Hoshimi Miyabi build guide.

Build at a glance

M0 baseline. No signature W-Engine or fixed stage modifier assumed. This is source-checked editorial guidance; no timed run or damage comparison has been performed.

Substats: CRIT Rate to 80% in combat → CRIT DMG / ATK → Avoid exceeding 100% CRIT Rate

W-Engine candidates: Hailstorm ShrineWeeping Gemini

A CRIT carry with an Anomaly resource loop

Miyabi converts CRIT Rate into Frost buildup, capped at 80% CRIT Rate for that conversion. Further CRIT Rate can still improve critical hits. Do not copy an Anomaly Proficiency main-stat plan solely because her specialty says Anomaly.

Equipment decisions

Use the baseline below, then inspect in-combat bonuses. Changing an engine can change the right slot-4 choice without changing the rest of the build.

Branch & Blade Song

Use four pieces as the baseline. Count its conditional CRIT Rate when deciding whether slot 4 still needs CRIT Rate.

Polar Metal

Two pieces complete the six-slot plan. Compare ATK alternatives using the pieces you already own before farming a replacement.

Hailstorm Shrine

If owned, its CRIT-oriented stats fit Miyabi. Recalculate slot 4 after equipping it.

Weeping Gemini

Craftable fallback. It does not replace the signature’s CRIT stats; preserve the CRIT target with discs.

Rotation and resource management

Use the six-Fallen-Frost charged attack as the decision point. EX casts grant two stacks; the Ultimate grants three. Avoid generating resources into the cap.

1. Check the stack count before committing Energy.
2. At six stacks, fully charge Shimotsuki; do not release an incomplete charge by habit.
3. Below six, use an EX or, with the additional ability active, a partner’s Disorder to finish the resource cycle.
4. Return to the partner when further Miyabi field time would delay the next useful Disorder.

Choose a resource plan

Miyabi / Yanagi / Soukaku uses Disorder to feed the loop. Miyabi / Lycaon / Soukaku instead concentrates damage around stun. Switching between them changes the hand-off timing; it does not automatically require a different disc farm.

Shiyu Defense: carry resources into the next wave

Editorial practice: if a wave is nearly finished, compare a short cleanup against spending the full charged attack. Record whether the saved charge gives a cleaner opening on the next spawn.

Deadly Assault: audit the second cycle

Editorial practice: after the opener, count how often you wait below six stacks. Adjust the partner hand-off before replacing equipment. One strong opening can hide a stalled repeating cycle.

Hollow Zero: keep one baseline

Editorial practice: keep the same loadout and record which acquired effect changes your spending decision. Do not describe that run-specific change as a permanent build upgrade.

Mistakes to catch

Watch for resource overflow, CRIT overcapping and switching to an Anomaly Proficiency disc without a specific reason. Try one correction per run so its effect remains observable.

What still needs testing

• No measured comparison of ATK versus Ice DMG slot 5 for a fixed squad.
• No boss-specific timings for the currently rotating stages.

Mode notes share the equipment baseline above. Existing mode records are retained as context links; they are not separate tested loadouts.
