Waterbomb

With a swift gesture, you conjure a swirling mass of water that coalesces into a shimmering orb. You hurl the Waterbomb at a point within range, where it bursts upon impact, unleashing a deluge of water and an explosive wave of force. Each creature within a 20-foot radius of the explosion must make a Dexterity saving throw. On a failed save, a creature takes 4d8 bludgeoning damage and is knocked prone, as the rush of water cascades over them. On a successful save, the creature takes half damage and is not knocked prone. Additionally, the area becomes difficult terrain as the water pools and floods the ground, lasting until the end of your next turn. For any creatures sensitive to water (such as those with the Fire subtype), the Waterbomb deals an additional 2d8 fire damage, assuming they are within the radius. As a bonus effect, you can choose to use the Waterbomb to extinguish fires in the area, immediately putting out any flames, even magical ones, within the radius of the spell.
