Whirling Daggers

You fill the air with whirling daggers in a 5-foot cube, centered on a point of your choice within range. Whenever a creature enters the area or starts its turn there, the creature takes 4d4 slashing damage.

At Higher Levels. When you cast this spell by spending Mana points equal to a 3rd-level spell or higher, the damage increases by 2d4 for each spell level above 2nd. When cast as a 5th-level spell or higher, this spell’s damage becomes lacerating.
