The Staff of Air is an enchanted Quarterstaff +2 which can destroy air elementals when they are hit by this weapon. The weapon deals 1d6 +2 points of crushing damage, has a -2 THAC0 bonus, weighs 3 lbs. and has a speed factor of 2. This staff can also be used to summon an 8-hit die air elemental for 1 hour. Both abilities require charges from this weapon. This item appears in Baldur's Gate II: Shadows of Amn and Baldur's Gate II: Enhanced Edition. It is dropped by the Master of Thralls in the Planar Prison.
This staff seems to draw from eleven artistic traditions, though tied less to the forest than is usually customary. It was apparently designed to control air elementals, being able to summon one as a servant to the wielder, and potentially destroying creatures of the same type in a single blow. When necessary, it can also spawn a cloud of gas causing anyone within the area of effect to fall into a deep slumber. Some effects are limited by charges.''
