What about mixing these two sets in s12 if all these buffs go live? (Fan of Knives dmg buff + Natalya’s Vengeance set buff). Like full bonus from Natalya's and 2pc (+1200% dmg) from Shadow + all support legs ofc. At least it would be nice t13 speedfarming build if nothing else?
Natalya's (6) set bonus damage needs the proc from Rain of Vengeance -- and that requires 1H Xbow equipped (and can't dual wield it with melee), and you need a melee weapon equipped for Shadows Mantle (2) piece bonus.
