Rimegrip

Your touch leaves a coating of frost on an object or surface. A 5-foot square of nonmagical material becomes slippery with ice. The area is treated as difficult terrain, and creatures entering it must make a Dexterity saving throw, falling Prone on a failure.   If cast on a metal object, it becomes brittle for the duration. Weapon attacks made using it deal 1 less damage. If you target a worn or carried item, the creature wearing or carrying it can make a Dexterity saving throw to avoid the spell.   The damage reduction to metal weapons increases by 1 when you reach 5th level (2 less damage), 11th level (3 less damage), and 17th level (4 less damage).
