Have a try at this formula~
I compound Skeleton Iron Sword + Black Jade to make Footman's helmet~
(Skeleton Iron Sword = Iron Net Boots + Wolf Tooth + Iron Net Boots)
(Black Jade obtained from Ice Berg Vacuum spot on 3rd Floor)
I usually get Footman's Helmet 1/3 times~
(primary alchemy lv 8)
Muu~ -_-
