History of Harrow

Harrow, Dredgen-Apprentice is a Cabal boss in the Equilibrium Dungeon from Destiny 2: Renegades, a Gladiator wielding dual Praxic Blades. He fights aggressively, teleporting and forcing movement. Sources disagree on his slot: one guide calls it the first boss fight, others (and encounter-specific guides) the second.

Encounter

The fight builds on the dungeon's Shadow Power system. Guardians gather darkness from Lackeys and Taken wells to climb from Shadow Novice to Shadow Apprentice, then use the Shadow ability on darkness-protected panels (three per side room, shown by green lights over doors).

Harrow's shield breaks two ways: lure him onto the red bay doors and shoot the fuse to drop him through, or have him hit the electrical pylons so they discharge. Each damage phase lasts roughly 30 seconds, and the fight ends when he breaches the back wall. Burst weapons such as Praxic Blade are recommended.

The Way Between

The quest The Way Between has you follow the intended dungeon path down the shaft to fight Harrow before its repeat clears and secret relics.
