the best wep in DPS of the game is the wave of the DF, even more powerfull than DM and lk, coz when ur still shoooting, u already kill the moobs with the wave of the df, so definily if u training u dont need to spheres the df coz already work without any % just the hit.
but @Fyrewolf5 have a really good point zanba really works using berserk
i guess @Arturoux want the zanba doing great damage just doing hard attack
