Twister

Strong winds hurl around in 50-foot-tall, 15-foot radius Cylinder centred on a point within range.
When the cylinder appears, creatures inside it make a Constitution Saving Throw (with Disadvantage, if they are flying). On a failed save, the creature takes 3d8 Thunder damage, is pushed 10 feet away from the center of the cylinder and is Prone. On a successful save, the creature takes half as much damage only. A creature also makes this save when entering the cylinder or ending its turn in there (only one save per turn). Objects that aren’t carried or worn get pushed 20 feet away from the center of the cylinder.
