Magitheridons Lair is an one boss raid encounter in Hellfire Peninsula. You make your way through the trash and then fight against the Pit Lord boss before he can escape after wiping you all out. You need to work through the raid killing the Twilight Practitioners before you can fight Magtheridon. Only when the Twilighters are killed can you fight the boss.
When Burning Crusade came out, you could only do Magtheridon's Lair after you had completed a quest chain which involved running a few Hellfire Citadel dungeons at max level and in a short time. The pre-requesite no longer exists, you can enter the dungeon at any time and take on Magtheridon. There is only one boss and one achievement to be had so once its done, no point in coming back.
Magtheridon's Lair entrance is located on the west side of the wall and on bottom rather high up like the dungeons. When you kill the boss, a quest item drops along with a 20 slot bag. One person per raid will get the bag and the quest item.
There's only one reason to come here and that's kill Magtheridon, once he's dead, there's no point in coming back. There is only one achievement to be had here and that's to kill him. There are three phases to this boss but the second and third are essentially the same.
The fight starts as soon as you hit one of the wardens holding him in place. The minute you hit, all the wardens will come and hit you. The wardens will use a mix of solo and AOE damage. They'll also use fear tactics so be the best course to use against them is to use A.O.E. damage otherwise you'll find it difficult to take them out individually.
Once all the trash have been killed, Magtheridon will start making his move. The second and third moves are the same. If you're high enough, Magtheridon's third phase is nothing and he'll die immediately.
