This build is mainly for using [Ash]´s blade storm, not so much for using [Venka].

Attack speed, combo count chance and combo duration are the only stats that [Ash]´s Blade Storm will benefit from. Berserker and many other mods do not work with Blade Storm. (Check wiki)
The top 4 mods are for Blade Storm, the bottom 4 are for [Venka].
You can replace [Vicious Frost] with a riven, [Body Count], [Primed Fury], [Organ Shatter], [Condition Overload], [Weeping Wounds], [Gladiator Might], Smite mods... many options.

If you are using Naramon then you dont need [Gladiator Rush] and should consider using something else, but honestly I think Zenurik is better for [Ash]. You always have energy to stay invisible and stay alive. The augment mod "[Rising Storm]" will pretty much guarantee you max combo always anyway, so I dont see the need for Naramon if you are using this augment.

I recommend using [Rising Storm], Zenurik, Arcane Blade Charger, [Steel Charge], [Coaction Drift], [Savage Silence] (helminth [Banshee]´s silence onto [Ash]´s first ability and use the augment for 300% dmg on Blade Storm)
