Bubble Breath

You bathe the enemies in a powerful water breath attack. Each creature in a 5-foot cone must make a Dexterity saving throw. A creature takes 1d4 cold damage and is restrained on a failed save, or only the 1d4 cold damage on a successful one.

The restrained creature will remain restrained until the start of it's turn.

At Higher Levels. When you cast this spell using a spell slot of 1st level or higher, the damage increases by 1d4 for each slot level above 0. And the range increases by 5ft at 5th and 7th level.
