Himeko • Nova is a Fire Erudition damage dealer built around a brand-new mechanic, the Assist Skill: any ally can spend a turn to have her giant mecha, the Starblazer, strike all enemies with Himeko's own stats. When fellow Trailblaze Companions use it, she switches to Verdict (massive Ultimate damage, best against few targets) or Decimation (huge team-wide CRIT DMG, best against crowds), then finishes the job by piloting the Starblazer with her Ultimate.

Light Cones
A Star That Lights the Night BiS

Relics

4pIncreases DMG dealt by Skill and Ultimate by 20%. After using Ultimate, additionally increases the DMG dealt by the next Skill by 25%.
Wavestrider Captain

Teams
Recommended teams
Verdict – double advance
Her most used team. Sunday and Dan Heng • Permansor Terrae both enable Verdict; Sunday and Sparkle feed her extra turns and Energy.
Decimation – Nihility core
Welt enables Decimation and, with Mortenax Blade, stacks massive DEF reduction and Ultimate DMG buffs. Mortenax's frequent AoE hits quickly charge free Assist Skills.
Budget
Accessible version: the Trailblazer (Remembrance) enables Verdict and adds True DMG, and Welt can switch her to Decimation.
Guide
How to play
How she works
- Assist Skill. While Himeko • Nova is on the field, every ally gets an Assist Skill use: the Starblazer hits all enemies (this counts as Himeko using her Skill and uses her stats) and the ally regains 4 Energy. Her A2 makes her own Assist Skills free.
- Companion Protocols. When a Trailblaze Companion other than Himeko uses the Assist Skill, she enters a state, and (A4) that ally immediately gets an extra turn in which they can use their Ultimate:
- Verdict (Trailblazer, Sunday, any Dan Heng): Himeko deals +100% DMG and her Ultimate gains another +100%. Every 2 allied Ultimates trigger a free Assist Skill.
- Decimation (Himeko, Welt, any March 7th): all allies gain +100% CRIT DMG, and Skills another +100%. Every 9 enemies hit by allies trigger a free Assist Skill.
- Skill. Refills all Assist Skill uses and grants Navigator's Semaphore for 3 turns: all allies deal +20% DMG and Himeko regains 1 Assist Skill use at the start of each of her turns.
- Ultimate (150 Energy). You pilot the Starblazer: up to 6 Hyperluminal Particle Beams build Source Energy, Orbital Annihilation Pulse spends it for extra bounces, and a Final Hit closes the combo. It has built-in overkill protection.
Rotation
- Use her Technique: she casts her Skill for free at the start of every wave.
- Have a Trailblaze Companion use the Assist Skill early to enter the right Protocol, then play their extra turn normally.
- On Himeko's turns, alternate her Skill (to refresh Assist Skill uses) and her own free Assist Skills.
- Use the Ultimate as soon as it's ready: it starts with 3 Source Energy (A6), and Pulses fired at 3+ Source Energy hit 30% harder on their bounces.
Tips
- Pick one Protocol per fight: Verdict for bosses and small waves, Decimation for large groups. Switching mid-fight is powerful but hard to pilot.
- Always bring at least one Trailblaze Companion, or she can't enter either state.
- Base SPD is recommended; 134–135 SPD works well with Sunday's action advance.
Strengths
- Excellent in AoE and strong in single-target
- Two forms that adapt to every endgame mode
- Wide pool of teammates, including free or older characters (Welt, Sunday, the Trailblazers…)
- The Trailblaze Companions tag promises long-term support
- Low skill floor, high skill ceiling
Weaknesses
- Her signature Light Cone is far ahead of the alternatives
- Dual-form teams are very hard to pilot
- Her best teammates are also wanted by other teams
