This build is intended for high enemy count mission types (survival, defense, etc) where virulence can really shine.

If you want to use this builder lower enemy count missions swap [Blind Rage] for [Primed Continuity].

On [Nidus] virulence refunds energy based on its a percentage of its cost so increasing its cost will improve your overall sustain.

If you find you are building mutation stacks too slowly swap [Teeming Virulence] for [Insatiable].

[Teeming Virulence] will increase your primary crit chance by 336% in this build.
