Place the ArticWolf folder in %appdata%\runic games\torchlight\mods\

Example, it should be something like C:\Users\Username\Appdata\runic games\torchlight\mods\ArticWolf

If your appdata file folder is hidden or if you can't find it for some reason, go to start then click on run and type %APPDATA% to access your application data directory

I hope you enjoy this mod.

Many thanks to Ergonyx for making this possible for me!
