Fighting Duke fishron post twins, idk which one should i choose

[i.am.umbra]

Shadowflame knife inflicts Shadowflame, but

Bananarang seems to have overall better stats, like speed, damage etc.
(Edit: Bananarang also has limited range, unlike Shadoflame knife)



And now idk which use to choose, if i have to use both??

You can just switch between the 2 if you're not sure. SK for Shadowflame, and Bananarang for your primary source of DPS.

Neither will defeat Duke if you have not optimised your Armour and accessories, what are your equips looking like?
