When patch 4.3 first launched, the market price for Chaos Orbs on my server was about 400 gold. It didn't take long for the price to fall, though -- as of Dec. 4, the average market price is about 56 gold. Frankly, that's much lower than I'd have expected them to get so soon.
Don't get me wrong, though. I'm not complaining. Quite the opposite: I'm excited. That's because low-priced Chaos Orbs are a tremendous opportunity out there for crafters of just about all stripes.
The current supply
Do you have a large supply of Chaos Orbs sitting in your bags? You're not alone.
As things currently stand, most Auction Houses seem to have a surplus of Chaos Orbs. This shouldn't be too surprising. We've known for quite some time that Chaos Orbs would be going BoE in patch 4.3. A lot of people who didn't have immediate profitable uses for the orbs (such as tailors) saved them up. And now that they can sell the things, they're trying to do just that.
