Backdraft

For the briefest moment you magically create a vacuum sucking all the oxygen from the intended direction of the spell and concentrating it into a ball around the material component of the spell, you then ignite it and unleash it in a 30-foot cone. There is an intense pressure that pulls or pushes creatures and objects followed by a torrent of flame. Each creature in that cone must make a Dexterity saving throw. A creature takes 6d6 fire damage on a failed save, or half as much damage on a successful one. And every creature that fails the save is either pulled 15 feet toward you or pushed 15 feet away from you, depending on the choice you made for the spell.

In addition, unsecured objects that are completely within the cone are likewise pulled or pushed 15 feet and set ablaze.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 and the distance pulled or pushed increases by 5 feet for each slot level above 3rd.
