Here is how I did all my EoK armors with my skills being pretty low....
I looked at the recipes for each of the items I wanted to make.
Gathered them by farming or buying in Bazaar (Caster gear and tank gear... you really only need enough to make one item so don't buy "extra" components)
Go to the DB store and look for the potion
Draught of the Craftsman. The effect is "Increases your chance to salvage tradeskill components by 100%".
It is 2500 DB. I know its 2500db, but the time, item farming or buying, skilling up is WAY more than what the potion costs.
1 -Put all TS items into bags and go to the loom, forge (or whatever crafting station you need to use)
2 - Drink the potion (2 hr duration) and start crafting.
3 - Since you never made the item you need to do the combines manually
4 - two things happen, you get skill ups as you attempt to craft, on each "fail" you get all the components back so you can try again.
5- eventually you will craft the item you wanted to make.
The best practice is just to get everything ready so when you get to crafting, maximize the use of the potion.
Happy crafting!
