Today while I was playing KIU I went to fusion and found a flintlock staff of a value:225 I thought it would be rubshish I tried it out on multiplayer and it killed players in 2 shots depending on how far I was with the player or 1 shot with super charge im not sure and like 6 shots to kill dark pit i thinks this a glicth or something?
Check out the modifiers, they possibly have +4 or something in continous-fire, standing shot. Plus the flintlock staff is a nice weapon to shoot from afar... it excels in that.
I'm no staff user but I recognize and honour people that know how to use them.
