Enchance hack

Hi, i have been trying to do some enchance hack using WPE. But, so far i just able to capture the packet that used to enchance and in result i can enchance in every NPC not just blacksmith, i can even enchance at quest board. I have been trying to do this hack for almost 1 week and i'm starting to think that is it even possible to do enchance hack?
Lastly, sorry for my bad english

actually if u master using WPE its not impossible
Experience+Some Tools+Brain+Some Stuff in Google= Just A Piece of CAke ;)

It cannot be done actualy.
Unless that we can find a great exploit in game.
