Karazhan Terestian Illhoof Strategy

This fight used to be a joke but now he is actually pretty hard and requires a good paladin, a good warlock, and healers that are on the top of their game. The buff is his imps do more damage, he does more damage, his shackle heals more, and his shackles do more damage. This strategy has the Paladin and Warlock in the same group with concentration aura so the Warlock can hellfire next to Illhoof and his imp portals the entire encounter.

Placement

• MT - The only special placement is the tank, he needs to tank Illhoof right next to the middle of the room near the sacrifice spot so that when someone gets sacrificed DPS can just turn around and own the shackles.
• Warlock - The warlock should stand about to the left of where Illhoof is tanked, this is so his AoE is hitting both imp spawn points to pull aggro, hits Illhoof and his elite imp, AND hits the shackles when they appear.
• Healers/Casters - Just stand on top of the warlock so any loose imps can be hit by his AoE and hopefully aggro on him.
  Hunters - Should stay at close to max range on Illhoof so that when the shackles spawn you can DPS them with your good bow DPS and not crappy melee DPS.

The Encounter
The pull should be done by the MT running into the roof and grabbing aggro on Illhoof AND his elite imp. He will be taking a good amount of damage so all healers except the one assigned to healing the warlock should focus on healing him. Illhoof summons imps throughout the fight and has an elite imp pet which can be killed throughout the fight as well. If you kill the imp Illhoof takes a 25% increase damage taken debuff which can help on DPS for Illhoof. The pet can just be killed through moves such as blade flurry, cleave, and the warlocks AoE since he is tanked by the MT. He does not need to be focused. Every so often he shackles a random player and that player's shackles need to be killed IMMEDIATELY as it not only is a lot of damage a second to the player, but it heals Illhoof too.

In order to AoE down the imps just have a Paladin in with a warlock with concentration Aura on. Then have one person focus on healing the warlock while he does nothing but hellfire close to illhoof and will get aggro on all the imps. This keeps minimal imps up at a time, DPSes Illhoof's pet, the demon chains, and Illhoof himself. Also fel armor increases their healing received by 25%, throw in a tree form druid and that is another ~100 healing. The treeform druid can then just HoT up the warlock and assist the other healers on healing the MT and healing the shackled target.

DPS needs to be FAST on this fight, so as soon as the tank has aggro go balls to the walls DPS on Illhoof and like I said his pet can be killed throughout the encounter by using AoE type moves. I would not recommend trying to focus down the pet as it takes away DPS from Illhoof. His elite imp doesn't have that much health and his lesser imp adds have almost none either, just got to make sure you can keep most of them on the warlock. He also has a debuff which increases fire damage taken by 500...which can HURT due to his imp adds doing nothing but fire damage, but with the increased heals to the warlock and consant death of imps, it shouldn't be an issue. This should be a bit of a gear check for DPS and Healers but a rinse and repeat fight.

KEYNOTES

• Don't really focus on his pet imp, just DPS it with AoE style moves throughout the encounter.
• Make a macro that says /target Demon the shackles are called demon shackles and as soon as someone gets sacrificed you can use that macro you immediately start DPSing those down.
• The shackles need to be killed IMMEDIATELY as they heal Illhoof by a substantial amount and can kill people VERY quickly, the person who gets shackled should call it out so he gets immediate attention.
• Healers keep tons of HoTs on the warlock as he will take most of the healing, I would assign everyone to healing the MT and 1 person to focus on healing the warlock, if the warlock gets the flame debuff and the 1 healer is having trouble ask for temporary help from 1 other healer.
• You need your main tank to build aggro on both Illhoof and his Elite imp so give him a few seconds before unloading and AoEing.
• Without a Paladin and a Warlock this fight will be really tough because you won't be able to have the pally put on Concentration Aura which allows your warlock to cast hellfire the entire fight and your healers won't be interrupted either, Have the warlock stand in the middle of the room so his hellfire is doing DPS to Illhoof, his imp, the shackles, and his adds. You should have very little trouble with adds if you do this.
