After you see a creature or object within your relative size with a flexibility of 1 larger or smaller, by spending 1 mimicry charge you can use your reaction to mimic its appearance by modifying the structure and color of your opperating system. For the next hour or until you dismiss it.
You make yourself, including your clothing, armor, Weapons, and other belongings on your person, look different until the effect ends or until you use your Action to dismiss it. You can seem 1-4 feet shorter or taller and can appear thin, fat, or in between. You can't change your body type, so you must adopt a form that has the same basic arrangement of limbs. Otherwise, the extent of the Illusion is up to you.
The changes wrought by this effect fail to hold up to physical inspection. For example, if you use this effect to add a hat to your outfit, Objects pass through the hat, and anyone who touches it would feel nothing or would feel your head and hair. If you use this effect to appear thinner than you are, the hand of someone who reaches out to touch you would bump into you while it was seemingly still in midair.
To discern that your appearance is fake, a creature can use its action to inspect your appearance and must succeed on a Intelligence (Investigation) check against your mimicry save DC.
