Blackwing Lair is a 40-man vanilla WoW raid, that can easily be completed by a group of a few level 85's. This is an easy raid to farm gold, and Elementium Ingots for the legendary Thunderfury weapon. Getting attuned for BWL lets you enter the instance a lot quicker. Here's how you can get attuned for Blackwing Lair!
Find the Scarshield Quartermaster
The Scarshield Quartermaster is a non-elite mob that patrols outside of Blackrock Spire. Looting this mob gives an item that starts the quest Blackhand's Command. Click the item to start the quest, and follow the path up to the Blackrock Spire instance portal.
Slay General Drakkisath
The next step of your Blackwing Lair attunement quest is to click the orb of General Drakkisath. The General is the final boss in Upper Blackrock Spire, and you can get to him by taking the left staircase and door after entering the spire. After defeating the General and clicking the orb you will be attuned for BWL.
Getting to Blackwing Lair
The entrance to BWL can be accessed from within UBRS, but after being attuned you can quickly enter the raid by accessing the orb at the end of the hallway outside the Blackrock Spire instance. Simply click on the orb, and you will be teleported to Blackwing Lair!
