The area surrounding that point in a 20-foot radius becomes a powerful magnetic field for up to one minute, with the below effects For any effects within the field which require a saving throw, Tiny and Small creatures have disadvantage, Large creatures have advantage, and Huge and Gargantuan creatures are immune.

• All creatures that start their turn inside the field and are holding nonmagical metal weapons or other metal objects that are size Medium or smaller must succeed a Strength saving throw against your Spell Save DC or be disarmed of those objects, which fly toward the center of the field. Any creatures that succeeded this saving throw have disadvantage on attacks made with nonmagical metal weapons while they remain inside the field.
• Any ranged weapon attacks made with nonmagical metal projectiles have disadvantage if their trajectory passes through the field, unless they are firing directly at a creature or object in the center, in which case the attack has advantage
