This Reverse: 1999 tier list style breakdown sets the 4.0.0 build order: whether core units or fillers come first, how to split resources between Psychubes and levels, the 2026-10-15 self-select banner plus the rerun window closing, and the priority order for the Night of Refrains and Boxed Friendship reward lists. The version number comes from the official site field, while banner and reward values follow official notices.
Applicable version: 4.0.0 "Gatekeeper" (live 2026-09-24)
Reverse: 1999 4.0 Overview: Gatekeeper And The Box Parade
Version number and update date
The official site version field lists 4.0.0 with an update date of 2026-09-24 and the celebration titled 2026 Box Parade . New system units and Insights arrive in waves after an update, so plan builds around how many waves a version ships rather than treating it as a single drop.
Which systems this version locks in
4.0.0 phase one shipped the Insight system alongside the limited SP Crossbow, with 37 as that system's core Insight unit; Beryl takes a Passion rotation route, while Centurion and Matilda cover the displacement system and a lower-tier Afterglow support . System content only fires when the key units are together, which is why core units come first.
Reverse: 1999 Build Order: Core Units Or Generic Fillers
Core first
A system core converts teammates' actions into value. Drake, for example, is positioned as an Afterglow sub-DPS who does not consume card slots and chases automatically . Not consuming card slots means he coexists with other damage dealers without forcing you to rebuild the whole rotation, so his marginal value sits well above an equal-level generic replacement.
Fillers second
Generic units slot into any team, which is also why they are optimal in none. When resources are tight, finish one system before opening a second (rationale: completed systems multiply, generic fillers only add).
Reverse: 1999 Psychubes And Levels: Where Resources Go
Psychubes and levels do different jobs
Levels supply base stats, while Psychubes usually change how a unit's mechanics perform . For the same tier of investment, mechanic changes move real results, so Psychubes outrank piling on levels.
When levels are worth chasing
Levels and Insight pay off once the key mechanics are online but a stat threshold still blocks you (rationale: mechanics before stats). Levels matter, they simply queue behind mechanics.
Reverse: 1999 October Banner Window: Self-Select And Rerun Closeout
The dates
2026-10-15 is this version's switch point: Drake arrives as a standard new 6-star Beast unit, and the "Muddy Heart Retrospective" self-select banner opens with Qu Xiang, Liang Yue, Nana, Lucy and Nodika available; Beryl's rerun closes its 2026-09-25 to 2026-10-15 window .
How to use a self-select banner
A self-select banner exists to plug holes in your older roster. The test is whether the gap is a system core: if you are missing the unit that makes a whole system run, it outranks completing a collection (rationale: core units generalise better). Pity rules on rerun banners follow official notices, so confirm them before pulling.
Reverse: 1999 Reward Lists: Night Of Refrains And Boxed Friendship
The sixteen prizes in Night of Refrains
Night of Refrains offers 16 prizes including a Curious Invitation (random unowned 6-star), a Travel Keepsake (standard self-select 5-star), 5 pulls for SP Crossbow, 5 pulls for Drake and 500 Clear Drops . The random new-6-star invitation carries the most value, so hold it until you have confirmed your gap.
Boxed Friendship and the free jukebox
Boxed Friendship lets you pick one 4.0.0 standard Insight 6-star, while the free jukebox provides an 880 Clear Drop voucher and 7 pulls among other rewards . These rewards live on event pages and expire, so claim first and plan later.
| Priority | Action | Reason |
|---|---|---|
| 1 | Claim Night of Refrains and Boxed Friendship | Event pages expire |
| 2 | Identify the missing unit in your Insight or Afterglow system | An incomplete system idles even a strong carry (rationale: system triggers) |
| 3 | Psychubes before levels | Mechanic value beats raw stats |
| 4 | Pull a self-select banner for gaps, not for a collection | Core units generalise better (rationale: as above) |
Phase two banner and rerun schedules for 4.0.0 follow official notices, as do claim windows for in-version event rewards. Version switches make check-in and event-page rewards easy to miss, so anchor those claims to your first login each day through October.
One more timing note: the 2026 Box Parade celebration opened with 4.0.0 on 2026-09-24, and phase two banners plus reruns follow official notices, so confirm exact dates in game before pulling . Event-page rewards do not carry across a version switch, which is why claiming first beats planning first.More Reverse: 1999 guides on gghubs.com.
