Now that we have more than a couple daily tasks out there, I was thinking that
the tasks could be categorized. If you end up killing a certain number of
kings or such as work... you've become a novice Assassin. Killed a criminal ?
you're a neophyte bounty-hunter. Crafting quests could lead you to be trained
by appropriate craftsmen.. the idea is only roughly fleshed out. But after
you've started in a profession, you need to be trained under a master.
You have various npc professionals running around Arelium so maybe they could
be incorporated somehow? Once you start apprenticing to this Master in the
profession, They'll give you various related tasks that could simply be
reworded pre-existing jobs with a couple others thrown in. Ideally
they'd increase in difficulty as you advance through the labels of this
profession (novice, journeyman, master)
I'd think that a skill would be involved. Cooking seems like a good example
of a skill related profession. You become a master chef upon completing
all the jobs.
