Hello there,

Introduction:

I'm so glad you guys don't like and don't play [Zephyr] (Prime)... she is so underrated, so unpopular, that the fact she is the strongest Warframe in the entire game make me simply happy, because I can be sure she is not going to be nerfed soon.

So yeah... the fewer people use Zephyr, the better :D

Playstyle:

• always keep her Turbulence active
• cast Airburst to group your enemies
• cast Tornado, shoot tornados you just created, watch enemies simply dies
• use Tail Wind whenever you want to move fast or simply fly
• combine her skills, fly around, pull enemies into tornados, shoot tornados, be the MVP, that never dies

Attributes & Abilities:

In this build I got "negative" Strength, because playstyle I present you here does not need Strength, all her damage comes from weapons fired into her tornados
High Range is here mainly for two reasons, first is pull radius for her Airburst, and the second reason is to keep you safe from AoE damage when Turbulence is active
You can keep Efficiency neutral. It's up to you
Try to balance with your Duration between 150-250%, it will help you maintain your Turbulence uptime, your Tail Wind speed and travel, hover in the air efficiency, as always higher Duration means longer timers, means better Efficiency

Flexible mods: replace Augur Message or Streamline with Funnel Clouds or Target Fixation (use weapons with Electricity/Gas Elementals)
Optional: [Archon Vitality] is here to doubles Heat procs for abilities that can inflict them (use with Heat Inherit weapons), you can replace this completely optional mod with Rolling Guard for Status Clean and i-frames

Loadout:

• Weapons - any weapon you like, to activate [Archon Stretch] Bonus, use a weapon with Electricity Elemental on it, combine it with Gas Elemental to get serious damage output. To activate [Archon Vitality] Bonus, use a weapon with Heat Elemental, nothing is stopping you to have both :) And as always, don't forget about your choosen Primer.
• Amp - chosen Amp parts and Arcanes.
• Operator - chosen Arcanes.
• Companion - take whoever you want, but as a bonus to your Energy maintenance, you can pick a [Dethcube] (Prime) Sentinel with [Energy Generator] mod on it. Your Sentinel must kill or assist you in it to generate additional Energy Orb.

Summary:

Please, don't make [Zephyr] popular, I want her to be that way. She's my "go to" Warframe, when I want to just chill and kill. Every weapon in her hand is a Meat Grinder. I'm quite surprised that DE allows it... but I don't mind, it suits me very well, I wouldn't want DE ever to set eyes on [Zephyr]... just to spoil it.

Enjoy!
