Operencia: The Stolen Sun

While playing through the story Kela will join your party. You will get her hammer, Stoneheart, at Deva Fortress. Fast travel to the Great Forest and go into the cave that is just East of the Hungry Plant on the map. While in the cave fix the broken bridge with Stoneheart and defeat the skeletons; they will drop a “stinky boot”. Feed the boot to the Hungry Plant and it will spit out a chest.
