Here's a trick for the classic game, Quest for Glory 2: Trial by Fire by Sierra On-Line. This
trick enables you to get all the money you desire. You'll lose all the money near the end
of the game, but spend all you want until them. All you do is visit the Dervish at the desert
oasis. Get some of his beard off the tree. Return to Shapier and go to the Magic Shop.
Sell the Beard to the shop keeper for money. You can repeat this as many times as you
want, without getting more beard.
