The Earthcrawl Mines' boss is easy on a warlock. Make Brann healing spec and let him get aggro and tank. Use your Imp pet's Singe Magic to cleanse yourself of curses. Stay in the center near the boss and watch for mine carts. DPS the boss only with your flamethrower.

Since lock rocks and healing pots don't share a CD, Brann almost always has 3 of his potions set out for you to walk over and your defensives to mitigate damage, it is really easy to stay alive on this fight.
