Wind Blade

Call forth and shape a gust of wind, honing it into a cutting edge. Make a ranged spell attack on a target within 30 feet that you can see. The target takes 2d6 slashing damage on a failed Dexterity save and half as much on a successful one.

Another way to use this spell involves a blade. When making a melee weapon attack with a bladed weapon, you can consume a spell slot to use Wind Blade instead. Using Wind Blade this way uses your weapon attack DC, depending on the weapon, instead of your spell casting DC. On a hit, add your weapon damage to the total.

Upcasting Wind Blade increases the damage dealt by 1d6 per level above 3rd.
