Blackwing Descent is a raid whose entrance is located in Searing Gorge in the World of Warcraft game. The minimum level for this dungeon is 85. The instance was released in the Cataclysm expansion. The raid contains 6 bosses. The end boss of Blackwing Descent is Nefarian.
Blackwing Descent is a Cataclysm raid where the entrance to the encounter is high up on a ledge on the outside of the Blackrock Mountain in Searing Gorge. If you have played the original Blackwing Lair, you will recognise that the end of that raid is the entrance of this raid.
The raid bosses drop 359 on normal and 372 level items on Heroic. It drops the same level loot as The Bastion of Twilight and Throne of the Four Winds raids. The final boss is Nefarian and his daughter Onyxia who we have both encountered before in the game.
You need to kill the first two bosses first before you can unlock the rest of the raid. If you miss the lift down, don't try to be brave and jump down as you will more than likely die. If you're a mage, don't use slow fall as you could quite easily miss the landing and fall into the lava and die or pull Onyxia.
When you enter the room, there will be three Dragonids in the room, one patrolling and the other two holding onto Magmaw. Carefully does it, pry the dragonids away from Magmaw and kill them all before you engage the boss. As the Dragonids are trash, you won't need to worry about adds or special moves.
As Magmaw has no arms, he relies on his breathe to fight you and will spit and breath fire onto your current location. When he spits, he'll sometimes summon a skeleton to fight you. In addition to the skeleton, he may release a group of slugs, nothing a mage explosion can't handle. The slugs because there are more of them are easier to kill.
During the fight, Nefarian will do some talking and be present in the fight in the sky as a black dragon. Nefarian might fire arcance fire balls as you but you will not be able to hit back, he'll be too far away to do any damage to him.
Toxitron is one of four that actually make up this boss encounter. All the other bosses are the same sort, a rock robot is possibly the best way to describe them. The others are Arcanotron, Electron and Magmatron. Their names give a massive clue to what they can do. Toxitron uses toxic poisons etc. Toxitron is the first to be encountered.
They are all on shared health so if you kill one, you kill them all. If their energy gets down to zero, they swap out and you fight another. There are no adds on this one so its one less thing you need to worry about.
If you are soloing it, its just a matter of simply nuking the golem where it stands, it won't affect you much in terms of health.
Maloriak is Nefarian's chief scientists. During the fight, he will run to his cauldron, grab a drink, drink it and then attack again. If you're soloing him, nuke him as quickly as possible.
Maloriaks' phases are time dependant rather than done by how much health he has left. The longer you allow him to live, the more adds that will come. He will create abberations and slugs during the fight which all have to be taken care of.
If you're soloing, be aware that he can freeze you and let the abberations kill you so don't try to show off by dragging on because it won't work.
When you first enter the room, there will be eight spirits of dead dwarves, four on each side of the room. You need to kill all the dead spectral ghosts first. When you pull one, all those ghosts that are on the same side will come. Only attack both groups at the same time if you are brave enough.
Once all the dwarves are dead, they'll be a spectral video to watch but if you're don't want to watch, walk up to the bell at the back of the room and click on it. The video will stop and Atramedes will fly down so move out the way. If you are doing this in a group, get the tank to move the boss into the centre of the room otherwise if you're soloing it, it doesn't matter where you are.
Atramedes is blink so he relies on sonar sound in the form of circles emanating out from his body in all directions. In the middle of the screen at the bottom is a small circle which will get brighter the more times you are hit by a circle.
During the fight, he'll summon adds to come your way so be ready with the offtank to pick them up or just simply nuke them when you get a chance.
When you arrive at the fight, the monster is sleeping and a gnome shouting for help, first things first. Don't worry about the gnome, he doesn't offer much in the grand scheme of things.
Sometimes the bile-o-tron at the back will walk round and sprout out poison, just avoid it. When the boss is dead, the bile-o-tron will break up.
The main thing to be worried about is Massacre which can kill everyone including very high level characters so if you're soloing it, you need to nuke it as quickly and efficiently as possible. When Chimaeron is dead, you won't be able to release the gnorme, just leave him in the cage and move on.
When you finally get to confront Nefarian, he'll be as a human in purple haze, if you go near him, you'll loose health. You need to look for the Orb which is at the opposite end of the room to unlock the haze and start the fight. You only need to do this once, if you wipe, he'll be flying around.
Stage 1 - Fight poor old Onyxia, during the fight, she'll create skeletons to help her, your priority is to kill Onyxia. If you are in a group, one group should deal with Onyxia, the other with the adds then whoever finishes first, help the others. Kill Onyxia and the adds will die.
Stage 2 - When Onyxia has been killed, you all need to swim/climb onto one of the three large objects spread out in the room. Each object has a humanoid rat like Maloriak on it. You only need to kill one of the rats to move to the next phase.
Stage 3 - Kill Nefarian in quickest and most efficient way possible and then the raid is finished. Loot and then get out.
