You create a image of an object within range that lasts for the duration. The illusion also ends if you dismiss it as an action or cast this spell again. The illusion only appears and is interactable to the target you cast the spell on (20ft radius) and everyone else sees it as non-existent. The object can be whatever you imagine, even a creature, as long as it can fit in your hand. It can make any sound you like, as long as it doesn't exceed 130 decibels. The illusion can change throughout it's existence.
If a creature uses its action to examine the image, the creature can determine that it is an illusion with a successful Intelligence Investigation check against 18DC. If a creature discerns the illusion for what it is, the illusion becomes faint to that creature creature, but no other creatures who were affected.
