Hello there
My name is ian and I wanna present my [Nidus Prime] build
It has a lot of advantages and disadvantages ofc. ^^
But I thought if you read this you may are interested why I choose these mods.
Alright: I wanna have a [Nidus] which good survivability and chose at first 2 of the umbral mods which are stacking each other. For aura mod slots i prefer [Growing Power] for strength up if you deal status damage. So far so good
Then another advantage is that you don't have any shields (for energy I use [Hunter Adrenaline] and a primed version of [Flow].)
For steel path I use [Adaptation] just in case and it works pretty well too :).
To farm stacks easier I use [Overextended] which is pretty nice because you have range to pull lots of enemies in a large area and deal in the beginning low damage for stacking the stacks faster.
And in the end the arcanes: grace and ultimatum
Grace:
For better life reg
Ultimatum:
For lesser damage taking and increasing the chance that you might farming 15 stacks before you die ^^

Well have fun
