Blackwing Descent is one of my favorite raids to solo. I¡¯m not really sure why, but I keep coming back week after week for some reason. Go figure!
10N: Pretty darn easy, actually. If your DPS gear is above ilvl 550 or so, you can speed things up by going Fury/Arms in Defensive Stance. Interrupt Arcanotron¡¯s Arcane Annihilator, avoid Toxitron¡¯s poison blobs and green puddles, and your survival is virtually guaranteed.
10H: Also pretty darn easy, at least at my tanking gear level (537). I haven¡¯t tried this fight in Fury spec/gear, since it seems hard enough to do so on 10N difficulty. DPS the active bot, stay out of pools and puddles, and collect some useless HEROIC loot! The main difference between 10N and 10H is that there is a ten-minute timer on the fight in Heroic difficulty.
25N: More of the same.
10H: All of the fun of Normal difficulty, with the added pleasure of self-destructing skeletal adds and constant meteor blasts courtesy of Nefarian! I didn¡¯t alter my strategy much from Normal, other than working in more cleave/AoE attacks for the extra adds and dodging the meteors.
25N: It¡¯s a fight against the 10-minute enrage timer. I did this fight in my ilvl 554 tanking gear, and still failed to kill Magmaw in the allotted time. Luckily, the increased damage caused by a Berserk worm sent my Vengeance soaring, and I was able to survive long enough to finish the job (with some help from a pile of defensive CDs).
10H: I had a really tough time dealing with the ten-minute Berserk timer. On my first successful attempt I actually survived a few seconds past the enrage, with some help from my defensive cooldowns. Aside from the extra damage Atramedes dishes out, the big change in Heroic is the addition of Obnoxious Fiends. These are little Fiends that are, well, Obnoxious. They attach themselves to your character (just like the Snobolds from Trial of the Crusader) and make loud noises, increasing your Sound very quickly. The only way to kill them is by Cleave/AoE damage: Thunderclap, Cleave, Revenge, Dragon Roar, et cetera are your friends here.
25N: no enrage timer for this fight; the main limitations are your patience (it¡¯s a 20+ minute battle) and the shield gongs.
10H: Mostly the same as Normal difficulty, with one catch: you don¡¯t get a nice long break from incoming damage when Chimaeron does his Feud attack. After about 5 seconds, Nefarian scolds Chimaeron and interrupts Feud, putting an end to the pointless bickering.
25N: Ouch! Unless your gear is near-godly, you¡¯ll need to be a master defensive cooldown manager to survive into Chimaeron¡¯s enrage. Doing so will send your Vengeance soaring (mine hit 620k), which will give you the DPS to finish off this hideous monstrosity.
10H: Ouch. This fight is one of the hardest I¡¯ve ever tried to solo, ranking up there with Ultraxion on the difficulty scale. Let¡¯s break it down by phases:
Silence is Golden: This one is MUCH easier to do on Normal difficulty. Simply avoid the major sources of Sound, and you should get it.
Keeping it in the Family: Basically, ignore Onyxia, focus exclusively on Nefarian, and hope you get him down to 50% before Onyxia self-destructs.
Full of Sound and Fury: Are you soloing Chimaeron If so, this one is a freebie!
Blackwing Descent: Clear the raid, get an achievement!
Heroic: Omnotron Defense System
Heroic: Nefarian: If this is your first Heroic Nef kill, you¡¯ll get the title ¡°Blackwing¡¯s Bane¡± along with the achievement.
