Profit Taker on-call-crew [Synapse]: used for speedruns, covering primary elements, freeing up space for better pylon times and making you not have to switch weapons during the fight.
Crew dont use rivens or arcanes, therefore none in the build.
[Shred] requires you to have +150% primary critical chance on crew or it wont consistently crit. if you dont have that, use [Point Strike] instead. I use shred for whenever my crewmate gets stuck behind somewhere so he can in theory still hit pt, also it doesnt give you the -damage that vile acceleration does
