Reverse: 1999 4.0 Progression Order and Artificial Somnambulism Full Stars

Applicable version: 4.0.0 "The Doorward" (updated 2026-09-24, per official version field)

Reverse: 1999 4.0.0 snapshot: environment and progression pillars

The official version field reads 4.0.0 with an update date of 2026.09.24, and the page title says "2026 Suitcase Tour Celebration · 4.0 'The Doorward' is live". A tour version is an annual-scale release, and the resources available in this window run higher than a normal patch.

What 4.0.0 changes for progression

Character power still comes from four pillars: level, Insight tier, Resonance level and Psychube . Beryl, the 4.0 tour limited unit, is an Intellect character , so investment in her build beats filling a stopgap slot; this week's stamina plan sits on gghubs.com.

What each progression pillar does

Insight is the ascension ladder — tier I, II and III — and it sets the level cap. Resonance splits into level and point layout, and it drives your stat sheet. A Psychube is an equipment slot whose level and amplification give a separate multiplier. Portray comes from duplicates .

Reverse: 1999 4.0 progression order: Insight, Resonance or Psychube first

Conclusion first: Reverse: 1999 progression order is Insight II → Resonance 10 → Psychube level → Portray, supports parked at Resonance 7. Resonance 10 gives a guaranteed stat gain, while Insight III mostly raises the ceiling, and at low investment a raised ceiling pays off less .

Main DPS breakpoints

A main DPS at Insight I level 1 wants Resonance 3, at Insight II level 1 wants Resonance 5, and at Insight II level 50 wants Resonance 7 .

Supports stay two tiers lower

Supports run two tiers below the main DPS on both Insight and Resonance, sit at Resonance 7–9 before Insight III, and do not need Resonance 10 . Saved Resonance material goes further on the next DPS.

When to touch Portray and Psychube amplification

Duplicates go into Portray rather than being burned as fodder . Push the main DPS Psychube's level before amplification, because a correct resonance layout returns more early on.

Reverse: 1999 4.0 Resonance and Psychube: how to split resources

Resonance level sets how many points you can place, and the layout decides whether they land on attack, crit or HP; at equal investment a wrong layout leaves a large stat gap . A DPS and a support cannot share one layout.

Resonance layout choices

Fill the attack and crit nodes on your DPS first instead of spreading points evenly, and let supports cover survival and utility; per-slot picks shift between patches, so follow the in-game screen . Never merge Resonance materials upward, because merging loses value .

Psychube level before amplification

The first 6-star Psychube costs 210 shop currency, and the Psychube stage has 7 floors with 2 free runs a day . High floors make the first copy land inside a week, so skip Psychube EXP purchases. Psychube follows Resonance because Resonance lifts the whole team.

Reverse: 1999 4.0 materials and shops: where to save

Three rules cover it: farm Insight materials on demand, never merge Resonance materials, and spend shop currency by expiry risk .

Which Insight stage to farm

Odd Insight floors drop 1–2 scrolls at random while even floors drop a fixed 2 , so farm even floors when short and cut the randomness.

Shop priority order

Weekly-refresh items beat discounted ones, because discounts are long-term stock that never rotates out, while monthly-refresh items should be cleared first . In the Dream Record shop, Resonance Crystal cases top the list.

Reverse: 1999 4.0 Artificial Somnambulism: Deep Sleep vs Dream domain

Artificial Somnambulism is the recurring high-difficulty mode, split into the Deep Sleep domain and the Dream domain; full stars require clearing inside the turn limit around the environment's buffs and debuffs . In 4.0 the Deep Sleep domain returns to a monthly cycle .

Progress carries over

After a full-star Deep Sleep clear the next cycle can start at "Deep Sleep Fragment V", and with every A-grade certification in the Dream domain at "Dream Fragment III" .

Three conditions for three stars

Turn count comes first: short damage runs you out of turns. Survival comes second, since supports absorb the debuff pressure. Environment fit comes third, and the cycle's buffs or cuts decide between a DPS and a utility slot . Enough investment but the wrong element still leaves you a star short, so take the clear, then survival, then turns .

Element-focused teams

Single-element teams stacking same-colour buffs are the 4.0 favourite, and a Beast double-DPS line trims turns in a matching environment . The cost is swapping teams against a countered element, so keep two ready.

Reverse: 1999 4.0 turn pacing and common mistakes

Turn pacing decides Artificial Somnambulism: at equal investment a good rotation saves one or two turns, while a bad one times out . The step a reverse 1999 beginner guide skips most often is reading the current buff before the first skill.

How to lay out turns

Two turns of buffing, then the damage window from turn three, with the last turn for cleanup. Wake-up mechanics need stacking early, and the Dream domain has run a buff like "+5% Wake-up after an enemy leaves the field" . The order community players verified in testing is to read the boss mechanic first.

Four common mistakes

1. Putting every support point into damage, then folding when the debuff lands.
2. Racing for damage early and leaving the burst window unbuffed.
3. Running one team through every floor without swapping element.
4. Merging Resonance materials upward and losing a tier.
