Reactor: Item Fusion Service Relaunch

Item Fusion

Item Fusion system has officially relaunched today, January 15, 2026. 

  

As outlined in our previous notice, this update introduces a new valuation model and clearer operation rules to ensure a more intuitive and stable experience. 

Please review the schedule and mechanics below before participating. 

  

 

1. Service Open Schedule 

To ensure a smooth onboarding process, the Web App interface will be open prior to enabling actual Fusion features. 

This allows maplers to explore the new UI and familiarize themselves with the changes beforehand. 

  

  • Web App Access (UI Only): January 15, 2026, 01:30 (UTC+0) 
    • The Fusion page can be accessed to view the current basket composition. 
  • Fusion Participation Starts: January 15, 2026, 05:00 (UTC+0) 
    • Actual item submission and interaction features will be enabled from this time. 

 

 

2. Mandatory Entry Quiz 

To ensure all participants fully understand the mechanics, a one-time quiz is required before their first participation. 

Participants can refer to the [User Guide] while taking the quiz. It is highly recommended to keep the guide open for reference. 

 

 

3. Round Operation Rules (Daily Checkpoint System) 

Fusion operates on a "Daily Checkpoint" mechanism. 

The system determines the progression of rounds by taking a snapshot of the Basket status at a fixed time every day. 

  

[ Daily Checkpoint Time ] 

The system checks the status once a day at 06:00 (UTC+0). 

  

[ Progression Logic ] 

At the exact Checkpoint time, the system verifies the Basket's progression rate: 

✅ Condition A: Basket is 100% Full 

The current round ends immediately. 

Rewards are settled, and a new round starts (Basket resets to 0%). 

❌ Condition B: Basket is Incomplete (<100%) 

The current round continues and is extended until the next day's Checkpoint. 

  

[ Scenario Example ] 

Here is how the rounds proceed based on the daily snapshot.  

  • Day 1 Checkpoint: Basket is 100% > Round 1 Ends & Round 2 Starts. 
  • Day 2 Checkpoint: Basket is 95% > Round 2 Continues (Extended for 24h). 
  • Day 3 Checkpoint: Basket is 100% > Round 2 Ends & Round 3 Starts. 

  

 

 

Patience and support during the optimization period are greatly appreciated.
