Anyone Can Float

You pull three large balloons from your pocket and make a melee spell attack against a creature you can see within range. On a hit, you clip the balloons to the creature as they begin to magically inflate.
The creature is lifted 10 feet into the air. On the start of each its turns, the creature rises 10 feet to a maximum of 10 feet x the spell slot level used to cast the spell. A creature may either use an action to attack a balloon, or, at the end of each of its turns, make a Dexterity saving throw to attempt to escape. If it frees itself, it immediately drops to the space it previously occupied space. At the end of the fall, the creature takes 1d6 bludgeoning damage for every 10 feet it fell, to a maximum of 20d6. The creature lands prone, unless it avoids taking damage from the fall.
If that space is now occupied, the occupying creature takes half the original falling damage and is pushed to the nearest unoccupied space. When the spell ends, the balloons slowly drift back down to the closest unoccupied space before disappearing. If the creature is still attached, they are unharmed.
