The Orb of Deception

I think one of the best things about the expansion for World of Warcraft is that at level 70, you can do a lot of things alone that you couldn't do at 60. Thankfully, no one bothers to do some of these things, so if you pull it off, you can make some serious cash.

Enter, the Orb of Deception. It's a trinket that transforms a member of one faction to look like a member of the other faction. I know, it's totally useless! But the "cool" factor, or the "I just have everything else" counts a lot here. These things go for 500 gold, easily. It's a rare find on the Auction House these days.

So how do you get it? Head to the Dire Maul Arena. Keep an eye on you chat window and wait for Skarr the Ubreakable or Razza to yell something: that means they are at the arena (takes a few hours to respawn, so go kill time mining or something while you wait, or farm the instance). Soon as one pops, go and kill it! They have about 10% chance to drop the Orb, but will always drop SOMETHING decent. Azeroth blues sell for TONS more than Outland blues, so you are guaranteed some gold!

If you aren't a caster who can kite, or a hunter, you may want to take a friend. Of course, if you have decent enough gear, burn your cooldowns and take some potions, you'll probably be alright.
