Build for pumping damage into [Nyx]'s Absorb.
Crit doesn't get Absorbed.

Since Cold and Heat are required due to one being a Primed mod and one being tied to Magazine, the best elemental combo seems to be Viral+Heat. Corrosive is the best element, but requires the second combo to become Blast with the required mods, and Blast is garbage.

Riven replaces [Hornet Strike] or Pathogen Rounds.
Riven stat priority: MS > Magazine > Dmg > Toxin > Reload = AmmoMax
Crit stats are free negatives for this strat. -Projectile Speed reduces disk travel distance, a nice little QoL improvement. -Fire Rate is also a solid neg as it increases disk duration, even if it does reduce DPS.
