• Each creature in a 20-foot-radius sphere centred on that point must make a Constitution saving throw.
• A target takes 7d6 Bludgeoning damage on a failed save, or half as much damage on a successful one.
• This damage increases to 9d6 if the affected creature is submerged in a liquid.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.
