Actually, it's not that difficult, just time consuming.
You need to start with:
Robe x1 Bronze Subligarx1 Which can both be bought at vendors.
Then you need another set of eq, I had Wool Hoses and a Wool Doublet. Can be bought then resold from AH.
You need your AF 1 piece that is, the AF1 weapon does not count. The Gaudy is lvl 50, as are the other JSE armors, at 50 you can gain af so you should be getting it anyways.
The only tricky part is the rare/ex subligar 'Ophiuchus subligaria'. Basically, this is the quest. Like anything else it will not be a walk in the park, but it's all luck; I got mine on the first BST Fomor kill. With some help from friends, patiences and effort, this quest is well worth it :) and fun too.
