Why structure before raw stats
4.0 building has four layers: Insight, Psychube, Resonance and Portray. Insight sets skill unlocks and base stats, Psychubes set damage structure, and Resonance and Portrays are late-game reinforcement . Structure comes first because structural gains are multiplicative and stat gains are additive, so the same materials show up faster in structure.
Reverse: 1999 4.0 Psychubes: pick by role, not by stat line
The test for a Psychube is not which one has the bigger stat line but whether it amplifies that character's core mechanic .
Damage dealers
For damage dealers the order is: an amplification that triggers the core mechanic first, then flat stat amplification, then generic crit pieces. Flat stats rank second because in high-difficulty content a mechanic-triggering amplification opens a bigger gap .
Supports and healers
Supports want Psychubes that give the team damage or damage reduction, and healers want ones that raise healing or add shields . Their payoff does not show on the panel but in how much room the team has to make mistakes, so judge it in practice rather than by intuition .
Reverse: 1999 4.0 Resonance: which direction to push
Resonance supplies stat reinforcement, and the point is covering weaknesses rather than stacking the ceiling .
Damage dealers
Cap the ATK, crit and damage bonus nodes first, then consider survival. Do not max everything: Resonance materials are heavy in 4.0, and maxing one character costs enough to bring two supports online .
Supports and healers
Supports push survival and effect hit, healers push HP and healing efficiency . Their Resonance goal is not damage but surviving a high-difficulty burst without being wiped .
Reverse: 1999 4.0 teams and Dream runs
Dream runs refresh weekly and are cyclical high-difficulty content, so teams follow the current enemy elements and mechanics rather than one fixed line-up .
| Team type | Line-up | Roles | Substitutes |
|---|---|---|---|
| Element counter | Main DPS, sub-DPS, healer, flex | Pick the main DPS for the enemy element | A well-built generic unit if you lack the counter |
| Mechanic answer | Main DPS, two supports, healer | Supports cover the current mechanic | Swap in same-role supports |
| Safe full-star | Main DPS, support, healer, sustain | Trade ceiling for consistency | Good for high-floor attempts |
How to sequence the floors
Read the enemy elements and mechanics first, then choose the team; each week clear the floor you can full-star and then climb. The order holds because retrying a high floor costs far more time than one more low-floor run . Because the mode refreshes weekly, a team tuned for one cycle may not fit the next, so keep at least one flexible well-built unit in reserve .
Psychube versus Resonance payoff
The same character clears better with Psychubes finished and Resonance partial than the reverse . Psychubes shape damage structure while Resonance raises the stat floor, so adding stats to wrong structure compresses the return.
Reverse: 1999 4.0 Portray decisions
Portrays come from duplicate characters and are late-game reinforcement.
| Priority | Item | Reason |
|---|---|---|
| 1 | Main DPS Psychube | Multiplicative structure, most direct gain |
| 2 | Key main DPS Portray | Breakpoint tiers first, not every tier |
| 3 | Supports at Insight II | Unlocks function at lower cost than chasing the ceiling |
| 4 | Generic Resonance stock | Covers new characters after updates |
Should you chase Portrays?
The precondition is that the main DPS Psychube and skills are already done. Chasing Portrays before the Psychube is set adds stats to an incomplete structure, which dilutes the return . For 4.0 character strength and teams, check the Reverse: 1999 tier list, and new players should use the Reverse: 1999 beginner guide to clear the story and basic resources first.

Where stamina goes
Stamina goes to story progress and Insight materials first, with Psychube materials saved until the main DPS clears its Insight stage . Insight is the gate and the Psychube is the structure, so skipping the gate wastes the structure.

Should I do Psychubes or Resonance first?
A: Psychubes first. They give multiplicative structure gains while Resonance is closer to linear .
