For the Instructor Razuvious encounter in heroic Naxxramas, you need two priests. Typically, one is shadow and one is a healer. Because you’re awesome and thus shadow, this is the guide for you.

The boss is, in most situations, untankable by a player character. Instead, you need to use the Death Knight Understudy adds in the location. In the standard version of Naxxramas, there are two Obedience Crystals present. Using one of these crystals grants the player control of the respective Understudy. However, in heroic Naxxramas, these crystals aren’t present, and the adds must be Mind Controlled.

Before the encounter, ensure each of these conditions are met.

• You have at least 6% hit. You gain 3% from Shadow Focus (but not Misery, as it won’t be on the target!) and must gain 3% from gear.
• No paladins have Shadow Resistance Aura active.
• No death knights have Frost Aura active.
• No shamans have a Tremor Totem placed.

Each of these is believed to increase the chance of Mind Control breaking early. Mind Control is subject to heartbeat resists, meaning resistances are checked on intervals while you channel the spell, and not only when it hits. When the target is Mind Controlled and becomes friendly, it will gain all of the auras mentioned above, which increases the chance for Mind Control to resist.

Both you and your other priest should place Mind Soothe on their assigned Understudy to reduce the chance of accidentally aggroing it based on their proximity. Begin casting Mind Control, and let the games begin:

1. One priest will use the Understudy’s Bone Barrier ability. This is the sixth ability on your action bar and reduces incoming damage by 75%. It is necessary to use this ability to avoid getting killed by Razuvious.
2. The same priest will Taunt Razuvious. This is the fifth button on the action bar and forces Razuvious to attack you for 20 seconds. The cooldown of this ability is 20 seconds as well, and should thus be kept up whenever possible to avoid your DPS pulling aggro.
3. When the first priest’s Bone Barrier cooldown is half complete (that’s to say, has 15 seconds remaining) call out to the other priest to complete steps one and two. When their Bone Shield cooldown is half complete, they should call out for you to shield and taunt.
4. When Mind Control is nearly finished channeling, call out for an offtank to pick up the mob and release Mind Control and recast it. Time this so that the other priest will have enough time on Bone Barrier for you to be ready for your turn again. Needing to recast just as the other priest’s Bone Barrier fades can easily wipe your raid.

When Razuvious has been killed, the Understudies will begin taking an increased 5000% damage from eachother. One priest can release their add and the other priest can attack the now-released add to speed up the killing.
