But you cannot change the shape of your body, so your deformed look must have limbs or similar physiological structures. In addition, the range of influence of the illusion is up to you.

The changes made by this spell cannot cope with physical inspections. For example, if you use this spell to add a hat, real objects will pass through the hat, and anyone who touches the hat will not be able to touch anything or touch your head and hair. If you use this spell to make yourself thin, and someone touches you with his hand, his hand will look like it is touching the air.

If a creature wants to tell whether you are disguised, it must use an action to expose your disguise and make an Intelligence (investigation) check against your spell save DC.
