This Build works using a small interaction between Galvanized Scope and Primary Deadhead. Using the secondary fire on the Kuva Bramma allows you to do airburst crits/headshots. Using this, you'll find that you will pre much only see orange/red crits even on high level enemies in the steel path. The warframe I use with this is a full power build [Banshee]. Her second ability gives enemies weak points, which can be hit by the explosion. Having the helmith, you can either use empower for casting your number 2 or [Rhino] roar for more damage for allies.
