Heya. I'm going to be honest — on review, wand making is described as a "complex and mysterious branch of magic". Hermione herself, as far as I'm aware, please correct me!) doesn't know how to make a wand.

So I'm not sure how Wrathion would gain these kinds of skills to produce the article. As far as I know, Wrathion himself doesn't know how to make wands of any kind, so even if we go by non-HP rules — I don't see how he'd be able to do it...
