A violent gust of wind 40 feet long and 5 feet wide shunts from your palm. Each creature affected must make a Strength saving throw. On a failed save, the creature takes 4d8 thunder damage and is knocked back 15 feet. On a successful save, the creature takes half as much damage and isn’t pushed.

In addition, if a creature is pushed into a wall or another creature, they both take an additional 2d8 bludgeoning damage.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the width of the spell increase by 10 feet and the thunder damage increases by 2d8 for every two spell slot levels above 3rd.
