Is there any?
I was trying to solo Apollyon SE recently, and took my DNC. Everything is fine until floor 2 cleared. And at floor 3 I was smashed by the corse NM since I forgot Mensur Epee is a piercing type damage. Then I re-looked again the list at FFXIAH; It seems all the swords for DNC out there is rapier type (i.e. piercing damage type).
Do we really have no slashing damage swords we can equip?
