History of Grandmaster: Lake of Shadows

Overview

'''Grandmaster: Lake of Shadows''' is a Triumph in Destiny 2. It requires completing the Lake of Shadows Nightfall Strike on Grandmaster difficulty. Bungie's triumph text places it in Season of Arrivals. The strike is in the European Dead Zone on Earth and is a 1-3 player activity. The Season 20 (Season of Defiance) Grandmaster rotation listed it in week 12, May 16, 2023.

How to complete

1. Launch the Nightfall on Grandmaster difficulty.
2. The boss is Grask, the Consumed, a Taken Phalanx. It relies heavily on its shield to block damage, so strafe around it to reach its head.
3. The blight spheres are protected by shields that must be breached before they can be damaged.
4. Kill the Taken Goblins first. A Goblin can link with other Taken and make them invincible.
5. In phase 2 the perimeter becomes one large rift. Grask fires projectiles and a tether.
6. In phase 3 it summons Taken Goblins that can shield it.
7. Using a Super on Grask early lets it regenerate for the later stages.

Seal and reward

This triumph is one of the six Grandmaster Nightfall triumphs in the Conqueror seal. Completing all six awards Total Conquest automatically. The seal's other triumphs are Lightbearer, Breaker of Champions and Conqueror's Discipline. Completing the full seal unlocks the Conqueror title, which can be gilded once per season by completing every Grandmaster Nightfall of that season.

Availability

Grandmaster Nightfalls were removed in Update 9.0.0.1 with Destiny 2: The Edge of Fate on July 15, 2025. Nightfalls now run on a daily rotation covering all strikes and Battlegrounds, and The Portal offers Grandmaster-difficulty versions of PvE activities in their place.
