Fanny Pack of Concealment

Sym-Tech Item, uncommon (requires maintenance/attunement)
While wearing this fanny pack of sym-tech, you can use an action to generate the Disguise Self power from it at will. The power ends if the hat is removed.

Disguise Self: The fanny pack bends light around yourself—including your clothing, armor, weapons, and other belongings on your person—and project a holographic image of that changes your appearance until the power ends or until you use your action to dismiss it. You can seem 1 foot 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.
These changes fail to hold up to physical inspection. For example, if you use this power 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 power 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 you are disguised, a creature can use its action to inspect your appearance and must succeed on an Intelligence (Investigation) check against a power save DC of 13.
