Reverse: 1999 4.0 overview: what the patch adds
4.0 is a main-story patch with two six-stars, one four-star, one six-star Psychube and three new systems named Rift Wonderland, Bygone Portraits and Thames Silhouette, alongside activities including Friday Imp, Little Monster Dominoes, Mane's Bulletin and Focus Flashback .
The three new systems are not the same thing
Rift Wonderland and Bygone Portraits lean toward progression and daily play, while Thames Silhouette is a gameplay addition . All three unlock gradually rather than all at once, so there is no reason to clear them on day one.
The two most valuable welfare items
A guaranteed new six-star and a self-select six-star Euphoria character are both deterministic . The guaranteed new six-star is a free character you do not own, and the self-select is targeted reinforcement; both beat the expected value of a 40-pull sign-in.
Reverse: 1999 4.0 Red Arrow and Drake: gap decides order
The difference between the two is afflatus: Red Arrow is Star and Drake is Beast . Afflatus drives the counter system, so "who first" is really "which damage afflatus does my roster lack".
Star gap means Red Arrow first
Star afflatus is frequently the only clean answer in high-difficulty stages, because the counter relationship sets the damage multiplier . If your six-star roster holds only one or two Star characters, Red Arrow takes priority.
Beast gap means Drake
Beast afflatus usually leans toward damage and pressure, so an account missing Beast gains more directly from Drake . Accounts missing neither should put resources into the Psychube and wait for 4.1.
Concretely, an account with three Star six-stars already has redundancy, while an account with a single Star six-star is one counter away from being locked out of a stage. That asymmetry is why afflatus gaps should be measured as counts, not impressions: list your six-stars by afflatus, count each group, and build the character whose group is smallest. The same table tells you whether Drake is needed at all, and it stops you from spending on a banner because the trailer looked good.
Reverse: 1999 4.0 Psychube: who gets Storm's Ridge
Stand Upon the Storm's Ridge is the patch's only six-star Psychube . A Psychube is a multiplier attached to a character, so it belongs to whoever carries the largest damage share, not to the newest pull.
Psychube before levels
The same resources buy more on a Psychube than pushing a character from level 60 to 70 . Levels grow linearly while a Psychube multiplies, so the order is usable level, then Psychube, then more levels.
Never put it on a support
Support damage share is low, so a Psychube on a support wastes the multiplier . Unless its secondary stat patches a gap you have, give it to the main carry.

Reverse: 1999 4.0 Insight and Resonance: where materials go
Insight and Resonance are separate lines: Insight unlocks skills and passives, Resonance raises the sheet . Push the main carry's Insight to the current cap, then Resonance, and only then support Insight.
The Insight 3 gate
Insight 3 usually needs patch-specific high-tier materials, and those come mainly from event shops and weekly content . Clearing the event shop first beats farming weeklies, because the shop has a deadline.
Resonance value
Resonance adds sheet stats, which is a finishing touch rather than a breakthrough . Until Insight is capped, Resonance stays behind it.

Reverse: 1999 4.0 Rift Wonderland: daily routine
Rift Wonderland is one of the three new 4.0 systems . It is daily content whose output scales with time spent, so it belongs in a small daily block rather than a single end-of-week session.
Ten minutes a day
Run Rift Wonderland together with Mane's Bulletin in the same login . They share the same rhythm: daily caps and no retroactive compensation.
Order activities by deadline
Friday Imp, Little Monster Dominoes and Focus Flashback are event content with their own windows . One rule applies: shortest window first.
Reverse: 1999 4.0 FAQ
Which of the two six-stars first?
Check afflatus: with only one or two Star six-stars, build Red Arrow; missing Beast, build Drake; missing neither, park resources on the Psychube for 4.1 .
How to use the guaranteed new six-star and self-select Euphoria?
Use the guaranteed new six-star on a character you do not own, and the self-select on targeted reinforcement; both are deterministic and beat a 40-pull sign-in's expected value .
Who gets Stand Upon the Storm's Ridge?
The main carry with the largest damage share, not a support, since a Psychube is a multiplier .
Insight or Resonance first?
Insight first. It unlocks skills and passives, while Resonance only adds sheet stats .
