Currently (as of 1.23.07) 294 + 8% tinkering skill, Salvage 3, Tinkering Mastery 1. It's past the max chance for success on all AAAA tinkering combines, and except for fletching I can do all the subcombines too. Send Snibbly a tell with inquiries, I'll do most all combines for the supplies plus whatever you feel is an appropriate donation.
