Her ideal stats prioritize CRIT Rate, CRIT DMG, and ATK, complemented by Skill and Ultimate damage boosts. Because her kit already provides a substantial 80% CRIT DMG buff, Light Cones focusing on CRIT Rate are generally preferred.

The Herta's strong self-buffs and damage multipliers make her a formidable damage dealer. Optimal Light Cones will boost her CRIT Rate, CRIT DMG, ATK, and Skill/Ultimate damage.

Light Cone Options:

The Seriousness of Breakfast (S5)

HP ATK DEF 846 476 396

S5 Passive: Increases wearer's DMG by 24%. ATK increases by 8% per defeated enemy, stacking up to 3 times.

A serviceable, readily available option for early-game players. Provides straightforward damage boosts.

The Day The Cosmos Fell (S5)

HP ATK DEF 953 476 331

S5 Passive: Increases wearer's ATK by 24%. CRIT DMG increases by 40% for 2 turns when hitting ≥2 enemies with a Weakness.

Performance depends on consistently triggering the conditional CRIT DMG buff. A decent placeholder.

Eternal Calculus (S5)

HP ATK DEF 1058 529 396

S5 Passive: Increases wearer's ATK by 12% + 8% per enemy hit (stacks 5 times). 16% SPD increase for 1 turn if hitting ≥3 enemies.

ATK boost fluctuates based on the number of targets. Solid when fully utilized.

Yet Hope Is Priceless (S1)

HP ATK DEF 952 582 529

S1 Passive: Increases wearer's CRIT Rate by 16%. Follow-up attack DMG increases based on excess CRIT DMG (≥120%). Ignores 20% target DEF for 2 turns after Basic ATK/Ultimate use.

Provides a reliable CRIT Rate boost. Follow-up attack buff is less useful for The Herta. Consider other F2P options first.

Geniuses' Repose (S5)

HP ATK DEF 846 476 396

S5 Passive: Increases wearer's ATK by 32%. CRIT DMG increases by 48% for 3 turns per defeated enemy.

Strong ATK increase and CRIT DMG buff, but buff duration is dependent on enemy kills.

An Instant Before A Gaze (S1)

HP ATK DEF 1058 582 463

S1 Passive: Increases wearer's CRIT DMG by 36%. Ultimate DMG increases based on Max Energy (up to 64.8% at 180 Energy).

Provides a substantial CRIT DMG boost and Ultimate DMG increase. However, The Herta benefits more from Skill DMG boosts.

Before Dawn (S1)

HP ATK DEF 1058 582 463

S1 Passive: Increases wearer's CRIT DMG by 36% and Skill/Ultimate DMG by 18%. Follow-up attack DMG increases by 48% after using Skill/Ultimate (Somnus Corpus effect).

Excellent unconditional stats, boosting both CRIT DMG and Skill/Ultimate damage. The Herta cannot utilize the follow-up attack buff.

Today Is Another Peaceful Day (S5)

HP ATK DEF 846 529 330

S5 Passive: DMG increases based on Max Energy (up to 64% at 160 Energy).

Provides a substantial and unconditional damage boost, easily maximized by The Herta's high Energy cost. High base ATK. Excellent F2P option.

Night on the Milky Way (S1)

HP ATK DEF 1164 582 396

S1 Passive: ATK increases by 9% per enemy (up to 45%). DMG increases by 30% for 1 turn when Weakness Break is inflicted.

High ATK boost but requires multiple enemies and Weakness Break for optimal performance.

Into the Unreachable Veil (S1)

HP ATK DEF 953 635 463

S1 Passive: Increases wearer's CRIT Rate by 12%. Increases Skill/Ultimate DMG by 60% for 3 turns after using Ultimate. Recovers 1 Skill Point if Ultimate consumed ≥140 Energy.

The Herta's signature Light Cone; best-in-slot due to CRIT Rate boost, significant Skill/Ultimate damage increase, and Skill Point recovery. Highest base ATK among Erudition Light Cones.

This detailed comparison should help you choose the best Light Cone for The Herta based on your resources and playstyle. Remember that team composition and enemy types also significantly impact Light Cone effectiveness.
