Terestian Illhoof Boss Guide: World of Warcraft Karazhan Walkthrough

If you're looking for a World of Warcraft Karazhan Raid Boss Guide and Walkthrough for Terestian Illhoof, you've come to the right place!

Terestian Illhoof is an optional boss in Karazhan. Many people opt to skip Illhoof & Nightbane to go on to Shade of Aran. The trash mobs linked to Illhoof only consist of a single room full of imps, so it is easy to clear. Often times people come back later in the week to kill Terestian Illhoof. That being said he isn't that challenging once you've got some practice in and know how the fight goes, and he drops some nice loot.

Ideal Group Composition:

2 Tanks

3 Healers

1 Mage

1 Warlock

3 Other DPS

The Mage and Warlock are necessary in order to AoE down the imp adds that Illhoof summons. It is possible to do this with just one mage or one warlock, though they have to have good gear and be able to AoE really well. By this point in Karazhan your raid should probably be in at least half epics if you want to successfully down Illhoof.

There are several different important aspects of this single phase fight, so I will cover them one by one here.

Tanking

Illhoof needs to be tanked right in the center of the room by the main tank. The off-tank should pick up and tank Kil'rek, his named imp add, as soon as he shows up. If you have a paladin tank or a well geared/knowledgeable tank it is possible for them to tank both at once, though this isn't recommended when you're just starting in Karazhan.

DPS

This fight is all about the DPS. Illhoof is on a 10 minute Enrage timer - that means that he kills everyone if you don't kill him within 10 minutes. Your mage/warlock needs to continually AoE down the non-elite imp adds that Illhoof summons. Besides that, your other DPS needs to focus on Kil'rek when he is up. When they kill Kil'rek, they then attack Illhoof. Kil'rek respawns every 45 seconds or so, but when he is dead it gives Terestian Illhoof a debuff that makes him take 25% more damage, so it is generally worth killing him.

Terestian Illhoof also uses an ability called Sacrifice that all DPS need to be on their toes for. Sacrifice is the number one reason that people fail to down Illhoof. Periodically, Illhoof will draw someone to the center of the room, entangling them with demon chains. While they are in there, he will deal a significant amount of damage to them and also heal himself in the process.

All DPS need to have a simple macro set up: /target Demon Chains

This will allow them to quickly target the chains without having to click on them. This is very important, as it saves a lot of time in switching targets. As soon as Illhoof starts a sacrifice, all DPS need to immediately switch over to the Demon Chains. If Illhoof heals too much or you lose too many raid members to the Demon Chains, you will fail.

Healing

Healing actually isn't all that difficult for Illhoof. Your healers need to be on their toes and it can be mana intensive, however the primary healing in the fight will be done on the main tank, your AoE and any Sacrifice victims.

Besides that, this fight is just a matter of practice makes perfect. If you are having significant trouble with this fight, it is most likely because your DPS isn't strong enough. This can usually be solved by using better consumables, coming back later with better gear or using better raid specs.

Terestian Illhoof Tips & Tricks

- Mages' Ice Block and Paladins' Divine Shield can remove the character from Sacrifice.

- Druids can use Barkskin when they get Sacrificed to reduce the amount of damage taken.

- Paladins can and should put up Shadow Protection (Fire Protection if you have a second paladin). The only exception is if healers are having trouble with pushing by getting aggro from imps, in this case Concentration Aura should be used.

- Priests can use Fade right before Illhoof uses Sacrifice in order to prevent themselves from being the target.

- Hunters should drop Snake Traps as Illhoof will occasionally sacrifice a snake instead of a raid member. It is unknown if this is a bug or intentional and may be fixed at a later date.

- If you are having trouble with too many people dying to Terestian Illhoof's Demon Chains, you may want to have at least one of your healers use the following macro:

/stopcasting
/target Demon Chains
/target targettarget
/cast Regrowth

This will automatically heal whichever member of the raid is currently being Sacrificed. Of course, if you're not a Druid then you'll need to replace Regrowth with whatever your quickest cast healing spell is (Flash Heal, Flash of Light, etc.).
