First off just no to vorpal d fan. Only reason it is good on f fan is its mass aoe. And for t sword and I sword it is full activation from start to finish.
Vorpal d fan thrust yes it does hit range it does hit x3 times. But, it has a major loop hole. 1 it is not aoe. 2 it has a another major loop hole which is its use time and its cool down. 3 it is hard as **** to aim. 20440 would be more usefull but If your going to try the hole vorpal route for d fan try 30234 this way you have another means of attack, You can get your musou back when you need it so say if you don't got the support for vorpal now you can rely on musou. So most people would say no to this build but, I did try try vorpal d fan and this method was much more effective.
