Strengths
- “We, Too, Stride the Stars” hits every enemy on the field in one cast, so Himeko · Nova stays relevant when MoC and Pure Fiction spawn multiple targets.
- Skill “Upraise the Vanward Cresset” buffs allies’ damage for a short window—this is the spend that keeps the rotation honest.
- Talent “Of Fire and Far Faring” implants element Weakness so Break stays online off-element—good play literally shortens Ult cooldown.
- Himeko · Nova can implant or force Fire-relevant Weakness from the kit itself—Break and Toughness routes stay online even when the MoC line-up did not list Fire.
Weaknesses
- E0 without “A Star That Lights the Night” is still clearable, but the gap versus a signature copy is larger than a single eidolon for most Erudition carries—plan the cone before deep eidolon hunting.
- If Energy or Skill Points starve “We, Too, Stride the Stars”, Himeko · Nova spends turns on Basics and the kit’s advertised multipliers never show up on the combat log.
- Spamming “Upraise the Vanward Cresset” every turn without watching Skill Points strands the rest of the team—Himeko · Nova is often the SP sink.
- If “We, Too, Stride the Stars” is still offline at the end of a MoC cycle, the build is usually Energy/ERR or rotation order—not a missing CRIT roll.
Trace Priority
We, Too, Stride the Stars carries most of the kit’s damage or utility—level this first.
Of Fire and Far Faring supports the main rotation—raise after the top priority traces.
Upraise the Vanward Cresset supports the main rotation—raise after the top priority traces.
Enkindle the First Lodestar is last priority outside of filling trace materials.
Stat Priority
Skill for Navigator’s Semaphore + Assist refund → Sunday/Sparkle advance her → Ult when free Assists from ally Ultimates are spent. Keep DH-PT shields up so Assist windows stay uninterrupted.
Welt Assist applies Decimation; multi-hit allies bank Charge toward free Assists. Time Ult after Charge payouts. Prefer 135 SPD if you lack turn advance.
Always bring at least one Trailblaze Companion or she cannot enter Verdict / Decimation. Refresh Assist uses with Skill, then dump Ultimate when free Assists are spent.
