Things You'll Need
Instructions
Click the dungeon finder button on the bottom of your screen to launch the pop-up dungeon finder window. This button becomes active when you reach level 10, at which time you are eligible to queue for Ragefire Chasm.
Select your role. You can choose tank, healer or dps. Make sure that you have adequate gear and skills for the selected role.
Choose the "Random Dungeon" default to queue for a random dungeon of the appropriate level for your character. You also have the option of selecting level-appropriate specific dungeons, but you will not get credit towards "Looking for Multitudes" or the Perky Pug from specific dungeon queues.
Wait for the random dungeon finder to put a party together. You can quest, travel or visit the auction house while in a random queue, but you cannot join groups, raid or do battlegrounds. Click "Enter Random Dungeon" when offered that option by a pop-up window that appears on your screen when your group is ready.
Continue completing random dungeons until you get the achievement "Looking for Multitudes." The Perky Pug will appear in your mailbox a few minutes after you complete the achievement.
