When holding this glittering opalescent orb you can cast mirror image from it once. The orb creates three additional duplicates. You regain use of this ability after you benefit from a long rest.

The additional duplicates make you even harder to hit. If you have six duplicates, you must roll a 3 or higher to change the attacks target to a duplicate. With five duplicates, you must roll a 4 or higher. With four duplicates, you must roll a 5 or higher. With three duplicates, you must roll a 6 or higher. With two duplicates, you must roll an 8 or higher. With one duplicate, you must roll an 11 or higher.
