Can fire be trained beyond 20? Good luck. Only another 'knowledable' player can help you. It cannot be determined by brute force, determination, or in game semantics. It is simply a 'secret' that is not shared. Again, dissapointing.
This means you could have something more interesting to do other than wandering in search for good conversation, NPC aren't infinite, and if you're smart most of the secrets can be
discovered with no big efforts (another kind of issue is when you have a **** note that someone doesn't want to give you back.....).
