Link Codes
The first step players must do first is for older players to invite newer players back into Wuthering Waves by sharing their Invite Codes for the returning players to use!
This is found at the bottom-left section of the event page.
Invite Up to 3 Returning Rovers to the Game
Each veteran player can invite up to 3 Returning Rovers. Once the members are complete, they must link their accounts to the code that they used to keep track of their progress as returnees to the game.
Returning Rover Requirements
To qualify as a Returning Rover, the following conditions have to be met first.
| All Returning Player Requirements |
|---|
|
• Must reach Union Level 8 before the start of the event. • Have not logged in for 14 consecutive days immediately before the start of the event or; • Have not logged in since August 14, 2025. • Eligible Returning Players will retain their status for the rest of the event. |
Receive Spiritual Flames Based on Progress
Completing a Task will reward the player with a certain amount of Spiritual Flames. These are needed for the older players to be trated to special rewards like Astrite and Shell Credits.
There are two ways to receive Spiritual Flames: one by your progress if Returning Rovers use your code in Invitation Tasks, and the returnees' progress since coming back in Friendship Tasks!
Invitation Tasks
Invitation Tasks will reward you with Spiritual Flames depending on the effort to share your code and get others to come back using your Code. Up to 3 people can make use of it before slots run out.
Friendship Tasks
Friendship Tasks are markers for the players you invited back using your code. To claim Spiritual Flames here, the invited players must reach certain amounts of Activity points per day, which will reflect in your page.
Trade Spiritual Flames for Rewards
Once veteran players receive Spiritual Flames, they can be traded for Astrite and Shell Credits. Make sure to invite returning and let them progress consistently!
