Title sort of states it all, but I was thinking it would be a nice, and hopefully balanced benefit to being a patron. I'm not one at the moment, but have been thinking of picking it up again, and while it wouldn't be horribly useful, it would be nice. Probably slightly less useful than the class trainers.

How I'd go about it - either you'd get the skill as a perk of having that profession, or give them all out to every character. Just a thought, but personally I'd love it.
