Wandering Sparks

Exploration Stage: Sunny Terrace
From: Inspector
Description: So the ball lightning isn’t fiction but reality? I read once about a trap for ordinary ball lightning. Maybe it’s also suitable for the black kind created in the fog? Try to find a thunder maze, and I’ll tell you how it works!
Completed: I think you’ve found the exact thunder maze I once read about! When the ball lightning hits it, it will wander along a closed route, which will greatly limit its movement. This will make it easier for Isabelle to neutralize this anomaly.
