My characters are all set up with a purpose, spreading crafting across 4 characters. My goal is to have a master level crafter for every craft. My DK provisioner brings in 2000 gold a week, without even trying, my thief alchemist brings in good coin from a variety of sources, I have an Orc Sorcerer just getting started in Enchanting, and my main is CP250 and set up as supply source. All of my durable goods is being made by an Orc Templar who had a career in the military and gained 48 levels, just so he could get as many skill points as he could. Now he is nearly done with his studies, after mastering in Provisioning, Clothing, Woodworking and 47 in Blacksmithing. Still have a few things to research, but very soon, he will retire to being called upon occasionally as needed only for his crafting.
It's taken me a few months to get this far, and I'm thinking of something to reward myself and/or reward him (no crown items). Maybe a small little house near a good crafting area? New clothes (which he would have to make), or maybe get his Nordic bath towel dyed. (He has some nice tattoos he never gets to show off while in armor)
What have you done when your crafting characters have reached Master?
