If you love soloing and need a character for farming, I would suggest you create a hunter. They are very good solo and they can easily take out stronger mobs with the right combination of skills.
Then once you have all the lapis you need you to build your orc, full REC is always the way to go. Safe lapis (REC) are the most expensive to buy whereas Wise and Mystic lapis are less than half the price if not more!
However, if you are willing you can always level your orc and just ask someone to help you farm
I hope that helps!
