Blade of Crota

A Blade of Crota is a gold-tinted Hive Knight major who appears in Old Russia and Ocean of Storms. These, unlike most Knights, have an Arc shield. When a Blade is about to spawn, the message "The minions of Crota have started a ritual" will appear for all players in the area. A circle of three Acolytes will appear at one of the area's Blade spawn locations. After a short time or if the circle is disturbed by a Guardian, the message "The Blades of Crota have invaded this world" will appear, and a Blade will spawn in the circle. The invasion party will then attack any Guardians or Fallen in the area.

When killed, Blades of Crota drop a Cleaver for use by Guardians. Blades of Crota also have a chance of dropping a Husk of the Pit.

The Blades of Crota were introduced in Update 1.1 just before the release of The Dark Below. The world event was removed in Update 1.2.0, but Guardians can still find Blades of Crota in the story mission Fist of Crota.
