So i have scoured the internet in hopes of finding an answer to these question, but all I can find is people almost answering the questions but not quite.
First - Using disguise self to make yourself look like someone else, any random guy is fine, and talking to someone when do they get a saving throw? If ever. They are just talking. No touching, no felling, just conversation back and forth. The person does not know the person that the image appears to be, two total strangers talking to each other.
Is talking considered interaction? If talking is interaction does he just get one save for talking as an interaction and then if he fails that one he gets no more saves? Or does he get a save every round or in some sort of time frame as he is continuing to interact with it by talking?
