## Event Schedule

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

| Region                | Closes                | Timezone |
| --------------------- | --------------------- | -------- |
| **Asia**              | May 14, 2026 at 12:00 | UTC+8    |
| **Americas / Europe** | May 14, 2026 at 12:00 | UTC-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:

| Reward                   | Use                                                  |
| ------------------------ | ---------------------------------------------------- |
| **Oroberyls**            | Premium currency for headhunting and store purchases |
| **Mark of Perseverance** | Event-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**:

| Slot      | Input                                     |
| --------- | ----------------------------------------- |
| Reagent A | **Heavy Xiranite**                        |
| Reagent B | **Precipitation Acid**                    |
| Machine   | **Reactor Crucible**                      |
| Output    | **Liquid 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.

## Recommended Play Order

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.
