my unkillable slow nova build
my fast nova build
This is a tanky Neutral [Nova] build.
This build is essentially exactly the same as my Unkillable Slow Nova build except for a two key differences. The enemies not being slowed down at all by your Molecular Prime, which is nice if you don't want to slow down the mission or you don't want to annoy your teammates. All of your abilities being more energy efficient too, however, these changes come at the cost of being slightly less tanky.
Honestly, this build requires much more work only to arrive at the exact same result as this build by Taurael. The only reason this exists is so that it can fit with my Unkillable Slow Nova build. If you don't care about having my Slow [Nova] build and would just like to have a Neutral [Nova] build, just use his build. It is much easier to accomplish. Go read his guide on how this build works if you'd like more information.
The Exilus mod can be anything you desire. I use [Vigilante Pursuit] because I like the extra 5% chance to enhance critical hits that it adds.
