Welcome to 2026! The age old question remains; how are you running Battle.net on Steam OS in Steam Deck?
I had an itch to try out the new class in D2. So I fired up the old Battle.net install that I previously had running through Lutris when D4’s expansion came out. It’s been a while, and something obviously changed with the Battle net launcher that it was broken in Lutris. I had to uninstall and reinstall numerous times through Lutris until it finally took properly.
Curious if lately others are simply installing it and running via Proton as a non-steam game that I can sidestep the Lutris process?
I saw there was NonSteamLaunchers via Decky Loader, but I couldn’t figure out how to get it installed and it wasn’t showing up in the plugin store when I searched for it. It was late so I didn’t have enough time to dig further there. The Bible quotes also seemed weird in the git, but whatever, if it works I’d be willing to try.


Lutris works best in my experience for running it. I have battle.net running through proton 10 in it. I think I ended up installing battlenet.exe through steam, then swapping the prefix to the steam-created one in Lutris because Lutris was having issues installing the launcher for me. Wow and D2R work fine, but I haven’t tried D4.
Steam was a pain in the butt by itself for me.
