Be warned that players will occasionally list items in the Auction House that are sold by vendors. This typically applies to limited sale quantity items or items in remote, harder to reach locations. Items from Outland that advance certain skills (such as books for training Cooking or First Aid past a skill of 300) are typical. These items are notoriously listed for 2, 3, or even 10 times their vendor purchase-able price. Using an add-on such as Auctioneer Advanced can forewarn you of such a tactic. You should ONLY buy such items if your server is so full and busy that you simply are unable to acquire the item on your own. Otherwise, wait for the vendor to re-stock (usually takes about 20 minutes to 1 hour depending upon the vendor). You'll save yourself a considerable amount of money. See Buying Items from Vendors for Resale below for more on this.
Excess Potion of Accelerated Learning: Acquired in your Garrison (part of the Warlords of Draenor expansion), this gives you a 20-percent bonus to experience from killing monsters and finishing quests. It lasts one hour, but you can buy it multiple times and use it back-to-back. Alliance players buy it from Sergeant Crowler, horde players buy it from Sergeant Grimjaw. Does not work above level 99.
As the war in Azeroth rages on, the champions of the Horde and the Alliance look to their in-game friends for help. Whether it’s levelling up for experience, gearing up for combat, or mounting up to see the world, World of Warcraft is always best enjoyed in groups, however big or small. If you have guildmates, friends, or family who haven’t been in Azeroth for a while, let them know they can play for free this weekend.
In addition to questing and running dungeons in the Broken Isles, players should also remember to visit their class hall, which is like the garrisons from Draenor, but themed around your character’s class.The quest lines in your hall provide valuable experience and open up important features, like artifact weapon upgrades, that will drastically up your character’s power.
