Get Item from Enchant to Vellum
 

If I have an Enchant (i.e. http://www.wowhead.com/spell=158914/...ritical-strike), is there an API function that will tell me the item it creates (i.e. http://www.wowhead.com/item=110638/e...ritical-strike) when applied to an Enchanting Vellum?

I don't think this is something Blizzard would bother making an API function for. It's likely you'll need to find a library or build a lookup table yourself.
