Hi! I'm Neklas.Octan (my ign on PC)

This is 1 of my favorite weapon in Warframe.

I make it with viral/slash for most effective now. Also, it is a slash-based weapon, great synergy with skill Despoil of Nekros.

You can use it as Meat Slicer to boost your [Nekros]'s [Despoil] skill. Remember, to tear the enemy's body apart, you need to kill them with Slash damage, not Slash proc.

This is my test video for the above concept: https://www.youtube.com/watch?v=5xsnoq_973Q

Update 22 Aug 2022:

Change to Primary Merciless, because the stack will drain one by one, - 30% dmg doesn't matter.
I still keep Vigilante mod set because of the 10% chance to increase crit tier (If you deal yellow crit -> 10% chance to have orange crit)

Update 12 May 2023:

Change to Primary Deadhead, for faster dmg buff stacking and also for Incarnon Genesis.
Equip Vigilante Mod set on Sentinel weapon for crit tier buff.

Update 22 Sep 2023:

We will use Rank 9 Galvanized Scope(https://warframe.fandom.com/wiki/Galvanized_Scope)
The final crit chance is: Base 12% + Max stack bonus 291.1% = 46.932%
So we can still get benefit from Incarnon Evolution IV:
Perk 2: Prelude of Might
With Critical Chance Below 50%: Increase Critical Damage Multiplier by +3.4x (Braton) / +3.3x (MK1) / +3x (Prime) / +3 (Vandal).
And, have a decent value of crit chance.

Evolution II:
Perk 2: Munitions Grit
Multishot consumes ammo directly from Capacity and increases Damage by +60% (Braton) / +48% (MK1) / +54% (Prime) / +58% (Vandal). +20% Multishot.

Or, you can choose Perk 1: Daring Reverie from Evolution II, when you have Gloom or playing as AOE [Equinox] or [Oberon].
Channeled Abilities

Evolution III
I choose Perk 3: Gunsmoke Pick Up for Ammo [Regen]

Evolution IV
Perk 2: Prelude of Might
With Critical Chance Below 50%: Increase Critical Damage Multiplier by +3.4x (Braton) / +3.3x (MK1) / +3x (Prime) / +3 (Vandal).
The Vigilante mod set bonus will upgrade crit tier of critical hits, so u can still deal orange crit and have the above CD bonus.

Update 13rd Nov, 2023:
Use rank 1 Point Strike to get 45% crit chance when Incarnon mode is active, to take advantage of Perk 2: Prelude of Might
