The Soul Harvester is used to hold
Lingering Essence that need to be collected for the
Halloween 2009 Quest. It is obtained at
Grizelda the Hag's ruined house. Double-click the Soul Harvester on the table and one will appear in your backpack. It takes 5 Lingering Essence to completely fill the harvester. When full the bottle will glow red.
Return to Grizelda's house and use the Harvester on the alchemy table next to where you got it.
