If you want to ensure you get your hands on this unique weapon skin before time runs out, here is a breakdown of how the event works and the exact steps you need to take to unlock it.

Quick Event Overview
Item Name: fromis_9 Light Stick weapon skin (The "Flo-bong" skin).

Type: Purely cosmetic visual transformation. It looks incredible, but it does not alter your combat stats or provide any gameplay advantages.

Availability: Limited-time milestone reward. Once the event ends, it is gone for good.

End Date: August 12, 2026.

Step-by-Step Guide to Unlock the Weapon Skin
Unlocking the skin requires grinding through the collaboration content rather than relying on random drops or pure luck. Follow this roadmap to secure yours:

Access the Event System
First, log into Aion 2 during the collaboration period. Open up your main Event menu from the interface. This is where you will track your active crossover content, milestones, and progress points.

Complete "The Case of the Stolen Stage Props"
This is the core gameplay loop for the event. You will need to complete a special event questline titled "The Case of the Stolen Stage Props" (sometimes translated in-game as "The Stolen Performance Props").

Head over to the specially designated fromis_9 Collaboration Stage zones located in major towns like Verteron or Altgard.

Speak with the event NPCs stationed there to pick up the missing property missions.

You will need to explore the map, defeat specific designated targets, and interact with objectives to track down and recover the missing concert props.

Advance Through the Collaboration Track
Every time you return stolen props and clear tasks for the event NPCs, you earn progress points toward the event reward track. The track is broken down into tiers:

Early Stages: Grants basic event upgrade materials and promotional currency.

Mid Stages: Unlocks exclusive emotes, including character choreography pulled straight from fromis_9's track "LIKE YOU BETTER".

Final Stages: Reaching the final milestones or completing the ultimate quest in this specific storyline rewards you with the fromis_9 Light Stick weapon skin.

Additional Collaboration Collectibles
While you are working your way toward the Light Stick skin, there are several other limited-edition cosmetics worth keeping an eye out for. NCSoft introduced a handful of other themed items in this update that let you fully lean into the crossover aesthetic:

Idol Outfits: These are replicas of the exact outfits worn by the group members in their promotional videos. Equipping a full set actually transforms your character's likeness into fromis_9.

Four-Leaf Clover / Flover Wings: Beautifully designed, themed cosmetic back attachments that match the group's official fandom identity.

Exclusive Pets: You can pick up two adorable cosmetic companions during the event—the "Baby Flomeow" (also called Baby Flonyang) and the "Flostick" pet.

Make sure to pace your questing so you can gather enough progress points before August 12, 2026.
