If you have the Silver Seed type "SERPENT MANIMAL" (this may need to
 my in lower case)
 
 Keys and effects are largely the same as from Ultima 7 part 2:
 Serpent Isle, apart from this cheat is a more user friendly version
 of the full debug mode available in Serpent Isle. The only difference
 I have heard of, is when casting a spell (F5), you are no longer
 prompted for a spell number - you must type the number, and press
 ENTER to receive it. Otherwise, just refer to the cheats/tables from
 Serpents Isle.
