Unlimited Silver Keys:
     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. Then, do a hero
save  and then load the saved game again. You should appear out of the
Rose  Cottage  area.  You can repeat this as many times 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.

Stay Big from Bersek
     You can become permanently hugh like berserk by doing the following:

1) Get the spell
2) Cast Berserk
3) Save your cast
4) Reload the game after you cast the spell, Volia, you are now
the hulking hero you always wanted to be!

     If  you  cast  Berserk  again after using this technique, when it
wears off you will return to normal size.
