Elder Nadox Elder Nadox , a Nerubian vizier , is the first boss found in , located within the Hall of the Conquered Kings . He is a servant of the Lich King and guardian of the nerubian eggs . Abilities . Elder Nadox periodically summons adds during the fight . Among these adds is a Guardian which has an 80 - yard aura that causes Elder Nadox and the adds to become immune to all types of damage ; to remove the immunity the group must kill the Guardian add , at which point the boss and adds will become vulnerable again . Elder Nadox also has the ability Brood Plague which diseases the enemy causing 12750 nature damage over 30 secs ( normal ) and 25500 nature damage over 30 secs ( heroic ) . Heroic . Similar to Normal , when a Guardian spawns , the boss and adds become invulnerable to all attacks until the Guardian is killed . This causes complications for the tank attempting to hold aggro on the adds , as a zerg rush on the healer will almost always occur . It is advised that someone be appointed to taking out the adds that aggro the healer ( while they are still vulnerable ) so as to make sure as few are alive as possible when the Guardian makes them immune . The tank must continuously taunt off of the healer , and perform any other actions possible with taunt or heal mechanics during this immunity , as standard tanking moves which create threat from damage are entirely useless while the Guardian is up . After the tank has aggroed the boss , the healer should position himself at the wall behind the boss , so that the adds will need to walk a longer distance before reaching the healer . Guardian Adds : Heroic . Designate a single non - slowing , ranged DPSer to bring the guardian to the tank . At the first possible opportunity the tank needs to grab the Guardian ' s attention so the DPS can open up on it . The idea is that the DPS need to stay as close to the healer as possible in order to clear off any adds that healer - zerg once the guardian dies . Tactics for Various Party Configurations in Heroic Mode . Paladin tanks Pally DPS A Paladin healer nearly eliminates this difficulty in this fight , as they can Divine Shield or Blessing of Protection themselves to drop aggro on the adds . Warrior Tank Warrior DPS Death Knight Tanks Death Knight DPS Priest Healers Druid Healers Achievement Method . Note : As of patch 3 . 0 . 8 , the following method is no longer usable ( Elder Nadox will enrage with a 500 % increased damage buff if he is kited out of his room and will 1 - 2 shot the tank thus wiping the group ) . Confirmed . In order to get the special heroic achievement , a lot of moving is needed . Position the DPS at the start of the instance , away from the Elder ' s room . The tank then pulls Elder Nadox , the healer keeping the tank topped off . The tank leads Elder Nadox to the entrance of the instance , and the DPS can start . This causes no adds to spawn . This is due to the fact that the party is so far away from boss room that the adds will not be able to find the party . This causes them to despawn almost as quickly as they spawned . Note : The immunity granted by the guardian adds acts as an aura ; offtanking them far away cancels the immunity . An experienced kiter can pick up one of these , leaving the group alone with the boss ; thus you need to bring quite impressive DPS in order to down Nadox in time . Increasing the kiter ' s movement speed helps a lot . Another tactic is to kite the boss through the door to his right , down the balcony overlooking the grounds before the second boss . Tank him in the farthest end of the balcony at the base of the stairs . Have a Hunter CC the Guardians where they spawn , or let someone offtank them and nuke the boss as fast as possible . Elder Nadox will not enrage if he is at the base of the stairs .
