You brandish the weapon used in the spell’s casting and imbue it with the power of the winds, and make a melee attack with it against one creature within a 15 foot line of you. On a hit, the target suffers the weapon attack’s normal effects, and the squares in the line are considered difficult terrain until the start of your next turn.
At Higher Levels. At 5th level, the melee attack deals an extra 1d8 bludgeoning damage to the target on a hit. The damage rolls increase by 1d8 at 11th level (2d8 and 3d8) and again at 17th level (3d8 and 4d8).
