Arcwind

Creates a 20 foot radius, 40 foot high cylinder of high winds which batter and cut every creature within the spells area of effect. Creatures affected must make a dexterity saving throw.  Creatures that fail the saving throw take 6d8 bludgeoning damage and 4d4 slashing damage. Creatures that succeed in their saving throw take half of the bludgeoning damage and none of the slashing damage. Furthermore, if the castor has advantage on attack roles against the target for whatever reason, the target must do their dexterity check with disadvantage. The spell crits if they fail, and does full damage if they succeed.

If crit: Use twice as many dice.

At higher levels: Starting at level 6, add 1d8 bludgeoning damage and 1d4 slashing damage for each level above 5.
