In the game Dungeons of Dredmor, many people have been seeking out how to make Diggle Nog. Well, the process is simple if you chose to be an Alchemist to start the game, but can be done with any character you choose. Here are the directions:
Get or find a Porta-Still
If you start as an alchemist, you have a Porta-Still already when you start, otherwise you need to find one
Get a Diggle Egg from a Diggle Monster
Buy Grog from a vending machine
Get Aqua Vitae
Again, if you started as an alchemist, you already have some. Otherwise, you need to get some.
