As part of the action used to cast this spell, you must make a melee attack with a weapon against one creature within the spell's range, otherwise the spell fails. On a hit, the target suffers the attack's normal effects, and takes cold damage equal to your spellcasting ability modifier. Additionally, if the attack hits, you may move up to half your speed without provoking attacks of opportunity.

At 5th level, the melee attack deals an extra 1d8 cold damage to the target. Increasing again by 1d8 at 11th level and 17th level.
