- Xivu Arath.

Leviathan-Eater, Bane of the Ammonites (formerly known as Ir Uulxal) is a Hive Knight and champion of Xivu Arath. Known for killing the Leviathan that once graced the Ammonites, he would later be tasked with stealing the tithes to Eris Morn and to kill the Guardian in the process.

Biography
Once known as the Knight Ir Uulxal, he would be commanded by Xivu Arath to kill the Leviathan of Fundament and would succeeded at it, becoming the bane of the Ammonite civilization. He would be commended for his efforts and be renamed to the Leviathan-Eater and earned the title of Bane of the Ammonites.

Years later, he would be commanded again to steal the tithes created by the Guardian in order to empower Eris Morn to stop Xivu Arath. He would be summoned with a horde of Knights and Thrall near the end of their tithing and sought to test the strength of the Guardian and if they were a worthy challenge.

Gameplay
The Leviathan-Eater acts as the final boss of Mission: Conjure. He will first summon two Revenant Knights wielding Cleavers and Hive Shields, two Blistered Knights wielding Cleavers and a Warmonger Knight. He will teleport into the arena right on top of the Warmonger Knight, killing it in the process.

The Leviathan-Eater will appear with its Cleaver embedded into the ground and will stand up along with its summoned Knights and attack the player. He fights similarly to Zulmak and will stay at a distance while firing Fire Blasts as his Revenant and Blistered Knights fight for close combat. He will occasionally unleash a Sunspot on the ground, forcing the player to be on the move. It fought up close, he will slam his sword onto the ground, knocking the player away from his position.

Upon reaching five sixths of his health, he will summon in groups of Thrall along with more Revenant Knights. Upon reaching two thirds of his health, he will slam his sword into the ground akin to Zulmak activating his wipe mechanic and teleport away.
