The idea of this build is to be able to take out specials and elites while in the middle of a horde without any risk. The toughness DR after Infiltrate helps in case you get tunnel visioned. This build has been tested on Auric Maelstrom and it works. It's not the Strongest but it's fun.
The Power Sword is your trash clearing tool and it can help dispose of flak and carapace armour in a pinch, with the powered up push attacks.
Your Helbore is still your best tool, you don't need to charge at all to kill quite a few specials, as long as you hit the headshot. And it does solid damage against ogryn enemies (one shot reapers)
Ammo is the dumpstat because you go through so little thanks to free ammo on crit and Aura passive.
