NOTE: Before you share your feedback,keep in mind that this is just an experimental build intended to imitate the Stalker's attributes and abilities. I will explain everything further below. This time,this build focuses on his second incarnation aka the Shadow Stalker.

The Mods:

Aura: [Steel Charge] since [Exalted Blade] and [War] will really benefit from the damage bonus.

Exilus: [Speed Drift] for casting speed and extra mobility. You may also swap this for [Power Drift].

The overall mods:
[Adaptation] to mimic Shadow's Sentient [Adaptation].
[Rolling Guard] for survivability. Removed for Slash Dash as a better alternative.
The rest of the mods are beneficial for this imitation build.

The Arcanes:

I recommend the following: Arcane [Guardian],Arcane Grace,Arcane [Fury],Arcane Strike or Arcane Ultimatum.

The Arcane Ultimatum can be useful when using Radial [Howl].

[War] and EB will benefit from both Arcane [Fury] and Strike.

Only have Arcane Grace if you don't have a [Regen] precept installed in your sentinel.

The Abilities
Another Note: Since we are limited in terms of abilities and subsumed abilities,I had to be creative and resourceful over Excalumbra's powers to imitate Shadow Stalker

Shadow Stalker has [Rhino] Charge but we have Slash Dash to imitate it. It also provides a temporary invulnerability as a better alternative for [Rolling Guard].

Radial [Howl] can be used like Shadow Stalker's Dispel except that it doesn't actually dispel enemy abilities but still useful for disabling and stunning enemies nevertheless.

Shadow Stalker has Pull so I subsumed Pull for this build as it is useful for ragdolling enemies and bringing them closer. I recommend using this in conjunction with [War] or [Exalted Blade] along with Radial [Howl]. Lastly,enemies affected by Pull have around 62% chance to drop energy orbs.

His [War] can summon beam waves like EB does but I decided to keep EB for this build to use it in conjunction with [War] because [War] cannot generate energy waves like EB does.

Aside from those four abilities,Shadow also has energy sphere attacks that are unfortunately hard to imitate,check further below to see the imitation I made about those two energy sphere attacks.

———————————————

My thoughts on this build:
I have the same thoughts on this build,just like the one I wrote about the Stalker Imitation build but with slight differences in terms of opinion.
Unlike his first incarnation, Shadow Stalker is more like a melee tank caster.--

Tips:
❑I recommend to always try to engage enemies in close quarters by pulling them to your range and blinding them.

❑Decently good for solo or squad gameplay.

❑Remember to sometimes do slam attacks to ragdoll enemies and always try to block with [War] to reduce incoming damage.

❑Avoid engaging too much enemies in open areas,it's best to engage them in narrow or tight spaces to get the best out of [War] or EB along with Pull and Radial [Howl].

Extra Notes:
I cannot guarantee or claim that this build is effective since this is just an experimental build meant to imitate a field boss.
