For Usage with an Warframe using Arcane Tempo to massively up Dps through that Fire Rate.
If you don't use a Riven next best is Sweeping Serration > Faction-Mod.
Well if you don't use the Warframe Arcane then of course you put [Shotgun Barrage] in the Rivenslot.
The Idea is to hold the Fire Button pressed (to hold on to max dmg) and tap all Enemies short with a Headshot so they die of high-dmg/high-amount Slash-Procs. If you don't fire at an Enemies just target slightly up so you don't use up Ammo (thatnk [Efficient Beams] for no Ammousage without hitting a target^^)
