Find a dragon and cast a 'MON ZO GOR SAR' spell then press 
"ESCAPE" to pause the game. Now while holding down the 
left 'ALT' key type in: 'LORD LIBRASULUS SMITHES THEE DOWN' 
(with spaces). Unpause the game and kill the creature, now 
when the dragon dies it should leave behind a Firestaff and 
the party should also be invincible.
