I vaguely remember that I have seen a Dungeons and Dragons subclass, variant or feat that allowed a spellcaster who studied Genies or was related to them to cast spells by using spoken wishes as verbal component, instead of speaking themself.
I would like to update it to 5e, because I really like the concept, but first I need to find the original material.
I suspect it was 3.5 material, but I'm really not sure. It could be an internet material, friend's book, or magazine in a game shop, I honestly can't remember. What source is this feature from?
