I had already acquired the Gnarled Wood and Elaborate Hinge, all I needed was the Blacksmithing skill. I ran over to Abysmal and got my skill up to 109 before I lost patience. I will never be a Grandmaster skiller... :-P
I combined the Insert, hinge and wood in the forge with the little skill I had and no geerlok. It worked! And I got a message that I could no longer advance my skill with the combine. The trivial is way lower than Alla lists.
