For all those working on your second stage of GS Escutcheon, this one can be quite a pain because of the smithing base synth needed and the materials. On top of it being a T1 without doing some extra work. Take it from me, do that LC test to get Artisan temporarily and work on the GP. With LC neck (2), hands (1), body (1), and synth support (3) that puts you right at T2 saving you so much time and pain.
Puts you in Tier 2, then this is fairly easy to complete. In my opinion. absolutely worth the time investment into those Leathercraft items. Jadagnas are a pain to get, so better waste as few as possible.
Working on the goldsmithing RoE, websites claim this to be a 46 sub for leather - i do not find this to be true, with +2 leather torque, guild +1 gloves, adv support it should be tier 2. I am 0 for my last 50 even with all this preparation, or SE hates me.
