Creeping Frost

You draw a wintry death from the ground beneath a creature you can see within range. At the end of the creature's next turn, the ice lashes toward them, dealing 6d6 cold damage. For every 5 feet the target has moved since the spell was cast, the damage is reduced by 1d6.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d6 for each slot level above 2nd.
