Darkblade Harvester

Overview

Darkblade Harvester is a buff claimed on the Moon in the Beyond mission, by defeating the Bestowed Darkblade. It is the middle step of the Above and Beyond triumph, which asks you to find and kill the Darkblade, claim the buff, then finish Beyond without dying. Beyond is a Shadowkeep Moon mission that can only be replayed when it is featured, and guides describe it as a legacy mission that rotates back in periodically.

Acquisition

Find the Bestowed Darkblade, a yellow-bar Knight in the last set of caves before the drop into the chasm with the Pyramid. Drop into the cave lit by green crystals and clear the Acolytes and Knights there, but do not advance. Wait, and the Darkblade slowly walks toward you. Stay near the right wall from the entrance and use ranged weapons. The buff is applied automatically when he dies.

Triumph

After claiming the buff, complete Beyond without dying. Any death resets your progress on the triumph. Three bosses are shortened versions of standard fights: Ghaul, whose immunity only goes up once; Fikrul, who summons a lightning field over a small group of Scorn; and Crota, the hardest, where you need to get close enough to use the sword while his minions attack from range. Reach the robed figure at the end and interact with the spherical artifact to finish the triumph.
