Of course, it can be attached, but the properties of the enchanted new orb will overwrite the original enchantment. A piece of equipment can only have one enchantment attribute. For example, the original enchantment of 15 force is now attached with a 30-force orb, and 15 force disappears. Whether it is a card or a orb, the essence is the same. The card needs an enchanter to enchant, and the ball is made of cards and some materials by the enchanter.
