Down the Drain Mini World Change/Spoiler

Messages
World Board: ''The river south of the outlaw camp is flooding. A small island there should now be reachable safely.''

Towncryer: Hear ye! Hear ye! A river is flooding, south of the outlaw base. Explore a new isle, an unknown place. Don't be afraid, but ready your blade.

Method
This change is to the south of Outlaw Camp.

A new island becomes accessible containing a spawn of 11 Water Elementals. Kill 50 of them in the dungeon to receive the achievement Down the Drain.
