Weapon Smithing - Easy EXP.

Craft 15 of everything for the free mastery weapon smith rewards exp until you get to the point you can craft golden arrows. Golden arrows cost 1 small gold ingot to craft and craft faster than weaponry. Gives a little bit less exp, but saves time and ingots, so it's better in the end.

Only shitty thing is trying to sell them. If there were a "sell all" button, it wouldnt be bad.
