Bring Jin'rokh the Breaker a Primal Hakkari Girdle. You must also have a reputation equal to or greater than Honored with the Zandalar Tribe.
Jin'rokh the Breaker is located on Yojamba Isle, Stranglethorn Vale.
The ultimate vengeance waits within Zul'Gurub. Hakkar must not rise again. Hakkar destroyed the Gurubashi Empire from within. No sacrifice was enough. The trolls are a shadow of former glories. I know this is because of Hakkar.
Become the vindicator you were meant to be. Wreak havoc on the minions of evil. Zul'Gurub must taste Zandalar vengeance. Bring me proof in the Paragons of Power. You will receive the vindicator's belt. You will receive real power.
