Shadowfang Keep

The Cell Keeper guards the keep's prison, where Deathstalker Adamant and Sorcerer Ashcrombe are locked up. Kill him, then talk to your faction's prisoner: Adamant for the Horde, Ashcrombe for the Alliance. Your prisoner opens the courtyard door, and that door is the only way on. Horde players: Adamant is one of the two deathstalkers that Deathstalkers in Shadowfang sends you to find. Rethilgore's Soul Drain roots a player for 10 seconds while it drains their health into his, so interrupt the 2-second cast or dispel it.

The keep's butcher drains mana from his target with Butcher Drain, so a tank who fights on mana should start the pull full. Let the tank build a threat lead before anyone opens up. He drops Butcher's Cleaver, a fast one-handed axe with Strength.

The keep's dead lord casts Veil of Shadow, which cuts the healing its target receives. When it lands on the tank, heals barely land until it fades, and that's the dangerous window. It's a curse: a Mage's Remove Lesser Curse, from 18, or a Druid's Remove Curse, from 24, strips it.

He drops Baron's Scepter, a mace that makes every party member near you regenerate health.

The undead commander heals himself with Holy Light. Interrupt every cast and he dies quickly; let the heals through and the fight drags on. He also stuns with Hammer of Justice, so have a second interrupter ready for when the first one is stunned. Divine Shield makes him immune to damage and spells for 10 seconds, so wait it out. He drops Arced War Axe, a two-handed axe with Strength and Stamina, and Commander's Crest, a tank shield.

Odo grows more dangerous as he loses health: each time he howls with Howling Rage, he gets stronger. He also calls every creature within 30 yards when pulled, so clear around him first. Save your cooldowns for the end of the fight and finish him fast.

He drops Odo's Ley Staff, a staff with a big healing bonus.

Fenrus is a huge wolf. His Toxic Saliva is a poison that burns his target and drains their mana for two minutes: cure it with Purify or Cure Poison. Tank him away from the group and burn him down. He drops Fenrus' Hide, an Agility cloak, and Black Wolf Bracers, leather bracers with Stamina and Attack Power.

Nandos is the last stop before Arugal. Lupine Horrors prowl near him: clear them before you pull, so he fights alone. The longer the fight runs, the more worgs join him, so burn him down quickly. He drops Wolfmaster Cape, a cloak with Attack Power, and Feline Mantle for casters.

Arugal teleports around his chamber, so the fight keeps moving. He throws Void Bolts, stuns everyone near him with Thundershock, and uses Arugal's Curse to turn a player into a worgen that fights for him for ten seconds.

Spread out, keep the healer away from him, and never kill a cursed party member: wait out the ten seconds. His head completes Arugal Must Die, and he drops Meteor Shard, a dagger with a Fire damage proc.
