History of Tomb Doomer

Overview

Tomb Doomer is an Episode: Revenant triumph in the Tomb of Elders category and a requirement for Slayer Baron. It awards 20 Triumph score for defeating the activity's unique bosses.

How to complete

Defeat each of the original four boss encounters: the Machinist, Sylok, the Defiled, the Lucent Hive fireteam, and the Psion Commander. Repeating a boss already defeated does not replace another missing encounter. Run Tomb of Elders or its longer Contest of Elders version until all four have appeared and been defeated.

Clear each room's objective to reach the boss. The Lucent encounter includes Hive Ghosts that must be crushed after their owners are defeated. Skolas in Kell's Vengeance is a separate encounter and does not replace one of this triumph's four bosses.

Availability

Tomb of Elders and Contest of Elders were vaulted on 15 July 2025. This original triumph and its seasonal title requirement are no longer obtainable.
