Baja Blast

You fire off a concentrated beam of baja. The beam is a straight line originating from you 30 feet in one direction. Any creatures in the line must make a Dexterity saving throw or take 1d10 cold damage, half damage on a success. After the beam hits, it remains in place until the end of your next turn, and any creature that enters the line for the first time on its turn, or ends its turn in it must make the saving throw.

At Higher Levels. When you cast the spell with second level or higher, the beam lasts an additional round for each spell level above first.
