You reach out to attempt to touch a creature within range. It must make a Dexterity saving throw. On failure, the target's armor (including natural or magical defenses) becomes soft and malleable, though retaining its form, and provides no protection against attacks reducing the target's AC by 5 for the duration of the spell.   Alternatively, you can touch a nonmagical object that isn't being warn or carried and is no larger than 2 feet in any dimension, reducing its AC and any Strength check required to break it to 5 for the duration of the spell.
