Balloon Ride

You tether a creature you can see to a magical balloon that appears in
the nearest unoccupied space above the target. If there is no space for the
balloon to appear, the spell fails, and the spell slot is expended. The target
must make a Strength saving throw. On a failure, the target becomes lifted by
the balloon, reducing its speed to zero, and at the start of each of its turns, it
rises 30 feet straight upward or as far as is possible if the rise is prevented by
a roof or other obstacle. The balloon is a Medium object (AC 10, 15 hit points)
and has vulnerability to piercing damage. If the balloon is destroyed, the spell
immediately ends, causing the attached target to fall.
At Higher Levels. When you cast this spell using a spell slot of 3rd-level or
higher, the spell conjures and tethers an additional balloon to the target for
each slot level above 2nd, all of which must be destroyed for the spell to end.
