Hello and welcome to my guide. The [Zylok] makes a good candidate for Secondary Fortifier due to its ability to use [Eximus Advantage]. The use case is simple: See an Eximus, shoot it in the face, steal lots of Overguard. This build does not feature a Riven Mod, but you can replace [Target Cracker] with one if you have a suitable replacement.

For the [Zylok] Incarnon, I chose the following upgrades:
Evolution I: Incarnon Form
Evolution II: Mauler's Magazine
(If you can aim well enough to make use of the benefit from Precision's Payoff, it is also a suitable choice for this build.)
Evolution III: Rapid Reinforcement
(Again, if you are able to make use of Precision's Payoff, I recommend choosing Extended Volley instead of Rapid Reinforcement. Reload Speed helps with ease of use for Mauler's Magazine.)
Evolution IV: Commodore's Fortune
