lol better way of success:

Skeleton iron sword + refined white silvery = knight's helmet
knight's helmet + vertical wing = pirate rip/arabia knife/ghost halberd/goblin halberd/rip iron sword/war halberd/king halberd

or

silvery armor + propeller = same results (no king halberd here)

or

skeleton iron sword + wooden pedals = (war halberd & rip iron sword will be rare here)

<< I recommend you to use superior alch for a better success and less fails on this recipes ;) >>
