October 20 new features and optimization guide

After October 20, unlocked Records at level 21 or higher can be edited once for potential and once for notes.

Confirmed edits cannot be undone and materials are not refunded.

Lower an acquired normal potential by one level to redistribute one free point, up to five points; its minimum level is one.

Core and unacquired potentials are excluded.

Confirmation costs one fine brew.

Reducing an elemental note yields one free note, up to 15 to redistribute within a 0–99 range per element; linked skill levels change accordingly.

Confirming note edits costs one echo of all sounds.

Vita can operate quick battles.

Configure potential priorities, shop spending and event choices from difficulty selection.

Commissions continuously spend tokens and can be stopped with pause.

Refill with token supplies or Stellanite Dust; supplies come from daily missions or the shop.

In certain difficulty-eight events, failing the 650-Stella-Coin choice raises the chance on its next repeat, with success guaranteed on the third attempt.

Nanoha gains higher normal/main-skill damage, an interruption-resistant second sunflower projectile and clones lasting 25 seconds instead of ten, with normal-potential improvements.

Race gains main-skill/potential damage and area damage on tracking lasers.

Gerie gains attack, skill and core-potential improvements; her ultimate produces three giant chain spears instead of one.

Minerva receives potential-effect and description adjustments.

Chixia gains main-skill damage and interruption immunity while her shield lasts.

No unstated multipliers have been supplied.

The returner campaign is for accounts inactive for at least 30 consecutive days before maintenance began on October 20, 2026 at 12:00.

Open it after returning; it cannot be reactivated within 40 days and ends at 04:59 on the fourteenth day from return.

First entry grants 500 Stellanite Dust and three Energy Drink Bottles.

Seven-day cumulative login and return missions give further materials.

Special wanted missions provide up to 80 additional rewards for participating in wanted trials.

Six temporary trial Records covering every element can be used in listed combat modes.

Their level scales with Authority Level; they cannot be dismantled and are removed when the event ends.

A separate paid seven-day returner offer gives a total of 1,200 Stellanite Dust and 28 Energy Drink Bottles with purchase and seven login days: 300 Dust/four bottles on day one, then 150 Dust/four bottles daily.

Remaining unclaimed or locked rewards are mailed after the sale period.

No price is listed.

Authority Level cap rises from 40 to 60; experience earned at the old cap before the update is not retroactively banked.

Full Vigor starts overflow storage at one point per 18 minutes, capped at 2,400.

Past limited-event stories gain replay and first-clear rewards.

All six Chaos Arena elements gain difficulties 21 and 22 and remain open around the clock from the October 20 update until November 10 at 11:59.

The notice body also confirms Chitose and Shia joining permanent recruitment.

Badge Trial gains difficulty four and selectable reward pools.

Its sacred-dew fragments can be exchanged in the badge-material shop unlocked at Authority Level 32.

At level five, retrospective and encore-recruitment missions offer dew, badge polishers and exchange certificates.

Certificates exchange for previously acquired limited-event five-star Records, up to five exchanges per Record.

Unowned Records and items already fully exchanged in their original event shop cannot be redeemed again.

Settings → Game lets players choose default damage numbers, combined numbers or no numbers.

After clearing Monster Surge on hard mode, Disaster Frontier adds automatic selection to destiny-card screens at any difficulty.

These are display/control improvements, with no additional rewards stated.
