Depthsurge

You conjure a powerful explosion of water, scattering creatures effected by it. Choose a point within range. Creatures within a 10-foot radius sphere centered on that point must make a Strength saving throw. If a creature fails this saving throw, it takes 4d10 bludgeoning damage, is knocked 15 feet away from the center of the explosion, and falls prone. On a successful saving throw, the creature takes half damage and suffers no additional effects.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d10 and the distance pushed increases by 5 feet, for each slot level above 4th.
