NOTE:
Has been nerfed to the ground, the original fun and enjoyment isn't reflecting the current build and gameplay.
But will leave here, if DE ever decides, like in 10 years, where Warframe is dead already, to revert these nonsense nerfings.

Wanna troll with a [Loki]? Use "Banish"!
Wanna spread fear and confusion? Use "Marked for Death"!

Examples:
Steel Path Comba lives
Steel Path Comba ded
Ded Lv170 Exo Gokstad Officers
Steel Path Scorpion: REEEE - 45mil dmg

Today I am bringing you the hilarous 2 ~ 255 mil damage [Loki]. You can easily outdamage every other player with this build (as long as they don't do the same shizzl)!

Simply put: Huge ass range with lots of speed and mobility for running, bullet jumping and dodging/rolling away!

As for the benefits of finishing enemies (later more for the requirements), you want to get an Arcane Tricker for yourself. Each enemy killed with MfD will trigger the arcane quite successfully (9 of 10 times), even if the enemies dying from it ain't marked!

As for the process:

• You want this [Bronco]:
  [*] Utility - No Forma - Finisher Opener! (Pacheon)
  No, you won't use the Primed one and the necessary mod in that build won't work for the dual broncos!
  Also, this [Bronco] offers the fastest reload speed. We ain't aiming for damage.

• And also this Hammer:
  [*] Punch Punch have a Lunch! - Finisher Build (Pacheon)
  Yes, a hammer. Daggers used to be the "silent assassin killer weapon", but DE has some kind of weird taste of making jokes ... jokes which are still holding up today.

Approach:

• Select your enemy you wanna sent to oblivion,
• shoot it with your Bronco
• and finish it off with your Kuva Shildeg (don't simply quick-melee it, use your activation key).
• The more enemies nearby, the more fun you will have!

Done.

That is it.
Steel Path like: We stronk!
[Loki] goes like: Brrrrrrrrrr!

Have fun wrecking the entire crap out of every single enemy type in the entire system and seeing enemies flying around because of the impact, Tenno! :D

Best regards,
Pacheon
