Cephla Lake Cave Surface Cave

In-game Description

You can find two NPCs right outside the cave, Domidak and Prissen. Speaking to them will begin the Misko’s Cave of Chests side quest. Inside the cave are a bunch of chests, but only a single one will contain actual treasure.

To find the right one easily, give the dog just outside some food, until it goes inside and lays down in front of the correct chest. Doing this will give you the Ember Trousers, as well as a note in a bottle that starts the Misko’s Treasure: The Fierce Deity side quest.
