You can take whatever weapons you want. Make sure to have a solid arch gun build. Best ones are [Kuva Grattler], [Kuva Ayanga] IMO. [Shepherd] is to keep the [Smeeta Kavat] alive, you can run whatever you want in the Aura. Just using the bond and [Bite] mods for the extra free cast. You don't need much strength with this build because you are mostly casting 1 to stay in the air. Cast 3 to basically become invulnerable between the ability and the Boreal mods. Cast 4 to aid with damage and 2 to drag the enemies into a pile or into the tornado. Come down when you need energy. Great setup for conjunction survival and high ceilings (just watch out its really easy to teleport through the ceiling in some game modes). Flex mod is [Funnel Clouds], you can put [Augur Reach] or some other mod depending on what you need. I like to quick case funnel clouds to help with damage output or if doing defense put it stationary.
