Sorcery: Air Spells III
And here are the last 3 air spells, that have nothing to do with lightning. Devitalize Air is a suffocating area spell. Wall of Wind is a good defense against projectiles. Air Vortex can whisk away multiple creatures.
Sometimes I get an urge to make some GURPS content, be it something original, or something converted from another system/media. Maybe if I post it here, it will be useful not only to me. Keep in mind that I'm not a native English speaker and please forgive any mistakes.
