Amulet of the Mirage

(Requires attunement by a spellcaster)
Using an action, this magical amulet creates a silent illusionary duplicate that exactly matches the attuned user and can be mentally directed without requiring an action. The illusion starts in the same space as the user and remains for 1 minute. Any physical interaction reveals the illusion for what it is, and requires a Wisdom (Perception) check against the attuned user's spell save DC to see through the illusion.
