exiledalchemist: If you want a more vanilla game with quality of life features like enemy health bars, highlight items, and stash then try Diablo Torch. You can find it in the download section on freshmeat-blog. It works for both single player, and lan/multiplayer. For me the Win 8.1 & 10 version worked, but you may need to use to the other version base on what Win OS you are using.
Installation is simple just extract, and drop the files into the main Diablo directory. It works for both classic, and patched version. It also doesn't need to be installed in the dx folder. Just make sure to create a shortcut to the inject.bat file on the desktop after you installed it. Then run the game, and create/load a character, or start a lan/multiplayer game. Once you are in town press Ctrl+Alt+Tab so you can tab out of the game, and then run the inject.bat shortcut. Note normal Alt+Tab doesn't work thus the reason to use the other method. After that tab back into the game and you should see the new features. If you don't see the new on screen features quit the game, and install one of the other version of the mod provided in the compressed file.
I tried this to install this but when I try to run the BAT file it says it "Failed to create thread in Diablo process!".
Was pretty excited to try this for the QOL improvements.
