If you're the industrious melee type, and you're not in a raid guild, Darkmoon Faire offers one of the best neck pieces available to you with this item. You will have to work to get the 1200 tickets to get the item. I have found that farming rugged leather and making rugged armor kits was a fast way to get tickets.

Here is a breakdown:

8 rugged armor kits = 20 tickets.
You'll need 480 rugged armor kits to get the required 1200 tickets. It is completely obtainable with some work, and it is a great reward for the effort.

You can obtain either the Orb or Amulet of the Darkmoon by collecting tickets by handing in specific items. These items can range from Small Furry Paw to Glowing Scorpid Blood as well as many crafted items by Blacksmiths, Engineers and Leatherworkers.

Note: In all of this, the auction house is your friend!

You can gain a head start by solely handing in Vibrant Plumes. If you hand in other low level items you will gain less tickets and require more of an effort with the higher end - so don't do it! A total of 125 Vibrant Plumes is required for 25 turn ins (5 per turn in.) Giving you a total of 300 tickets.

Now you require 900 more tickets. For maximum ticket gain, at 20 tickets per turn in, you have a choice of: 10 x Evil Bat Eyes, 10 x Glowing Scorpid Blood, 8 x Dense Grinding Stones, 6 x Thorium Widgets or 8 x Rugged Armor Kit.

This equates to 45 turn ins, or depending on your choice of item:

• 450 Evil Bat Eyes (45 stacks.)
• 450 Glowing Scorpid Blood (45 stacks.)
• 1440 Dense Stone (72 stacks.)
• 810 Thorium Bar (40.5 stacks,) and 270 Runecloth (13.5 stacks.)
• 1800 Rugged Leather (90 stacks.)

Good luck! ^_^

It depends greatly on your server's economy on which way is cheapest... Typically it's dense stone, but sometimes it's thorium bars.
Here's a quick way to find out how much it's going to cost you per turnin:
Multiply the cost of one stack (20) of each item by the following: 2 for rugged leather, 1.6 for dense stone, and for the widgets, .9 * Thorium Bars + .3 * Runecloth.
Therefore, let's say that on your server, thorium bars cost 3g a stack, runecloth 1g, rugged leather 2g and dense stone 2g.
That means each turn in costs 3g for thorium, 4g for leather, and 3.2g for stone. (for a total of 180g for 1200)
Now you usually will end up using a combination, depending on what is on the AH at any given time, or your own farming skills, but this is a handy tool for those who plan on buying a majority of it.
