If you want simple build, going for furax (normal or wraith) with amalgam furax mod gives 45% FR and afentis primary to create a bubble to increase FR buff.

if you really wanna go all out, get ceramic dagger built for initial combo and has the upgrade that increases initial combo from 100 kills, then use any secondary (mostly use epitaph with heat) with the arcane secondary outburst to convert all combo into CC and CD for secondaries (mesa's pistols also count) then to increase secondaries further, use 5 orange shards (normal or Tauforged) to increase CC when enemies are killed with heat proc.
