You reach out and touch a suit of metallic armor or a metallic shield. An unwilling creature can make a Dexterity saving throw to avoid your touch. Whilst the spell is active, metallic objects, weapons, and ammunition are drawn to the target. Attacks with metal weapons and ammunition against the target have advantage, and ranged attacks with metallic weapons and ammunition against other targets within 15 feet of the target have disadvantage. In addition, all loose tiny metallic objects within 15 feet are pulled 5 feet towards the target each round, and stick to it if they reach the target. A dispel magic or remove curse spell cast on the armor ends the effect.
