Tales of Tolgard
Air Elementals are semi-humanoid elemental monsters which are forces of nature. They appear as amorphous, shifting clouds with fast moving currents of air surrounding them. Darker bits within the whirlwind suggest two eyes and a mouth.
Air Elementals speak Auran.
Air Elementals can most often be found on the Plane of Air, but occasionally visit the Material Plane, usually at the behest of a summoning spell.
