Wind Blade

You unleash a concentrated burst of wind at a creature or object you can see within range. If the target is a creature it must succeed on a Dexterity saving throw or take 1d4 slashing damage, if the target is an object made of wood or stone and is 5ft or smaller in diameter it is cut completely through.

This spell's damage increases by 1d4 when you reach 5th level (2d4), 11th level (3d4), and 17th level (4d4).
