Autumn Gale

The Autumn Gale is a magic book that drops from the Autumn Slime during the Autumn Moon event. It has a Tornado on a gray-brown cover. When used, it fires a tornado that sweeps the screen, sucking up any mobs it comes across. When it reaches the end of it's run, it bursts apart, dealing high damage and knockback. It is the most mana expensive magic book pre-Hardmode.
