Not my build - taken from ChangelingRain. I'm just saving it to my profile for personal convenience.
TL;DR: Use Spectrorage followed by Tornado, then fire at tornados. Keep Turbulence up at all times, and when convenient, use Tailwind (hold while airborne) to boost your weapon damage. Along with Arcane Energize, this gives [Zephyr] a similar role to EV [Trinity], but with more damage, CC and better survivability. Notably good in Arbitrations, since the tornados deal weapon damage, not ability damage, meaning they can damage arbitration drones.
Once again, this is not my build. If you want an in-depth explanation of how and why this build works, or if you have any questions or kudos for the creator, check out ChangelingRain's original build here.
