Tweaked from 5eYou already know this as 5e Ray of Frost (likely) — Like Ray of Frost it's an at-will cold attack that slows the target, but instead of a ranged beam it rides on a melee weapon hit and only deals its bonus cold damage if the target then stays put — so it plays like a Booming Blade reskin in cold's clothing.
On a melee hit, impose 1 slowed level; if the target doesn't move 5 feet before your next turn, it takes 1d8 cold damage.

As part of the action used to cast this power, you must make a melee weapon attack against one creature within your reach, otherwise the power fails. On a hit, the target suffers the attack's normal effects, and gains 1 slowed level until the start of your next turn, as the cold energy seeps into its being. Additionally, if the target doesn't move at least 5 feet before the start of your next turn, it immediately takes 1d8 cold damage, and the power ends.

This power's damage increases when you reach higher levels. At 5th level, the melee attack deals an extra 1d8 cold damage to the target, and the damage the target takes for not moving increases to 2d8. Both damage rolls increase by 1d8 at 11th level and 17th level.
