History of The Great Usurper

Overview

The Great Usurper is a Monument of Triumph raid challenge involving Calus. The objective continues after the boss defeat: players must enter his reward area and view the assembled Calus robots.

How to complete

Complete the Calus encounter in Pantheon. After the kill, follow the route into the room containing the rows of robot duplicates and collect the reward chest there. Stay with the fireteam through this final room rather than departing from the boss damage arena immediately after the kill. Entering the robot room and collecting its drops completes the post-boss objective.

Claim the completed record through the Monument of Triumph interface.

Rewards

Claiming the Monument of Triumph challenge grants 50 Legendary Marks and unlocks a reward at the Tenet of Death.
