I spent more time than i should have done this. Worked for me on Artix Dinit, probably should work on other distros.

1. Apply the Seamless Co-op mod, configure the ds2sc_settings.ini.
2. Apply online-fix.
3. Add DarkSoulsII.exe to Steam as a Non-Steam Game.
4. Add WINEDLLOVERRIDES="OnlineFix64,SteamOverlay64,winmm,dnet,steam_api64=n,b" bash -c 'for i; do a+=("${i//DarkSoulsII.exe/ds2sc_launcher.exe}"); done; exec "${a[@]}"' _ %command% to Launch Options and use any Proton past Proton 7.
5. The game should run, have fun.
