This [Nova Prime] is very solidly tanky while also having an extremely good molecular prime. Use prime every once in a while to wipe the floor with enemies, and keep your stars up. just 6 or 7 enemies will completely refill your stars, with proper timing and management you can activate them at the beginning of a mission and keep it up the entire time. [Narrow Minded] is the star of this build, as lowering the range is actually beneficial to null stars staying on you, while not affecting molecular prime, since it's range is based on duration!
the arcanes are not necessary, they simply help out if you have them! just consider them recommendations from me.

The aura forma is necessary for this!! it allows you to swap this with speed [Nova] builds
