Reddit mentions of Diablo II: Diablerie (Dungeons and Dragons)

Might check out something like this - https://www.amazon.com/Diablo-II-Diablerie-Dungeons-Dragons/dp/0786917601

They made a few products in that line...

Diablo II: Diablerie is a d20 D&D supplement that has a great system for magic items. I haven't played it extensively but it does look like it would be a good groundwork for what you're looking for https://www.amazon.com/Diablo-II-Diablerie-Dungeons-Dragons/dp/0786917601

Have you considered adapting the 3rd edition Diablo 2 book for use with d20 Future? It has lots of charts for random magic item properties.

Diablo II actually has a D&D version. Note: "the D2 books were written BEFORE 3.0 was released, using beta copies of the 3.0 books and are therefore full of mistakes." https://www.amazon.com/Diablo-II-Diablerie-Dungeons-Dragons/dp/0786917601

There's also the secret cow level: https://www.wizards.com/dnd/article.asp?x=d2/d220010302x1

Really, though you're better off using something like 5th edition or Pathfinder, finding monsters that match up and designing the adventure using those systems as they'd be way more balanced (and better written).
Here's a link to some folks discussing ideas on how to set up an adventure: http://www.enworld.org/forum/showthread.php?66948-Diablo-d-amp-d-3ed-any-good There are some neat downloads in the thread but it just backs up my impression that you'd be better off custom making your adventure and doing it as a one night one-off.

They made both a boxed game as well as a few official D&D Diablo II books back in the early 2000s.
