Totem of Air

Any creature within 5 feet of the totem treats the area as difficult terrain. As a bonus action, you can cause a blast of razor like wind to strike out at a creature within 30 feet of the totem. You make a ranged spell attack. On a hit, the creature takes 1d8 slashing damage. At 10th level, this damage increases to 2d8. At 16th level, the damage increases to 3d8.
