Bring Jin'rokh the Breaker a Primal Hakkari Kossack. You must also have a reputation equal to or greater than Revered with the Zandalar Tribe.
Jin'rokh the Breaker is located on Yojamba Isle, Stranglethorn Vale.
The vindicator's symbol of power is the breastplate. It is forged with powerful mojo. It is trusted only to those we revere. It is the Zandalar symbol of vengeance.
To become a vindicator is to become vengeance. Take the Paragons of Power we need from Zul'Gurub. Bring them to us. We will take the mojo stolen from us. We will make the minions of Hakkar pay. We will reward you with the vindicator's breastplate.
Go. Be our vengeance, <name>.
