Himeko Nova's Best Light Cone

The percentage numbers listed showcase the relative DPS increase when you take into account both the Light Cone Effect(s) and Cone Base Stats.

A Star That Lights the Night (S1)
100%

Increases the wearer's ATK by 40.0 / 50.0 / 60.0 / 70.0 / 80.0%. If there are 2 "Trailblaze Companion" characters in the team, the wearer ignores 20.0 / 25.0 / 30.0 / 35.0 / 40.0% of the target's DEF when dealing DMG. When the wearer uses an Assist Skill, they gain the "Safe Escort" state, lasting for 2.0 turn(s) and stacking up to 3.0 time(s). Each stack of "Safe Escort" increases Assist Skill DMG by 20.0 / 25.0 / 30.0 / 35.0 / 40.0%. When "Safe Escort" reaches 3.0 stacks, each stack of "Safe Escort" increases Ultimate DMG by 60.0 / 75.0 / 90.0 / 105.0 / 120.0%.

Himeko • Nova's signature Light Cone and her strongest overall option. It performs best in the Verdict setup and remains her BiS choice. Early testing suggests it may be slightly weaker in Domination, though it still outperforms other options.

Into the Unreachable Veil (S1)
79%

Increases the wearer's CRIT Rate by 12.0 / 14.0 / 16.0 / 18.0 / 20.0%. When the wearer uses their Ultimate, increases the wearer's Skill DMG and Ultimate DMG dealt by 60.0 / 70.0 / 80.0 / 90.0 / 100%, lasting for 3 turn(s). After the wearer uses their Ultimate, if this Ultimate consumed 140 or more Energy, recovers 1 Skill Point.

Sources: Event Warp (limited)

A strong premium alternative that trails the signature option but remains one of Himeko • Nova's best damage-focused Light Cones.

Night on the Milky Way (S5)
77%

For every enemy on the field, increases the wearer's ATK by 9.0 / 10.5 / 12.0 / 13.5 / 15.0%, up to 5 stacks. When an enemy is inflicted with Weakness Break, the DMG dealt by the wearer increases by 30.0 / 35.0 / 40.0 / 45.0 / 50.0% for 1 turn.

Sources: Stellar Warp

Performs very well when its conditions are met. However, it requires she Breaks frequently, which she is able to achieve in scenarios such as Pure Ficiton.

Today Is Another Peaceful Day (S5)
72%

After entering battle, increases the wearer's DMG based on their Max Energy. Each point of Energy increases DMG by 0.2 / 0.25 / 0.3 / 0.35 / 0.4%. A max of 160 Energy will be taken into account for this.

Sources: Nameless Glory

One of the stronger 4-Star options available to Himeko • Nova, providing consistent damage without requiring specialized team building.

Before Dawn (S1)
71%

Increases the wearer's CRIT DMG by 36.0 / 42.0 / 48.0 / 54.0 / 60.0%. Increases DMG dealt by the wearer's Skill and Ultimate by 18.0 / 21.0 / 24.0 / 27.0 / 30.0%. After the wearer uses Skill or Ultimate, gains "Somnus Corpus." Upon triggering a Follow-Up ATK, consumes "Somnus Corpus," and increases DMG dealt by Follow-Up ATK by 48.0 / 56.0 / 64.0 / 72.0 / 80.0%.

Sources: Event Warp (limited)

A poor CRIT-focused alternative that remains close to other free options.

Himeko Nova Build Comments

Himeko • Nova deals damage from her Ultimate and Assist Skill, an ability that replaces a character’s turn with her action. However, with Astral Express members, Himeko is able to deal this action and give them their turns, incentivizing playing them with her.

Additionally, when she uses her Assist Skill on certain AE members, she will trigger different effects, with each providing an additional way of triggering more Assist Skills passively. Mixing and matching these stances is optimal for maximum damage.

While her Ultimate contributes meaningful damage, Assist Skills remain a major source of her overall output. Because of this, Energy Regeneration Rope options generally provide less value than standard offensive choices in current Verdict calculations.
