Crystal Ice Spears

Three jagged pillars of ice forming three lines 100 feet long and 5 feet wide blasts out from you in a direction you choose. Each creature in the line must make a Dexterity saving throw. A creature takes 8d6 cold damage on a failed save, or half as much damage on a successful one.

The ice freezes water in the area.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, you can create an additional pillar of crystal ice. 

The mythic mage of Legend, Cameron the Clairvoyant created this spell while in the lands of Dragons Dogma, while spell-syncing with a Sorcerer party member to take down the fabled Daimon of Bitterblack Island.
