Eladrian’s Frigid Wind

A line of freezing cold air 30 feet long and 5 feet wide blasts forth from your palm in a direction you choose. Each creature in the line must make a Dexterity saving throw. A creature takes 3d8 cold damage on a failed save, or half as much damage on a successful one. If a creature fails it’s save by 5 or more, they are frozen and restrained for 1d4 rounds.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d8 for each slot level above 2nd.
