Bloat

You cause the gases within a creature you can see within range to expand rapidly. The target makes a Constitution saving throw, taking 3d10 Necrotic damage on a failed save or half as much damage on a successful one. If the damage that the creature takes equals or exceeds its Constitution ability score, the creature floats vertically 5 feet and remains suspended until the start of your next turn. The target can move only by pushing or pulling against a fixed object or surface within reach (such as a wall or a ceiling), which allows it to move as if it were climbing. When the spell ends, the target floats gently to the ground.
