All non-quest items are random.
If the quest is to get an item in the possession of a specified entity, that entity is ALWAYS on the bottem level of a dungeon. The small third level.
If the quest is just to get an item, the item is ALWAYS just lying on the floor on the bottem level.
Due to some bugginess occasionally an item or entity isn't there even if you try every dungeon and the quest has to fail.
