Yes this is a dumb spell inspired by the Mario mechanic where you get to stomp your enemies and cave their head in. Such violence for a kids game when you think about it.
I was designing some proper gravity spells for my Patreon, but decided to have fun with it and this one had some meme potential, so here it is.

3rd-level transmutation (Sorcerer, Warlock, Wizard)
Casting Time: 1 reaction (that you can take when you fall or when you see a creature within range fall)
Components: S, M (a small mushroom)
As a reaction to falling or to seeing a creature fall, you can enhance its velocity, causing the area where it falls to crack under pressure. When the creature reaches the ground, it takes falling damage as normal, then it and all other creatures within a 15-foot radius of it must make a Dexterity saving throw, taking 4d8 magical bludgeoning damage on a failure and half on a success. If the creature lands directly onto another creature, it instead bounces up 5 feet before landing next to it and taking no fall damage. All other creatures must make the saving throw, taking 6d8 instead of 4d8 magical bludgeoning damage on a failed save and half on a success.
At higher levels: When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d8 for each level.
