River Runs Deep Mini World Change/Spoiler

Messages
World Board: The river in Zao Steppe runs deep, there may be more fish than usual!

Towncryer: Hear ye! Hear ye! In Zao Steppe the river runs deep. If you catch a strange fish it is yours to keep.

Method
The dried up river in the Zao Steppe will run. During this time you will have the chance to catch several Sandfish.

When fishing a Sandfish you will earn the achievement Desert Fisher. It might take some time before you catch one, though. Consider hotkeying your Fishing Rod to make the Fishing go quicker.
