1. 1

   Meet the gate first

   You need Union Level 22 and the Four Chime Shaftpost activated during Chapter IV Act I "The Wind Before the Storm." Clear that quest step before September 10 so the event is playable the hour it opens.

2. 2

   Work the Surface Layer

   Seven Surface Layer stages unlock gradually. Each one you clear opens its matching Deep Layer stage, so the Surface run is the spine of the whole event.

3. 3

   Equip Dorothy’s Companions

   Inside the challenge you pick "Dorothy’s Companions" as Support Echoes, which sharply raise your Resonators’ combat numbers. More of them unlock as you push deeper, so revisit your loadout between stages.

4. 4

   Clear the Deep Layer

   The seven Deep Layer stages are the harder mirror of the Surface set, with a wider enemy mix the further in you go.

5. 5

   Finish with the boss rush

   Clearing every Surface Layer stage unlocks the Abyss of the Final Dreams, a boss-rush challenge that caps the event.

6. 6

   Bring a friend if it stalls

   Every stage can be played in Co-Op Mode with other Rovers, which is the simplest fix for a wall you cannot solo.

• ▹Reach Union Level 22.
• ▹Activate the Four Chime Shaftpost during Main Quest Chapter IV Act I "The Wind Before the Storm."

• This one starts late — September 10 — and ends September 29, so it has the tightest window of the six 3.6 events. Do not leave it until the last weekend.
• Clear Chapter IV Act I "The Wind Before the Storm" up to the Four Chime Shaftpost now; the unlock is the part most likely to cost you a day.
• Rebuild your Support Echo loadout every few stages — Dorothy’s Companions keep unlocking as you progress, and the early set is not the best set.
• Co-op is available on all 14 stages, so a stage that is too hard solo is a matchmaking problem rather than a build problem.
• Surface Layer first, always: each clear unlocks a Deep Layer stage, and clearing all seven is what opens the Abyss of the Final Dreams boss rush.
• Astrite x600 here plus x1,200 from Resonance Sim Realm is most of the version’s event pull income — bank both before Phase 2 pulls.

Only the Astrite total (x600) is published ahead of the event; Kuro lists the remaining four items without quantities in the Rewards Overview.
