Dul Arath, Retainer of Xivu Arath

Dul Arath, Retainer of Xivu Arath is a corrupted Hive Wrathborn general serving Xivu Arath, God of War. Sometime following its corruption, the Spider tasked the Guardian to end the Knight and put it out of its misery.

Gameplay
To track down Dul Arath, players must first place a lure at the Cryptolith found in the Divalian Mists.

The lure will attract a Hive Wrathborn Ogre. After depleting its health, it will abandon the Cryptolith and retreat. Players are then tasked with preventing its escape by locating its lair in the Dreaming City. A quest beacon will pop up and allow them to start the "Track the Wrathborn" activity. Players are recommended to read through the modifiers and be at Light level 1150+ before they begin their hunt.

The activity starts at the Garden of Esila, where players must defeat the nearby Hive before placing another lure by the Cryptolith. The Wrathborn Ogre will re-emerge with its depleted health and killing it will summon the boss.

Dul Arath, Retainer of Xivu Arath will spawn with an immunity shield alongside Wrathborn Revenant Knights. Killing these Knights will allow players to gain the "Wrathful" buff by standing inside the green pool they drop. This buff will enable them to damage boss's shield, as well deal extra damage to it. If players leave the pool or if it dissipates, the buff will last for four seconds before they have to get back in the pool or kill another Knight to spawn a new one. It is recommended that players remain in the pool for as long as possible and use long range weapons to counter Dul Arath's teleporting abilities and defeat the Knight for good.
