You throw a small orb underneath or at the feet of a creature or object of size large or smaller. The target needs to succeed on a Dexterity saving throw, if not willing, or the orb will flatten and turn into an explosive springboard and harmlessly launch the target up to 20 ft. into the air. Creatures or objects of a tiny size will have the launch height be doubled.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the launch height is increased by 10 ft. per level.
