Use and abuse prestidigitation. Annoying dog? here puppy, the best steak you ever tasted. need to ask the guards again? Change my clothes. plot exposition? minor cube of illusion. Between that and mending I have my GM debating firing my bard after only 3 sessions of curse of the crimson throne.
True though the disguise kit would take more time. I am so far. part of my GMs annoyance is that a lot of the names of the NPCs are clear hints as to their purpose and if you speak German and some Latin it makes it VERY obvious what the next plot point will be so I have been banned from translating the names from now on.
