This is my all-rounder build that's optimized for high levels and dishing out hundreds of thousands in damage per second while still having that [Infiltrate] for mobility and convenience. Survivability is entirely dependent on staying away from AoE and staying invisible.

Activate 3, activate 4, go ham. I suggest replacing 2 with Empower or Roar for damage, or Larva, Entangle or Resonator for more crowd control. At the time of writing I just unlocked the Helminth system and I'm using Empower as the only one of these I have access to.

Viral Heat 450k+ for the [Artemis Bow] build to go with it.
