Introduction
This [Nova] build is focused on speeding up enemies while retaining the utility of Null Star and the damage of Antimatter Drop.

[Vigilante Pursuit] is my Exilus Mod of choice due to its utility and the bonus damage from its set effect. Feel free to replace this mod with your preferred Exilus Mod.

If you don't need [Primed Flow], feel free to replace it with another mod like [Adaptation].

Defense: With 306% Duration, you are able to cover the entire map with Molecular Prime. Cast it a few seconds before the round starts as every enemy within the radius while it is active will be primed.
This speeds up leveling missions like Helene or Hydron. When your weapon is maxed out you can simply spam Antimatter Drop to clear waves faster.
Even if you have a weak weapon, you can always keep a strong Archgun on-hand to charge up your Antimatter Drop. You will have no problem staying alive in longer runs thanks to damage reduction from Null Star and Arcane [Guardian].

Survival: [Nova] can greatly speed up enemies in farming groups and in normal play, funneling them faster towards your team. More kills per second means more loot and life support drops. Antimatter Drop can help nuke groups if you find yourself in a rough spot, and Null Star and Arcane [Guardian] will allow you to take a few hits.
