It's pretty much getting about 12%-18% quality off hasty/basic touch with Inner Quiet, then popping Innovation, Great Strides and oneshotting the bar with Byregot's Blessing (guaranteed 100% at 18% quality assuming base HQ was 1%, and no Good/Excellent modifiers affected quality).

However, if you're just doing same level crafts, then you can skip on Blacksmithing to 15. I would suggest getting all to 15, but if you want to save every penny possible then you can skip ingenuity until you plan to craft 1/2 star equipment.

Also, the 1000 character limit is a bit ridiculous. It should definitely be doubled so posts aren't cut so short.
