Karazhan - Terestian Illhoof

Terestian Illhoof is an optional Satyr boss, located in The Repository in Karazhan's Library wing. He starts off with his minion, Kil'rek, and will summon more imps as the fight goes on.

Abilities

Terestian

• Melee: Hits for roughly 6,500 on cloth.
• Shadow Bolt: Terestian fires a shadowbolt at the target with the most amount of threat.
• Sacrifice: A random character is summoned to the center of the room and becomes paralyzed. They immdediately begin to suffer 1,500 unresistable (and unabsorbable) damage per second until the chains that bind the person (which count as a mob) are destroyed. While sacrifice is in effect, Terestian is healed for a high amount. The chains have approximately 13,000 health.
• Berserk: After 10 minutes, Terestian goes into a rage, and begins to spam shadowbolts that hit for 7,000 damage on the entire raid.

Kil'rek

• Melee: Hits for roughly 2,000 on cloth.
• Amplify Flames: An undispellable debuff that Kil'rek will place on the target highest on his threat list.
• Broken Pact: A debuff placed on Terestian upon Kil'rek's death. It causes Terestian to take 25% more damage.

Summoned Imps

• Melee: Roughly 400. Typically used if the target is immune to fire damage, or in close proximity.
• Firebolt: Inflicts 150 fire damage. Will inflict 650 damage if Amplify Flames is on the target. Has a very fast cast time.

General Tips

• Assign a Warlock or Mage to AoE the summoned imps. Warlocks are especially effect, due to Seed of Corruption, which should be spammed on Terestian continiously during the fight.
• If your raid uses a Mage to AoE the imps, bear in mind that both Fire Ward and Dampen Magic work well. Coupled with a Shaman's Fire Resistance Totem or a Paladin's Fire Resistance Aura, it can reduce the damage taken by a good deal.
• It is also recommended that whoever is in charge of AoE have decent fire resistance (200+) to help mitigate the damage that they will take from the imps.
• If two tanks are used for the fight, make sure the MT tanks Terestian inside the AoE, so that he takes additional damage while the imps are being killed.

Dealing with Sacrifice

• At least one healer should be assigned with healing whoever is chosen to be sacrificed.
• A Paladin would be especially useful for healing duty, since their Divine Protection allows them to bubble out of the sacrifice.
• A useful macro for switching to the chains is /target Demon Chains, or /tar Demon. This macro will allow you to switch targets quickly.
