Cryo Chill Cut

You brandish the weapon used in the spell’s casting, infusing it with elemental ice , and make a melee attack with it against one creature within 5 feet of you. On a hit, the target suffers the weapon attack’s normal effects, and your weapon begins to rapidly cool the immediate area. If by the end of its turn the creature hit does not move at least 10 feet from the position that it started it's turn, the creature takes cold damage equal to your spellcasting modifier. 

This spell’s damage increases when you reach certain levels. At 5th level, the melee attack deals an extra 1d8 cold damage to the target on a hit, and the additional cold damage  increases to 1d8 + your spellcasting ability modifier. Both damage rolls increase by 1d8 at 11th level (2d8 and 2d8) and 17th level (3d8 and 3d8).
