Kor’kron Dark Shaman is the 7th boss in Siege of Orgrimmar. It’s a multi-mob, multi-tank fight (3 >2) and is a bit of a clusterfrak of bad things on the floor that the raid needs to avoid.
Even through the Shaman share a health pool, my guild always tanks them separately (on normal and heroic) to make staying alive much easier, and I recommend that strat.
When the fight starts, you face not only the two shaman (Haromm and Kardris), but also their wolf mounts, Darkfang and Bloodclaw. The wolves do a nasty stacking bleed on their current target, so they should be burned down quickly. Keep all 4 mobs together until the wolves are dead so you can take advantage of cleaves.
Once the wolves are dead, send two tanks, the melee dps and most of your healers away with Haromm. My raid pulls him up the hill to the right of the building. Leave 1 tank, the ranged dps and a couple (or 1 on 10 man) healers to deal with Kardris.
Haromm’s side needs more healers because of Toxic Mist. That portion of the raid will also have to avoid a number of mechanics that can kill them very quickly – Foul Stream, Ashen Wall, and in heroic mode – Iron Tomb. It’s very important for the Walls and the Tombs to be positioned carefully so the raid doesn’t get boxed in and die a horrible death.
Kardris’s side also has a lot of bad stuff to deal with and will need to make the most of the space in the room. Toxic Storms are large purple swirlies which spawn on players and need to be avoided. The storms will also spawn Toxic Tornados which are smaller, but quick-moving. All ranged and healers should stay on one side of the tank so you can control where these spawn. Once you start running out of space, rotate around the room a bit until you have a clear area. Starting at 65%, Kardris will start summoning Foul Slimes, nasty little adds with a 3 yard aura that does heavy damage. Kill these asap, but don’t get too close to them. Periodically Kardris will cast Falling Ash. This creates a large red circle on the floor and after 15 seconds does very heavy damage to the whole raid (anyone actually in the red circle will be killed). The terrain can cause issues with seeing exactly where the borders of the Falling Ash circle are. The heroic mode mechanic is Iron Prison, which is cast on random players throughout the fight, dealing 100% of their health as damage after a minute. Damage mitigation cooldowns or shields are required to keep people alive through this.
At 25% the Shaman cast Heroism on themselves, increasing their damage and haste.
According to the top parses, BM outperforms SV on this fight. Maybe I’m just bad at BM, but I find this fight so much easier and my dps much better as Survival. The Foul Slimes are one of the biggest concerns for the ranged and I find them easier to mow down with hard hitting shots rather than my pet. But, YMMV.
Level 15 – Crouching Tiger, Hidden Chimera
This is more for heroic. You can get unlucky and get targeted by Iron Prison a bunch on this fight, so having Deterrence available more often is good. On normal, you might find the speed boost from Postehaste more beneficial.
Level 90 – Barrage
The cooldown on this lines up very nicely with the summoning of Foul Slimes.
Tips for the fight
- The bosses initially start off in a building and are a pain to get to. Do your raid a favour and reset them so they respawn outside. Don’t forget to dismiss your pet first.
- Use all your cooldowns and AoE/Cleave away while the bosses and their wolves are grouped up. Get those puppies down fast.
- If you happen to get hit by a toxic tornado (it happens), use a Healthstone immediately.
- Make sure Barrage is up while the Foul Slimes are spawning and also try to have an almost full focus bar so you don’t need to cast many/any Cobra Shots while they’re up. Start off with Multishot as they’re spawning and hit Barrage once they are all out. I generally don’t find dropping Explosive/Frost traps worth it. However, Binding Shot is great for keeping them still if you place it properly.
- You can use Deterrence to completely deflect the Falling Ash damage. You should definitely do this if you’re lower on health when it’s about to hit.
- On heroic, make sure Deterrence is up if you get Iron Prison – it takes a minute to deal its damage, so you have lots of warning. Use Deterrence when there are only a couple seconds left. It won’t completely negate the damage, it’ll just apply the damage reduction. It’s also a really good idea to use a WeakAura to let you know when you have the debuff and when it will expire.
