Two unnerving vestigial arms that somewhat resemble a grasshopper's have grown on your upper abdomen just below your primary arms. They are weak and only reach up to the elbow of your primary arms, but are capable of holding and manipulating small objects (such as spell-casting focuses) that weigh up to 1lb or less. Additionally, you can perform one additional bonus action attack with a weapon that has the light property and weighs no more than the arms hold. You can not apply weapon mastery on this additional bonus action attack.
