Ok, let’s do a 5e spell. Haven’t done that in a while.
Casting Time: 1 action
Range: 50 feet
Components: V, S, M (a vial of water)
A small pinpoint of light appears within a point at range. The light pulses and then explodes bathing a 10 foot in diameter area in light and frost. Each creature in the area must make a Dexterity saving throw. A target takes 2d8 cold damage on a failed save and is restrained until the end of its next turn by ice, or half as much damage on a successful one and is not restrained.
At Higher Levels: When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d8 for each slot level above 1st.
