seen so much cringe here about nikana builds. this a pretty much an optimal build for the nikana prime.

• get all of your viral and other statuses from a priming weapon such as the kuva nukor
• last slot is for anything that you want to put in, such as: a riven (if you so desire -- disposition is very bad and i dont recommend one) or sacrificial steel (for dopamine red crits)
• swap smite mods every time you go against a different faction (they're a separate multiplier after all of your mods, applying on your initial hit and your DoT procs like slash)
• i would recommend using arcane strike for 60% additional attack speed
• if you don't have a secondary to get viral, replace the faction mod and use the empty slot for 2 rank 1 cold and toxin 60/60 mods (so viral doesn't overtake slash in proc priority)
