If you die and cannot make it back to retrieve the items from your dead body, simply save, exit, and return to the game. Your corpse will appear in town and you may retrieve your items easily.
Secret Cow Level?
In order to find the secret cow level you are going to need a few things.
1. Wirts Leg
2. Beaten the Game
3. Tome of Town Portal (with scrolls)
4. The Horadric Cube
Once you have beaten the game go to the Rogue Encampment in Act I, then put Wirts Leg and a Tome of Town Portal (This has worked with random ammounts of scrolls in the tome) into The Horadric Cube. Once you hit transmute they should disappear, but once you close your inventory window there is a red portal that will lead you to the Secret Cow Level. This ONLY works in the Rogue Encampment in Act I.
A Cacophony of Sound
During gameplay, press enter. Then type: SOUNDCHAOSDEBUG to hear an uproar of voices and sounds. To turn it off, type it again.
Who wants some?
Have you ever wanted something so bad but couldn't get it? Like a book of stone curse? Go up to anybody who sells you stuff (not Wirt) and see what they have. If you want something they don't have save the game right in front of them. Then load the game and see what they have. I'm not sure if it works with Griswold or Pepin but I'm 100% sure it works with Adria.
Claim Your Items
After Death Normally when you die, your corpse will remain where you croaked, surrounded by whatever killed you. To avoid this, after you die Save and Exit the game. Now your corpse and possessions can be picked up in the safety of the town.
Easy Way to Up Gems
If you have a particular gem that you wish to increase (such as raising a chipped ruby to a flawed ruby) then this trick is for you.
1. Find a gem shrine, but dont click on it.
2. Then put the gem that you wish to increase in your inventory, but make sure no other gems are present in you inventory. It would even be smart to remove any items that you are wearing that contain gems.
3. Then when you have everything above finished click on the gem shrine.
4. The gem that you had in your inventory will be on the ground but it will be increased.
For example: If you had a flawed ruby in you inventory and you clicked on the gem shrine, you flawed ruby will be changed into a ruby!
Save Yourself From Certain Death
If you are about to die and have no Potions, simply press ESC, then Save and Exit the game. When you boot up again, you'll find yourself in the safety of the town. Now you can buy health, repair items and go to a more manageable location to gain levels.
