Water Rats

A frigid water rat is conjured and charges up to 60 feet at a target. The target must succeed on a Constitution saving throw. On a failed save, a target takes 3d6 cold damage and is chilled until the end of your next turn. While chilled, the target is vulnerable to ice damage. A creature that is immune to cold damage is not affected by this spell.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d6 for each slot level above 1st.
