Ask

Usage: ask <monster> [about <subject>]

With this command you can ask a monster about some subject. If it knows
anything about it, it will respond in some way, usually by saying
something. If you don't specify what you want to ask the monster about, you
will simply greet it and ask how it fares. This will usually give you some
idea about what else you can ask the monster about. You should always use
this command when trying to get information from a monster.
