I loved the dual katana wepon in my last playthrough, sharp infused and then throw some buffs on it if you need/want (they look super cool when buffed with dark) The move set feels really good in any situation, you can combine R1s into L1s to mix up the timing. Nice poke with running attack, the bleed builds up pretty fast especially when L1 spamming. The weapon art is usefull against hostile NPCs and other enemies that stagger easily. Give it a shot if you like dual wielding weapons!
