You summon the spectral head and coils of an abyssal leviathan, thrashing in a massive area.

• Each creature of your choice in the sphere must make a Strength saving throw. On a failed save, they take 10d10 bludgeoning damage and are restrained as water coils crush them.

• Restrained creatures can repeat the save at the end of their turns.

• While concentrating, you can cause the leviathan to shift 20 feet as a bonus action.
