This Rousing Air farming guide will show you the places where I farm Rousing Air in Dragonflight.
Awakened Air comes from combining 10 Rousing Air, so if you need Awakened Air, you have to farm Rousing Air.
Farming Unbound Windscourges, Unleashed Storms, and Windfiends in Ohn'ahran Plains is the best source of Rousing Air. The respawn rate is really fast, you can never run out of mobs to kill, and they are all really close to each other, so you can pull a lot of them together.
