If you have an edited character, and he/she is capable of using a sickle.(If not to get one you must do chronicles and get a level 20 Thief, or level 20 Ninja, or level 20 Samurai. You can also get things from doing so many battles with a class in normal mode. The fastest way to do that is two player mode and have the other person on 0% health. I do not know how many battles you must fight with each class to get them though,) If you have you're controller set to default, or atleast have it how it normally is. You can press L2 and your person will do a fairly fast executed attack that breaks people's guard. If you can keep your distance and do this over, and over again, and maybe throwing the other person if things get to bad you can get lots of easy wins. I have tried this and it works real well. I managed to beat medium survival in soul arena with this on my first try, but it doesn't work all that great in hard mode.
