How does the spell Mind Blank interact with shapeshifters and other forms of false identity?


Mind Blank states:

Until the spell ends, one willing creature you touch is immune to psychic damage, any effect that would sense its emotions or read its thoughts, divination spells, and the charmed condition. The spell even foils wish spells and spells or effects of similar power used to affect the target’s mind or to gain information about the target.

How does the spell Mind Blank interact with shapeshifters and other forms of false identity?

Are all aspects of their identity protected, or just information associated with their true form/name?

  • For example, can a guard give a description of a changeling’s persona via sending since it is not their natural form?
