Lady of the Deep Water's Torrent (5e Spell)
From D&D Wiki
|Casting time:||1 action|
|Duration:||1 minute (concentration)|
By communing with a minor goddess of water, you create an up to 180 ft. long, 60 ft. wide, 10 ft. tall torrent of water in one direction of your choice starting from one location that is within range. Any creatures in this area must attempt a Strength saving throw. On a failure, they take 3d6 bludgeoning damage and are moved 60 ft. in the direction the water flows away from its source. On a success, they take half as much damage, and are moved half as far. A creature may choose to halve the damage they take by automatically failing the saving throw.
