Built for Slash to deal with Armor, because it's the main hindrance when dealing with high level Armored enemies.
A Corrosive build can achieve higher kill-speed in shorter runs, but ofc falls off hard vs Armor in longer runs.

Arcane [Fury] is highly recommended to use on [Khora].

The specific weapon doesn't matter, use any you have a good Riven for, or one with a good passive, like [Telos Boltace] with the passive +BulletJump Velocity.

Riven replaces Spoiled Strike.
Desirable Riven stats in order of importance: +CD = +Dmg > -Impact > -Puncture > +CC = +Slash

Add a Combo Duration mod(like [Body Count]) if you're not using Naramon and can't keep up Combo.
