While wearing this amulet, you can use an action to cause a duplicate of yourself to appear in a space within 5 ft of you that you choose. The duplicate is a creature, uses all the statistics of the creature it duplicates, and possesses copies of all of the creator's nonmagical equipment. Any magical weapons or armor worn or carried by the creator are instead replicated as nonmagical versions of the same items for the duplicate. The duplicate acts on its own initiative, and obeys its creator to the best of its ability. The creator can have the duplicate use class features such as spells or combat maneuvers; however, doing so uses the creator's resources for these actions. For example, having the duplicate cast a 1st level spell requires the creator to expend a 1st level spell slot. The duplicate lasts for 1 minute or until it is reduced to 0 hit points, at which time the duplicate and all of the equipment generated during its creation vanish.
If the creator of the duplicate is reduced to 0 hit points while the duplicate exists, their consciousness is transferred to the duplicate, which becomes the real version of the character. Their original body disappears, and all magic items in their possession are transferred to the new body. This process is very disorienting, causing the character to be stunned until the end of their next turn.
Once the amulet has been used, it cannot be used again until next dawn.
