Find a dragon and cast a 'MON ZO GOR SAR' spell then press 'ESCAPE'
 to pause the game. Now whilst 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.
