Fighting Fantasy: The Warlock of Firetop Mountain Cheats :
No Lock Picking!
Go to any locked treasure chest, face it so that you see the hand on the bottom screen. Go to the character screen. (The little stick figure on the bottom right) From there, click on your bag and you will see the items that are in the chest on the left side! You can take them and use or sell them like any other item. (Make sure you see the hand on the touch screen or it won't work!)
