[About]
A team of Royan herders has run into trouble while guiding their Exoswarm across the frostlands. Now, they need your help to track down the strays.

[Eligibility]
Reach Union Level 14 and activate the Resonance Nexus in Startorch Academy during the Main Quest "What Burns Beneath Frostlands" to unlock.

[Event Rules]
During the event, "Migration Mayhem" stages unlock daily and come in Easy and Hard difficulties. The Easy and Hard levels include 1 and 2 lost Exoswarm respectively.

You and the Exoswarm will take turns to move in the game. You may place the Royan Shepherd's Staffs in the frostlands as barriers, use terrain features such as sinkholes and ice walls to restrict the Exoswarm's movement and surround them, and guide the lost Exoswarm back to the migration pack.

Fully surround the Exoswarm to complete the stage. Upon completion, you will receive rewards such as Astrites and upgrade Materials. Your personal record will be logged as the minimum number of Shepherd's Staffs used during each challenge.
You fail the challenge if you fail to surround the Exoswarm before they escape the current frostlands area and cause them to be lost in sight. You will need to reattempt the stage.

You may repeat each stage after its first completion. You can retry challenges as many times as needed to refresh your personal record.
