I do but jade helmet was used as a confirmed ingredient in jade loricae. But snow cuffs + poison knife + jade helmet should have been a jade loricae since emerald boots have no titanium.

I did however use my spare emerald boots to successfully make a jade loricae with emerald boots + knight war boots + black wand + book 3 so everything worked out many alchemy book 3's (and item mall points so bye bye gold card and eremote for next month) later :D
