This spell is a part of the Airess spell chain and can be found in the Airess rune stone.
Not every aeromancer who calls on the West Wind is asking for shelter. Zephyr's gift, after all, was never only comfort - spring is also the season of sudden squalls, of gentle mornings turning sharp without warning, and an aeromancer who has learned to ask for protection eventually learns they can ask for something with more bite instead. Air Burst is usually the first such lesson, simple enough that even a young aeromancer barely past their first cast of Airess can manage it, though simple does not mean gentle.
To cast it, the aeromancer gathers a fistful of West Wind's own current and works it between their hands until it thickens - folding, compressing, refusing to let it dissipate the way loose air always wants to. What results is a taut, invisible bubble of concentrated wind, no bigger than a melon, humming faintly with the pressure it's holding in. Thrown at a target, it doesn't so much strike as arrive - and then, all at once, it isn't a bubble anymore. It pops with a violence entirely disproportionate to its size, the compressed air unleashing outward against whatever it touched, dealing 2d12 points of damage. The aeromancer, more often than not, grins at the sound of it - Zephyr's currents were never meant to hold that much pressure for long, and there's a particular satisfaction in being the one who taught them how.
