This guide will show you how to complete Scarlet Keep at Grandmaster Difficulty.

The new season of Grandmaster Nightfall brings another rotation of strikes. One of the new raids released to the Grandmaster rotation is the Scarlet Keep, the giant Hive fortress on the moon. The arrival of this week's Scarlet Keep has challenged players to quickly complete the strike on Grandmaster difficulty.

Players who are new to this strike may find themselves in quite a difficult spot. Many have failed due to using the wrong combination of weapons, subclass and armor. But with the right setup, completing the tower on Grandmaster Nightfall will be easy.

Arbalest is the best recommended weapon you can use in Scarlet Keep. Since there are more barriers than unstoppables, it's important to have consistent anti-barrier damage in this save. Arbalest can also disposable elemental shields and deal pretty decent damage. Other weapons are Trinity Ghoul, Point of the Stag, Tyranny of Heaven, Linear Fusion Rifle and Blinding Grenade Launcher.
