Grandmaster: Fallen S.A.B.E.R.

Overview

Grandmaster: Fallen S.A.B.E.R. is a Triumph worth 5 score in Destiny 2. It requires completing the Fallen S.A.B.E.R. Strike on Grandmaster difficulty. This triumph is tied to Season of the Chosen. The strike is set in the Cosmodrome on Earth and returned in Destiny 2: Beyond Light.

How to complete

1. Enter Rasputin's bunker in the Cosmodrome. Summon a Sparrow and follow the waypoint through the canyons.
2. The boss is S.A.B.E.R.-2, a Heavy Shank fighting in the Bunker War-4 arena.
3. At each quarter of lost health, the boss shields itself and summons Fallen adds. Defeat the adds to remove the shield.
4. At full health it fires a Solar Wire Rifle. The two cores in front of it are its weak points.
5. At half health it drops the rifle and cores and attacks with Void turrets. The weak spot moves to a glowing section on its front.
6. In its last segment it drops ranged attacks and chases players with a strong Arc melee. Its exposed core is the weak spot.
7. Arc Streams in the arena can deal significant damage, so they are a hazard during the fight.

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.
