Hello there,

Introduction:

[Ash] got buffed! This is a perfect moment to enjoy playing as him. Without further ado, I'll get to the point... to play ninja.

Playstyle:

• Start the mission, go invisible (Smoke Screen). Start killing spree. Collect Energy Orbs, build Combo.
• Cast Silence (Banshee subsumed ability), re-cast when it expires. Remember about it, this ability can prevent Eximuses and Acolytes to use their abilities around you.
• If you encounter a very tough opponent (Stalker, Acolyte, Boss, Demolyst, etc.) on your way, soften it with Shuriken (strip its armor). With fully stacked Molt Augmented, you need only one cast to fully strip any armor.
• Stay invisible thanks to Arcane Trickery (or Smoke Screen if needed), and mark your enemies with Blade Storm, activate it again to carry out the execution.

Attributes & Abilities:

Strength - with fully stacked Molt Augmented (250 and more kills), you gain 144%, and to strip any armor with Shuriken (with its augment), you need exactly 143%. Well, you have it. It also affects Blade Storm damage output.
Range - you want some but not too much, you are using Silence, so you can stun your enemies around you, but you can also move away from them and approach them again to do it again. Also affects Smoke Screen stun radius, and Blade Storm marking range.
Untouched Efficiency - it's up to you, you can actually increase it, but I personally didn't feel like I needed that. There will be plenty of Energy Orbs around you.
Duration - you want it, as much as you can have. It affects three out of your four abilities.

It is up to you if you choose to replace your Shuriken , or your Teleport, I picked the second option, because I do use an armor strip from time to time. If you pick the first option, you can actually drop [Umbral Intensify], Molt Augmented, and [Seeking Shuriken], because you won't need any Strength at all, while you decide to use the Silence. Yes! You can actually have "negative" Strength. This build will still be murderous.

Another "flexible" mod here is... [Rolling Guard]! Yes! I said that... This mod is absolutely optional, especially if you are planning to be invisible all the time, Shield Gating should be enough to [Protect] your inattentive ass. You can use this slot for more Duration, more Efficiency, even more Range, or utility like [Equilibrium], [Preparation], [Natural Talent], or whatever the hell you want.

Furthermore, Aura and Exilus are both also "flexible", pick your poison.

Aura Slot:

• Amp - chosen Amp parts and Arcanes.
• Operator - chosen Arcanes.
• Companion : Your Devoted Servant - kavat that will serve you in many ways.

Summary:

Lately [Ash] got buffed but very few people actually knew that. I was one of them. Now I'm on the other side, and now I am sharing my knowledge with you. Spread it, have fun until DE nerf [Ash] again xD

Enjoy!
