For nidus, focus on strength, range, and duration. Disregard any shields, as well as efficiency. I run all 3 Umbral mods - Adaptation - Blind Rage - Hunter Adrenaline - (flex but chose Primed Flow). As for aura and exilus, I run Corossive Projection - Primed Sure Footed. I dont usually run Primary when playing Nidus, but Ignis Wraith or Amprex just for fun.
