The goal here was to be as durable as possible on a normally fragile frame, then focus on amplifying attack speed. Arcane Energize ensures that there's enough energy to keep Razorwing up, [Adaptation] and the Umbral set to maximize durability and add some strength, and [Primed Continuity] to keep duration positive with 175% efficiency. She should use the [Dex Pixia] build found here.

This is for a clan challenge not a build I'd actually use normally for anybody just scrolling through.
