Water Drake

Water pools at a point you can see within range and swells into the form of an aquatic, serpent-like dragon. When the dragon appears, it immediately unleashes scalding steam in a line that is 5 feet wide and 15 feet long, in a direction of your choice. Each creature within the area must make a Dexterity saving throw. On a failed save, a creature takes 2d6 fire damage. On a successful save, a creature takes half damage. This fire damage ignores resistance granted by being underwater. On each of your turns for the duration, you can use your action to repeat this effect.

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