Magnetize is already a powerful single target ability but it can be tweaked to be a great nuke. Armor stripping from her kit allows even the less damaging nuke to scale all the way to the level cap. We subsume Breach Surge to abuse a specific interaction where the bubble double dips off of any damage you shoot into it.

Breach Surge is specifically tailored into this build but with above par stats in all directions almost any ability can be chosen. Pull is replaced because it's weak in comparison to the combo of the other 3 abilities.

Strength is high enough to hit the armor strip cap on [Fracturing Crush]. It hits this cap at 160% Strength and isn't able to strip any more than 80% armor. [Transient Fortitude] can be replaced with [Blind Rage] if you're running with an energy support frame.

Range is boosted up but isn't maxed because the build suffers trying to make up for the lost 60% Strength from [Overextended]. If you really need the range you'll need to use additional slots on Strength.

[Primed Flow], [Streamline], and [Augur Reach] are flex slots. I wouldn't suggest dropping [Natural Talent] as Crush has a ridiculously long cast time.

[Corrosive Projection] combined with [Fracturing Crush] and Polarize allows the build to scale even farther towards the level cap through the compete armor stripping. Any other Aura can be chosen against enemies outside of long endurance.

Arcane Aegis allows you to spam Polarize or other abilities in conjunction with an Augur mod to stall until it procs. It can be replaced with any other arcane of your choice to suit your playstyle.
