This is part of a series describing rogue tactics for the bosses in Naxxramas. The focus is on the 10-man version of the fights, since that’s what most people will be running. If you have suggestions for alternate strategies, or if I say something that you disagree with, please put it in the comments.
These are not meant to be full raid strategy guides. They are written to describe the role of rogues (or other melee dps) during the encounters. For full strategy guides refer to Bosskillers or WoWWiki.
Finally, to Kel’thuzad. This is a pretty complex fight. It helps to have a well-organized UI. You will need to keep an eye on your character, your cooldowns, and Kel’s cast bar all at once. If you can use a UI mod to get all of those in your field of view, it will be helpful
Phase one of the fight is easy. The raid will run into the center of the room and fight off trash mobs that come from the perimeter. The skeletons are easy – often a Fan of Knives or a single melee atack will kill them. THe abominations get tanked and melee’d down. The banshees need to get burned down at range. A rogue’s job is to kill the abominations. You can go dps on the banshees also, but if you get too close to the walls you can pull more trash. Its best to stay near the center. Make sure the skeletons and banshees are dead before they get into the raid. They blow up.
Kel’thuzad will become active before the trash is dead. Let the main tank pick him up while ranged and AoE finish off the trash, and move onto KT.
Here’s where it is interesting. Ideally, everyone in the raid will keep 10 yards away from anyone else. That’s not possible if you have a bunch of melee dps, though.
Why do you need to separate? Kel’thuzad will throw out a Frost Blast. It hits a player and Ice Blocks him. Worse – it will chain to any other player within 10 yards. So you could conceivably get a whole lot of the raid ice blocked if you are bunched up, and that’s a wipe.
If you are near a few other melee, its not the end of the world. Stay ten yards away from the main tank at all times. If the tank gets ice blocked, its probably a wipe.
Players in an ice block will take 4 ticks of damage, each for 26% of their maximum health. That is 104% of your total health total. Your healers need to be fast and hit you with something quickly just to keep you alive. Instant casts or Flash heals preferred. It just has to be enough to keep you up through the fourth tick.
The best way to arrange melee is in a triangle or a square around Kel’thuzad. The main tank is at one point, and melee is at the other points. Each group is several yards away from each other group. That way, at worst one melee group gets ice blocked.
So you’re in your geometric arrangement dpsing away. Watch for void zones. You will see the red swirlies form, and you have a couple of seconds to get out before it blows up doing a ton of shadow damage and one-shotting you. Run or strafe quickly away from the tank and out of the zone. Don’t jump… run. If you jump you will still get blown up if you are in the air when the void zone detonates.
While you are maintaining your 10 yard distance AND avoiding void zones, you also want to interrupt KT’s frostbolts. They do a lot of single-target damage, so interrupting them will really help your healers keep the tank up.
On the 25-man version, Kel’thuzad will periodically mind control players in the raid. They need to be CC’ed until the mind control wears off, or else they will attack people, heal KT, and use their spells to cause havoc. It easiest to let your mage sheep them or your shaman hex them or your druid root them. You can possibly use Blind, or Vanish and Cheap Shot, but its better to leave it to someone who can do it from range. The MC is an aggro wipe as well, so use your TotT to help your tank re-establish aggro.
If watching void zones, maintaining distance, and interrupting frostbolts wasn’t enough… at 45% he will summon adds (2 adds on 10-man, 4 adds on heroic). They need to be picked up by off-tanks. At this point it becomes a dps race. Eventually the adds will kill the off-tanks and start running around taking out healers. So you need to down KT before that happens. Go all-out, pop your cooldowns, and burn him. Be prepared to use evasion if one of the untanked adds comes at you.
As I said at the top of the post, its useful to have your UI arranged for this fight. You need to see your cooldown timers to do your attack rotation properly. But you also need to look at your character on the screen to see the void zones. Finally, you need to see Kel’thuzad’s cast bar to interrupt his frostbolts.
When you get him down, you have access to some of the top gear in the game. The 10-man KT drops the T7 helm, the slow dagger Anarchy, and the Gem of Imprisoned Vassals (neck). There is Kel’thuzad’s Reach for fist spec rogues and the Nerubian Conqueror if there are no hunters grabbing it.
