This is just a copy pasta from my post in another thread but I did this to bump this guide and help out with it. I know this GI works cause my impact count went up when I tested it in arcade.
The best way to do Momentary Plesure is with a friend of course and do Y hold Y with Xiba so in other words BB
in game terms.
The first hit is so your friend knows an impact is coming then have said friend do a horizontal since that is what it impacts. Whats good about Xiba's is his auto GI doesnt have an automatic attack come out like Patroklos. So you can set the rounds to 5 and do this til the time runs out.
