The next time you hit a creature with a melee weapon attack during this spell’s duration, your weapon is sheathed in frost, and the attack deals an extra 1d6 cold damage to the target. Additionally, the target must succeed on a Constitution saving throw or be restrained until the spell ends.
A creature restrained by this spell makes a Strength saving throw at the end of each of its turns. On a successful save, it is no longer restrained.
you cast this spell using a spell slot of 3rd level or higher, the cold damage increases by 1d6 for every slot level above 2nd.
