you need to have reinforced cell with diabosite, I think a item that can attract the werewolf, for that, talk to the witch at night, and she will help you giving you a recipe for a item that attracts werewolfs, then just retun to forest at night with the item, find then, fight them or seduce them, I guess, until they are almost finished, use the item as many time as possible, like 10 times, defeat them and they will be at your dungeon in your house.
