[Alliance Mission] Expedition Mission - Erda Surge

Watch out for the Erda Surge in the World's Sorrow.

- While fighting monsters in the World's Sorrow, there is a small chance that an Erda Surge will crash down on the area. When you see signs of an Erda Surge, hide under something sturdy. Monsters may appear to destroy your shelter, so don't let your guard down. You cannot enter when an Erda Surge is in progress.
