This is essentially @Patacakes's #Atterax Max Damage (NoRiv - No Meme strike) modified to use Sacrificial Pressure and Sacrificial Steel. Still a WIP, testing If I like this despite the reduced range due to replacing Primed Reach or if I'll [Sacrifice] raw damage to increase range. I also replaced Primed Fury with Berserker Fury as suggested in the original build's description for that extra 15% attack speed.

This build can be used with the original build's polarizations, but you can also polarize Buzz Kill's slot to save an additional capacity point. You could use 2 Umbra Formas to minimize forma use to 3, but that'd be pure ostentation in my opinion. Yo can also fit the extra capacity requirements by adding an extra forma if you don't want to spend umbra formas, which to be honest would be the smart choice if you don't mind the added restriction in case you want to use other builds too.

I'll reproduce the original build's description below for reference.

Atterax - Max Damage (no riv / No Meme strike)

Requirements.

Naramon Focus - Power Spike

Basically without using a Riven or Maiming Strike, this is probably the most effective build you'll find for the Atterax.

It relies on Blood Rush to top it's critical chance with Combo multiplier. Naramon's Power Spike is used to keep the crit chance up (by keeping the combo multiplier up)

Rivens can be added depending on the stats on the Riv, just remove the corresponding mod the riv is able to match.

And

You can switch out other mods if prefered / required

Fury > Berserker
Pressure Point > Sacrificial Pressure Etc.
