This is a Fast [Nova] build.

It's designed to speed up all enemies around you with your fourth ability (Molecular Prime) while also increasing the damage they take from all sources. This is mainly meant to be used in low or mid level defense missions to speed up the incoming waves.

This build is compatible with my Slow Nova and Neutral Nova builds.

This is how it works:

• Molecular Prime sends out a wave, slowly traveling outwards and coating all enemies it hits with antimatter. Depending on your ability strength, these units will be slowed down or sped up (see Fast Nova, Slow Nova). Coated foes will also take 100% more damage and explode on death.
• Ability range does not affect the wave. You can't change the wave's travel speed, so in order to increase its effective range, you need to pump up ability duration as much as possible (to keep it active and expanding for a longer time).
• You can achieve an enemy speed increase by modding less than 70% ability strength.
• I never bothered changing the polarity of one of the madurai mod slots, that's why [Augur Message] is sitting on a wrong polarization.

Aura:
I added an Aura Forma (Wiki article), since it enables me to use differently polarized auras for all three [Nova] builds. [Power Donation] is crucial to lower your ability strength. (This might not be displayed correctly in your arsenal.)
Edit: [Power Donation] as well as [Steel Charge] give you more extra capacity than other aura mods. Since this build is meant to be used at lower level missions as a support for your whole squad, I don't mind lowering strength a bit more. In addition, everyone else gets bonus strength, which will probably result in more damage than slightly stronger nova explosions...

Arcanes:
Feel free to use whichever Arcanes you prefer/own.
Since I'm using this build solely for lower level missions, increasing tankiness via Grace or [Guardian] isn't necessary. (I usually use at least one of these in most of my builds...)
Energy consumption might be an issue depending on your ability usage, so I'd recommend Energize in this scenario.

Subsume:
Feel free to experiment. Dispensary or AoE might be useful... :3

Edit: [Coaction Drift] does indeed not work with [Power Donation], thanks for the comment. Instead I recommend Cunning or [Speed Drift]...anything except [Power Drift] is viable here.

There's always some more potential to further minmax, but I like this build and its moderate amount of polarized slots, leaving room for variations and alternative configs.
