Warframe: Spectrosiphon Zephyr

A very fun build for defense type missions.

Of the Inaros, Chroma, Octavia, Harrow and Zephyr Prime frames I currently have - the Zephyr is my favorite, especially with Gara's spectorage replacing air burst (using the Helminth) and with the spectrosiphon mod installed. With these stats (150% DUR / 130% EFF / 175% RNG / 100% STR) this is how the powers work in tandem.

Tail Wind - lets you fly or hover to make the most of Zephyr's +150% crit chance while in the air.

Spectorage - creates a carousel of mirrors that attracts baddies into its center (there's a little more that it does but it's not important in this build). The spectrosiphon mod increases the chance (up to +50%) that enemies that die in the carousel to drop energy.

Turbulence - creates an air shield that makes you invulnerable to most ranged attacks (except nearby splash damage) for a time.

Tornado - drags nearby enemies into a tornado (or tornadoes), lifting them and basically making them helpless while dealing low damage. This damage can be increased by shooting the tornadoes (or you can attack them directly). A tap on the button lets the tornadoes run amok. Holding the button down keeps them in place.

So the sequence is cast spectorage where you expect enemies to pass - they'll want to come close to the mirrors. Cast a non-moving tornado in the center of spectorage which will pull them in. Kill them while they are helpless. Collect lots of energy. Repeat.

This defeats most infested units. Against gun wielders, either put this trap around a corner or you go around a corner after putting it to lure them in. Don't forget Turbulence makes you invulnerable to their fire. Very handy. Still doesn't replace my Loki for stealth, nor Slowva Nova for interception, but it's definitely one I'm keeping around.
