Hydaelyn

Choose a point within 60 feet to generate a powerful magnetic field. You may choose to attract or repel metallic objects and creatures within a 30-foot radius, which are moved instantly. Metallic creatures or those in medium or heavy metal armor must make a Strength saving throw or be pulled or repelled 10 feet and take 3d6 force damage, or half as much on a successful save and will remain unmoved. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d6 for each slot level above 5th and the radius increases by 10 feet.
