My brother and I created a mod for Diablo II which I can't play the game without anymore. Unfortunately it only works with 1.10. I've been trying to get him to update it for 1.13, but I think he's done with the game, so it's a waste of his time. I'm no programmer, so I wouldn't even know where to begin.
The mod basically just makes use of the junk in the game. It gives options to use those crappy rings and charms and keep transmuting until you get a little luckier (costly of course). It also makes finding the goods a bit more achievable. You can craft a unique of your choice if you find the right materials for it (about 3 in a full Normal-Hell finish).
I don't think anyone is going to waste their time to update a mod that has no benefits. Lucky for you making mods isn't hard in diablo 2. Do a google search for "Diablo 2 mod making turtorials". You should be able to find all the tools and information you require. .
