most valuable team in 4.3 — as a Sticker stack generator for The Herta. Every AoE hit from Herta’s Talent follow-up and Skill contributes Sticker stacks to The Herta’s passive system, which she needs to power her enhanced attacks. Since Herta’s Talent fires on nearly every allied action in multi-target content, and The Herta herself attacks frequently, the combination creates an enormous Sticker generation loop. Tribbie adds universal RES PEN and AoE follow-up damage. Aventurine sustains with shields and his own follow-up attacks that also generate Sticker stacks. A self-reinforcing team where every character contributes hits.

Pure Fiction Wave Clear: Herta, Argenti, Robin/Tribbie, Sustain

A strong dual-Erudition Pure Fiction team without requiring The Herta. Argenti‘s constant AoE attacks push enemies below 50% HP frequently, triggering Herta’s Talent on almost every hit. Robin provides action advance and ATK% buffs that amplify both DPS characters simultaneously. This team excels at wave clearing in Pure Fiction where Herta’s Talent fires almost continuously.

Budget Erudition: The Herta, Herta, Ruan Mei, Gallagher

A budget-friendly version of the The Herta team using Ruan Mei for Break and DMG support and Gallagher for sustain. Herta continues her Sticker battery role. A viable team for players who have The Herta but lack premium 5-star supports like Tribbie or Aventurine.

Ice Freeze Team: Herta, Yanqing, Robin, Fu Xuan

A fun Ice-focused team where Herta’s Talent follow-up contributes constant Freeze pressure alongside Yanqing‘s Frozen specialisation. Herta’s A2 Trace provides bonus damage when all enemies are Frozen, creating a thematic synergy. Robin and Fu Xuan round out the team. A thematic and entertaining setup, if not the most meta-optimal.

Characters Who Synergise With Herta

The Herta – Primary partner; Herta’s AoE hits generate Sticker stacks for her most powerful attacks
Argenti – High AoE action rate that constantly triggers Herta’s Talent in Pure Fiction
Jade – Another follow-up attacker who hits frequently, triggering Herta’s Talent off-turn
Tribbie – Universal RES PEN; her follow-up attacks also trigger Herta’s Talent on enemy HP crosses
Robin – Action advance and ATK% buffs; her Concert state fires additional instances that push enemies below 50% HP
Ruan Mei – Break support and DMG amplification in Ice-weak content
Aventurine – Shields and follow-up attacks that contribute stacks and trigger Herta’s Talent
Serval – Another free Erudition character who pairs with Herta in budget Erudition teams
Kafka – Her follow-up detonations push enemies below 50% HP frequently, triggering Herta’s Talent repeatedly

Herta Eidolons – Are They Worth It?

Herta is a standard banner character who accumulates Eidolons naturally over time. Her Eidolons are meaningful and notably power up her follow-up output significantly.

E1 – Wizard of Spirit

When the Talent follow-up attack is triggered, if the current enemy’s HP is 50% or lower, the Talent follow-up attack DMG is increased by 25%. Combined with the A4 Trace’s +20% boost in the same scenario, this brings the total bonus to +45% Talent follow-up DMG against targets already below half HP. Since the Talent consistently fires against low-HP targets in wave-clearing content, E1 is a substantial and reliable DPS upgrade.

E2 – Midnight Dreams

After the Talent triggers, Herta regenerates 5 Energy. Given how frequently the Talent fires in multi-target content — potentially multiple times per turn across multiple allies — this provides significant passive Energy generation that dramatically reduces the turns needed to reach her 100-cost Ultimate. E2 makes Herta’s Ultimate significantly more accessible in sustained fights.

E4 – Puppet Exhibition

After using Ultimate, Herta immediately takes another action. An extra turn after the Ultimate is a strong quality-of-life upgrade — she can follow up immediately with a Skill for another AoE hit, which then triggers the Talent if enemies are at the right HP threshold. Meaningful in content where quick follow-through matters.

E6 – Empathic Will

Herta’s Talent follow-up attack now also triggers when the target’s current HP is 40% or lower — expanding the trigger threshold and making the Talent fire more frequently across the fight. Also increases the Talent’s DMG by 10%. A clean E6 that broadens her trigger conditions and adds a passive damage boost.

Recommended approach: take Eidolons naturally. E0 Herta is fully functional as a sub-DPS and Sticker battery. E1 and E2 are the most impactful — significant follow-up DMG boost and passive Energy generation from frequent Talent procs. Both arrive naturally from standard banner pulls over time.

Herta Rotation Guide

Herta’s rotation is simple because much of her damage is automatic:

Use the Technique before every combat — AoE Ice DMG to all enemies with a chance to Freeze. The Frozen status may trigger additional bonus damage from A2 Trace if all enemies are affected
On Herta’s turn, use the Skill as the primary action — AoE DMG to all enemies with a bonus for targets above 50% HP. This chips enemies toward the Talent’s trigger threshold
The Talent follow-up fires automatically whenever any ally’s attack pushes an enemy below 50% HP. There is nothing to press — just watch it happen and appreciate the free AoE hits
Use Basic ATK when conserving SP. It generates Energy passively and still contributes to general damage
Use the Ultimate when Energy reaches 100. It deals AoE damage and activates the Hunter of Glacial Forest CRIT DMG bonus for subsequent attacks
In The Herta battery builds: prioritise Skill use frequency — every Skill hit contributes to The Herta’s Sticker stacks. Use Ultimate whenever available to keep rotation fast. Passkey Light Cone and Energy Regen rope accelerate this

The key to Herta: her job is mostly passive. Use her Skill and Ultimate on her own turns, and let the Talent do the rest. In teams where allies attack frequently and push enemies below 50% HP regularly, Herta fires her follow-up constantly without needing any additional player management.

Herta Ascension Materials

Credits: 246,400
Ascension materials: Ancient Part, Ancient Spindle, Ancient Engine (from Automata enemies on Jarilo-VI) and Lightning Crown of the Past Shadow
Trace materials: Key of Inspiration, Key of Knowledge, Key of Wisdom (from Bud of Erudition Calyx on Herta’s Space Station) and Guardian’s Lament (from Echo of War)
Boss material: Lightning Crown of the Past Shadow from the Stagnant Shadow domain

Is Herta Worth Using in Patch 4.3?

Yes — particularly in two specific contexts. First and most importantly, Herta is the best free 4-star partner for The Herta in Sticker-generation battery roles. Her frequent AoE hits from the Talent follow-up feed The Herta’s passive system consistently and reliably, making her genuinely valuable in Erudition dual-DPS teams even at 4-star rarity. If you have The Herta and want to run her at minimum resource cost, 4-star Herta is the answer.

Second, Herta is a strong standalone sub-DPS in Pure Fiction and multi-wave content. Her Talent’s automatic follow-up fires on nearly every ally action when enemies are at low HP, contributing AoE Ice damage that adds up to significant total output over a full fight. She is one of the best passive damage contributors available from the standard banner.

The honest limitation: in single-target boss fights or Memory of Chaos stages where enemies are at full HP for extended periods, the Talent rarely fires and Herta loses most of her value. She is a content-specialist, not a universal pick. Play her in wave content and alongside The Herta, and she delivers genuine competitive value from a standard banner 4-star character.
