This question already has an answer here:
Minor Illusion can be up to a 5 cu ft in dimension as described in the spell. Any thing that touches the Illusion goes through it like it would a hologram then, right? Can you then hide inside the 5 cu ft dimension the Illusion occupies? While not truly invisible can one at the least get advantage to Stealth from it?
In the same vein, can you then cast Minor Illusion on yourself to make yourself look like a part of the environment to get an advantage on Stealth?
I had an idea for a Ninja/Sorcerer to Quicken cast Prestidigitation (flash/smoke bomb) and Minor Illusion together a la "Ninja Vanish" and to look like I've disappeared but still be there waiting for them to leave thinking I gave them the slip. Yes Misty Step can technically do that but I want to save that as a panic button to save myself from a potential early religious or infernal experience.
