Profits? Taken.
This is an effective anti-corpus build for the [Mausolon], made with the Profit Taker in mind.
If you just want to use it on the Orb Mother itself, drop the toxin damage and save some forma, the toxin is just there to help bypass shields so the minions die faster.
The main point of the build is heavy radiation damage, as Profit Taker is not a fan of radiation. Combine this with Roar or Eclipse and watch the Orb Mother melt in moments.
[Mausolon] is a great Archgun for warframe combat with the Profit Taker due to good damage per bullet and a large capacity meaning the cooldown before being able to summon it again is quite short, and it's primary fire damage combos very well into radiation.
