Zul’Gurub is a 20-man raid located in the northeastern portion of Stranglethorn Vale, east of Lake Nazferiti. Tier Set Gear does not drop in Zul’Gurub, however there are class-specific armor sets available that all contain five pieces of epic quality gear. All of these set pieces are available through quest rewards and reputation requirements with Zandalar Tribe. The set pieces themselves are not from boss drops inside Zul’Gurub.
Hundreds of years ago, Zul’Gurub served as the capital city for the Gurubashi Troll Tribe, however, it was eventually destroyed by civil war and corruption from within. Centuries later, Atal’ai Priests have reclaimed the city for their own evil deeds, with the intention to summon their Blood God, Hakkar, who is the final boss of Zul’Gurub.
