Does the subject have to see you to be charmed by you?

[LavaRox]

So I have tried to research this question, but it always gives me threads about charm spells breaking Invisibility.

I wanted to know if I am going into a situation and I have Greater Invisibility, and I want to charm person/monster (while remaining invisible, of course) does the charm still work? In order to perceive you as a friend, do they only need a friendly voice to charm them, or must they SEE YOU as a friend? This sounds more like a GM interpretation question? Just wanted some collective thoughts, and if someone has a legit Core Rulebook answer, all the better

No.

They don't need to see you.

(Unless you don't speak their language and you have to pantomime)

Being blind/closing your eyes doesn't make you immune to charm.

Spells that require that the target see you, or the effect, will tell you in the text, usually with a subschool like glammer, figment, pattern or something similar.

The spell "Raiment of Command" is a charm like spell that requires the target see you.

The range is really short and people will still see the spell, you may be better off with the reach metamagic feat than with invisibility.
