1. Go to Amityville 2. Talk to Thursday, the girl in front of the Town Hall, and click on "The path?" 3. Choose "Crystal Clear Lake" from the choices 4. Go south (defeating monsters as necessary), turn east the first chance you get. Go east as far as you possibly can, then turn north. That will take you to Chaney's shop. Inside you can talk to Chaney. If you're going to upgrade your doom weapon, you'll need a regular doom weapon and research materials (the latter you can buy from Chaney for the price of 5000 Gold). Only then can you go back to the Mysterious Stranger outside of Falconreach with your weapon and 5 Unlucky Doom Essences to finish the upgrade. (The Unlucky Doom Essences you can get by finishing the Haunted House quest: see Artix or Thursday in Amityville to start it.)
