After completing your island expedition and second foothold, head back out to your third and final zone to quest in. Note that any legendaries you were using to level have become inactive and are merely stat sticks now. Feel free to replace them with quest gear as you obtain it. Before heading out, feel free to send your three champions out on new missions!
The main tool for any serious gold maker is TradeSkillMaster. It is an addon suite with a desktop application that downloads price data and allows you to create rules for easy crafting, mailing, shopping and posting your items on the auction house. It has a premium service that includes e-mail notifications for great deals and importing great deals as a shopping scan.
A very middle of the pack one, I'd say, if not slightly above average. While the unsocketing power is very minor in both profitability and usefulness, the daily cache of gems is a very nice, pretty low maintenance way of getting a decent surplus of gems each day, very worth adding to any daily rotation. Fantastic for keeping your raiding main's gem slots consistently filled, and yet still having an extra supply to sell. Naturally, however, it's limited per day so you can't really extract a tonne out of it but the flavour of the item really melds with JC well and is something I think should have been part of it for a long time, but still not very exciting nor are gems particularly relevant anymore, sadly, so it loses some points there.
Although the Battle Pet Trainer will only offer to teach you your race-specific companion, it is possible to add all of these pets to your collection. You can either find them in your faction’s auction house or you can create a character of the race whose pet you would like to learn. Using your new character, you can seek out any battle pet trainer in major cities. After you learn the pet, you can delete the character; the pet you learned will not be removed from your collection.
