This build is all about flying around to stay alive and nuking everything from orbit! I toggled the ability tap/hold for this frame to make her easier to use.

Tap Tailwind (1) to suspend yourself midair to activate DR from [Aerodynamic], [Aviator], [Boreal's Anguish], [Boreal's Hatred], and [Boreal's Contempt] (equipped to a polearm) for a total of 83.9% DR while airborne, plus additional DR from stacks of [Adaptation]. Being airborne with your 1 also triggers your passive of +150% crit chance with weapons and gives you a better vantage point to rain [Hellfire] on groups. Subsumed Eclipse over Airburst (2) for an extra +150% weapon damage in the light, or more DR in the dark. Usually mid air you'll be in the light. Can also use Dispensary for 2 free energy orbs plus healing and ammo - and yes, it does spawn and stay in the air with you! Use Turbulence (3) to make yourself unable to be hit by projectiles! Don't need to babysit refreshing this as closely since the airborne DR will keep you from getting oneshot if it drops. Hold Tornado (4) to create wandering tornadoes that go towards where you're aiming and group up enemies along the way. If camping a hallway or small spot, tap 4 to create stationary tornadoes that stay where you place them.

Works really well with AoE weapons with high crit and damage. I like to use the [Nataruk] as it has punch through for the groups in tornadoes and infinite ammo so I don't have to be concerned with picking up ammo. This combo has enough damage output to kill Steel Path corrupted enemies well over 30 minutes into a survival and beyond (lvl 200+) through their armor. If armor is a concern, bring a secondary that is good at applying max stacks of corrosive to groups to shave off a ton of enemy DR and nuke them back to the stone age!

Uses Arcane Energize to keep up with the drain from staying airborne and pay for recasting 2,3,4 every 38/31/31 seconds respectively. Uses Arcane Acceleration for additional primary fire rate on crits (remember that innate 150% crit chance while airborne?)

[Zephyr] go brrrrrrr, Tenno

(PS. This build only needs 2 forma, I just like having Aura Forma installed on all my frames so I added that, but the polarity already matches the aura!)
