Downdraft

Dropping the small carving in your hand to the ground, you crush it with your foot as you recite the last few words of the spell. in the distance you see a column of air turn a hazy gray. The air column then blasts towards the ground, and you hear a distant whoosh.   Downdraft sends a column of turbulent air rushing towards the earth. Airborne creatures caught in the area of a downdraft must succeed on a Reflex save or immediately plummet up to 100 feet straight downward, taking falling damage (1d6 points of damage per 10 feet fallen) if the downdraft makes them hit the ground or collide with an object. Those who succeed on the Reflex save plummet only 50 feet.   Creatures already on the ground must succeed on a Reflex save or be knocked prone by the spell.   Material Component: A balsa-wood bird carving, which is crushed underfoot.
 

You summon a violent column of rushing air that blasts downward in a 20-foot-radius, 100-foot-high cylinder centered on a point within range.   Flying creatures in the area must make a Dexterity saving throw. On a failed save, a creature is hurled up to 100 feet straight down, taking falling damage as normal if it strikes the ground or another solid surface. On a successful save, the creature is forced 50 feet downward instead.   Creatures on the ground within the area must also make a Dexterity saving throw or be knocked prone.   Objects in flight, such as unsecured balloons, gliders, or falling debris, are similarly affected at the DM’s discretion.   At Higher Levels. When you cast this spell using a higher level spell slot, increase the radius of the Cylinder by 5 feet for each slot level above its base level.
