Hello there,
I can hear you groaning already so let’s get this out of the way: You do not need to use melee at all for the Profit Taker fight. In fact, almost the only circumstance where I recommend trying to use melee is if you are solo and need the additional elements.
However, if you are going to bring melee, then unfortunately [Maiming Strike] is still the way to go. The build above is just an example and should only be used with [Chroma] since it doesn’t use [Primed Pressure Point]. When used on other Warframes, replace [North Wind] with [Primed Pressure Point]. Spin2win!
Enjoy, THeMooN85
