Whirlpool snap

In an instant You twirl and pull in moisture in the air centering on a point up to 60ft away. Everybody within a 15ft radius cube must make a strength saving throw. On a failed save each target is pulled in and slammed into each other at the point, dealing 4d6 bludgeoning damage. On a successful save they take half the damage and are only pulled 5ft towards the center point.

If only 1 creature fails the save they are thrown 1d20ft, rounded to the nearest 5, opposite of the center point

at higher levels this spell does 1d8 extra damage, and radius increased 5ft more, for every 2 spell slots higher than 4
