This is a total all-rounder build. It'll work with all of [Zephyr]'s Augments, and allow you to Subsume a lot of other abilities onto her if you'd prefer.
With [Jet Stream] you're great for fast navigation, the average Strength, Range and Duration gives you plenty of time and easy casting on her abilities.
Drop Tornado's 'hold' cast, then shoot Tornado while grabbing everything in range with Air Burst (which also counters the lift-immunity that some units, like Ancient Healers, can bestow on other units).
Tip: If you use a pure Electric weapon, like the Fulmin, with a crit/electric build on it, no other elements... getting more than three enemies inside a Tornado means death. The Status procs so quickly back and forth that they just explode.
