It's the same as the other recipes, just use a pristine polar bear head (I believe it's discoverable).
I tried it with all the right ingredients. Wiki says regular mounted bears are teachable, but not re teachable. First pristine polar bear head I have gotten and now am having trouble mounting it
Ok. Sorry, I don't know where the merchant is that has has the recipe. Doris Jeanette in Ardoris used to have it but I think that changed.
@Aldo According to SOTATraders.com you should try Etceter. Arakius Endiki, the decorations merchant has it.
