You can swap berserker fury for Primed Fury or Drifting contact if u dont use naramon.

actually kills everything in 1-2 hits and if they dont they will die from the bleed and viral.

Sacrificial Steel is not needed but i personally recommend it if u want to hit red crits.

If u dont play with berserker fury or primed fury you would like to use Arcane strike so you have enough Attack speed or use a warframe that buffs ur attack speed.

Primed fever strike and north wind can be swapped to their 60/60 mods if u feel like its too expensive,but dont expect the same damage.

Also i recommend playing a tanky warframe if youre using this build,[Nidus] or [Inaros] would be the best.

U can use the Vulpaphyla Panzer build i use,just click and see my builds.

If you have any recommendations i would like to read them in the comments ^^.
