This spell uses biting cold to make a metal or stone item brittle and easy to shatter. The item's hit points are permanently reduced by a number equal to your spellcasting level, and Strength checks to shatter or break the item within 1 minute of the spell's casting are made with advantage. If the item isn't shattered, it can be repaired as normal.
