The hag creates an illusory duplicate of herself, which appears in its own space. As long as she can see her duplicate, the hag can move it a distance equal to her walking speed as well as make the illusion speak on her turn (no action required). The illusion has the same statistics as the hag but can't take actions or reactions. It can interact with its environment and even pick up and hold real objects. The illusion seems real in every way but disappears if it takes any amount of damage. Otherwise, it lasts until the hag dismisses it (no action required) or can no longer see it. If the hag uses this lair action to create a new duplicate, the previous one vanishes, dropping any real objects in its possession.
