dark helmet + propeller with superior is 100% sure titanium sword

and gray steel bracers can't be made with titanium sword + red jade necklace
as gray steel bracers is titanium and not titanium/jade

so if you want to compound gray steel bracers, either use titanium sword + titanium sword (superior) or titanium sword + red jade necklace (junior)

anyway, i never make it as its not worth it, fails too much. Jade helmet is a lot easier when you have superior. Result is either jade helmet or a common stone :D
