CONCLUSION OF THIS BUILD
For this build to work properly, I suggest using a Warframe that provides speed for melee weapons, such as Volt / Gauss / [Valkyr], or having another source of speed, since you need speed to apply the combo and faster state.
I use Melee Afflictions since with the [Spinnerex] it applies the activation very well , the truth is that this weapon works much better for Corpus enemies because of the Toxin damage.
.
BUILD CORPUS -> For this fraction the same build would be used but only changing Smite Orokin Prime for Smite Corpus Prime
BUILD GRINEER -> For this fraction the same build would be used but only changing Smite Orokin Prime for Smite Grineer Prime
