If you've taken up the tedious (yet profitable!) subprofession of mining, initially the leveling
process may seem EXTREMELY slow to you.
Well, here's something not many people realize. After you mine an item, make sure you smelt it
as well. While you may only receive 1 XP point for mining an individual mining point, you
receive another point for smelting the item! Many people who are merely trying to mine simply
sell off the copper tin etc, and never smelt it.......while they could be doubling their XP by
smelting.
A helpful tip I was shocked not many people knew about.
