  • Story gate: Side mission unlocks after main mission [Chapter II Process V: Where Friendship Was Made]

Event Schedule

The Curious Use of Xiranite event closes alongside the version update, so the deadline is the same across all regions.

RegionClosesTimezone
AsiaMay 14, 2026 at 12:00UTC+8
Americas / EuropeMay 14, 2026 at 12:00UTC-5

End-of-event timing is tied to the start of version maintenance, so plan submissions and exchange runs before the maintenance window begins.


Participation Requirements

To unlock event content you need to reach the Test Area in Wuling:

  1. Complete the main story mission [Chapter II Process V: Where Friendship Was Made].
  2. This unlocks the side mission [Spring’s Return I].
  3. Inside that side mission, complete the objective [Enter the Test Area].

Once you’ve entered the Test Area, event missions become available and the rest of the loop opens up.


Event Rewards

Completing event missions during the run rewards:

RewardUse
OroberylsPremium currency for headhunting and store purchases
Mark of PerseveranceEvent-specific advancement material

Expect additional minor drops and craft components from TP Points and Protocol Crates inside the Test Area.


Where to Go: The Test Area

The Test Area sits inside the Wuling region. During the event window, the area receives several gameplay overlays:

  • Event-tagged missions scattered around the zone
  • TP Points that can be unlocked for fast travel and reward triggers
  • Protocol Crates to open for materials and event currency
  • Superactive Blight masses gating certain pockets of the map

Treat the Test Area as a self-contained mini-zone — clear it methodically rather than rushing a single objective, since the cleanup chain is what produces most of the rewards.


Superactive Blight & Liquid Heavy Xiranite

Some Blight in the Test Area is classified as Superactive Blight. Standard cleanup methods are inefficient against it. Instead, the event introduces a dedicated solvent:

Liquid Heavy Xiranite — spray on Superactive Blight masses for significantly faster cleanup.

Stockpiling Liquid Heavy Xiranite before each Test Area run is the single biggest quality-of-life lever for the event. Empty inventories will slow you down or force you back to the factory mid-clear.

Production Recipe

Produce Liquid Heavy Xiranite at your AIC factory using a Reactor Crucible:

SlotInput
Reagent AHeavy Xiranite
Reagent BPrecipitation Acid
MachineReactor Crucible
OutputLiquid Heavy Xiranite (containerized)

Factory Setup Tips

  • Pre-stage Heavy Xiranite and Precipitation Acid storage before the event opens so the Reactor Crucible never idles.
  • Batch output containers — Liquid Heavy Xiranite ships in containers, so plan output buffers / logistics belts accordingly.
  • Run multiple Reactor Crucibles in parallel if you intend to clear Superactive Blight in a single play session rather than across several days.
  • Top up between sessions rather than waiting until you run out mid-Test Area.

A clean run through the event roughly looks like:

  1. Unlock the gate: finish Chapter II Process V → Spring’s Return I → Enter the Test Area.
  2. Set up production: queue Heavy Xiranite + Precipitation Acid → Reactor Crucible → Liquid Heavy Xiranite containers.
  3. Visit the Test Area: unlock TP Points first to lock in fast travel inside the zone.
  4. Spray and clear: hit Superactive Blight masses with Liquid Heavy Xiranite to open new pockets of the map.
  5. Open Protocol Crates: prioritize crates as they appear — most event missions are tied to them.
  6. Loop until missions complete: keep returning between factory restocks to finish remaining objectives before the May 14 maintenance.

Final Notes

Because the event ends precisely when the next version’s maintenance begins, the practical deadline is earlier than the listed time — server downtime starts at the cut-off, so finish exchanges, claim rewards, and submit any pending event currency well before 12:00 server time.
