This trick requires a spade. First, take the Hobbe Cave Quest and go to the Rose Cottage. Walk to the circle of flowers near the house. Use your spade and dig up a Silver Key. You can also get 500 gold each time you do this if desired, by cutting the thorns and opening the treasure chest; however, you will get Evil points. Do a hero save, then load the saved game again. You should appear out of the Rose Cottage area. You can repeat this process as much as desired. If you want to get unlimited keys throughout the game, do not finish the quest. You can keep going back and getting the Silver Key.
