Frozen Fists

Prerequisite: Intelligence of 13 or higher

You may use a bonus action to start absorbing heat through your hands. While absorbing, your Unarmed Strikes deal an additional 1d4 cold damage slowing your target by 10 feet for one round. This effect stacks with similar effects such as Ray of Frost, but not with itself. This absorption lasts 1 hour or until you use a bonus action to stop the effect.
