Welcome! Thanks for checking out my Nikana/Melee Build~ This is the most common hybrid melee build I use!

Build information
-This build works for any slash & hybrid type weapon due to the Viral & Slash synergy
-This build takes advantage of Arcane Strike & the Naramon Skill Tree (Power Spike)
-For additional crit, use [Helios] & [Deconstructor] while equipping the Gladiator set onto the [Deconstructor] (That set works just like [Blood Rush], and will effect your melee despite being equipped to [Deconstructor])

This build scales well into late game, easily into SP missions. Just make sure to select the appropriate Primed Smite mod if you need to do higher level content otherwise you can use Gladiator Might/Ignore it.

Alterations
-If you do not wish to change Prime Smite out each run, use Gladiator Might or a Riven (+CC, +CD, +Reach/AS, -Imp/Punc/Enemy Type)
-If you do not run Arcane Strike: You will need to either have an Attack Speed buff or you can swap Primed Smite for Berserker
-If you do not run Naramon: You will need to either have Combo Duration mod, such as Drifting Contact, or some external source, again replacing Primed Smite
-If you wish to have an independent melee build: You will need to take off both [Primed Reach] & Primed Smite to input Berserker & Combo Duration mod. I personally don't recommend this if you are relying on your Melee.
