The Blood Furnace
The Blood Furnace is the next step when it comes to instances. The entrance is above the Ramparts and requires a different route to get to, though it's still in the same area. Once inside, you're charged with finding out what's going on... and, of course, get some loot.
The first boss you'll run into is the Maker. The Maker is a giant undead guy who wanders around, uh, making things. He's a fairly easy fight, actually, and shouldn't be much of a struggle for most normal groups. Mostly, groups will want to just shoot him until he's dead. Not really much of a strategy for this guy. Put a foot into his keister and be on your way. The next fight is where you really run into trouble.
After making the Maker, you head on towards Broggok. Broggok is considerably harder to deal with than anything you've played against so far. Now, you can't really say that it's all just Broggok, that would be unfair. The difficulty of the fight probably has a little something to do with the fact that he summons wave after wave of Fel Orcs to kick you in the head. However, if you manage to survive the waves, then Broggok isn't particularly that difficult to kill.
Finally, to finish the Blood Furnace, you have to face Keli'dan the Breaker. When you get to Keli'dan's area, you'll see him in the center of a circle of Fel Orc warlocks. When you begin the encounter, you must first kill his Fel Orc buddies before Keli'dan will join the fight. The one thing to watch out for with this boss is that he constantly casts high damage area spells. He will fire one off in a cone that does between 2 and 3 thousand points of damage and he has an all-around AoE that does between 4 and 5 thousand points per hit. Other than the extreme damage, he's a pretty easy kill. The trick is to have your tank keep him pointed in one direction. Also: don't get hit.
Shattrath City
We've spent a fair amount of time talking about the Hellfire Peninsula because, well, you'll spend quite a bit of time there around the middle of this month, but there's much more to the Outlands. Some of the areas you're bound to see early on are the Zangarmarsh, with its giant mushrooms and the Terokkar Forest, which holds a giant sanctuary known as Shattrath City.
Shattrath City is a central hub for the new continent and can be extremely useful for anyone who wants to explore the Outlands. There are portals to all the large cities and a place to bind and fly out of to the new areas of the game. Most people have been binding themselves in Shattrath and using it as a base of operations for exploration throughout the new world.
