DSR Soul Dupe Glitch 2.01 Post Patch (Parry & Riposte)
Instead of having to do it all while in a roll just parry something and do it while riposting with your barehand, this gives you far more time to set up the glitch.
Credit to Kolobok for finding a way around the patch, and giaquinto for posting this on the subreddit. But this will never get more than 100 views so who really cares.
