Hints

Dupicate Iitem:
Must be in a mutiplayer game with at least one person or more. Drop the item you want to dupe our let a person hold on to it for you. Hit F1 than type in exit. Come back to the same game, get the item from the ground where you left it. Now it has been duped in your inventory. Hit Esc, click exit to save and character's item is then saved in your inventory.

Killing Carnivorous Plants Easy:
Use your wizard or conjuror. This is very easy just cast a burn spell on the plant and this will kill it!

Stay Down:
To kill a zombie just shoot a fire ball at him and he will burn istead of rising back up again
