Coming up in patch 2.3, as most people would be aware, is a new 10-man raid instance to follow on from Karazhan: Zul’Aman. It’s another troll instance, in the fine tradition of Zul’Farrak and Zul’Gurub, populated by animal god bosses (the loas) and their worshippers. It’s meant to be a fast, fun instance for reasonably advanced casual guilds: it can be cleared in a few hours, there’s extra quest rewards for clearing it within a set timespan (think of the old 45-minute Strat Dead runs; same sort of deal) and it resets every three days.
To get a bit of an idea of what’s required, my guild went and gave it a bash on the Public Test Realm last weekend. It was certainly… educational. And bloody.
He’s a pretty tough boss, and needs two tanks to fight him. The tanks taunt him betwen them – one for troll phase, one for bear phase – and while he’s busy tearing new holes in them, the DPS kill him. He does some nasty DoT bleeds during bear form, and a silence, and a charge, and a two-target cleave, but he’s fairly simple. From a raid coordination perspective, he’s probably closest to Attumen in complexity; he’s certainly easier, strategy-wise, than Netherspite or Aran or the like. Gear-wise is a different story; he’s got about 1.7 million health and does high DPS, especially to the tank for the bear form phase. Our raid team was pretty much fully Kara-geared, but I suspect you wouldn’t need to be quite that well-geared; a cohesive team that can reliably do Illhoof-level bosses can probably do him, provided one tank is very well geared. A team with undergeared tanks is going to be in serious trouble, simply because Nalorakk puts out so much damage, particularly in the bear phase*.
(You can find more details about the strategy for fighting Nalorakk here at WoWwiki.)
And here you can see his inevitable death scene: we killed him on our second night, when we had a more suitable raid composition. It’s a fun and relatively easy boss fight, and certainly a good introduction to the zone; we didn’t have time to try the next boss, but word has it that the difficulty level on boss fights ramps up very quickly.
* Also, on a specific strategy note, Nalorakk does a 2-second silence during his bear phase, which can often lead to tank deaths, so having your healers maximise their HoTs during this period is a good idea.
