Disciple of Harrow

Disciple of Harrow is a Cabal Colossus of the Barant Imperium and a disciple of Dredgen Harrow. It is the final boss of the Fire and Ice Exotic mission in Destiny 2: Renegades, and it stands between the Guardian and their Praxic Blade.

Fight

The fight uses the energy orb mechanic from earlier in the mission. Light and Dark Blights sit in the arena. Guardians fill orbs by defeating enemies in pairs: two normal Cabal or two Taken Cabal in a row makes a Light orb, and one of each in a row makes a Dark orb. Throwing an orb into a matching Blight grows it, and both Blights need to grow at a similar pace. The Disciple can be damaged through the first three quarters of its health while enemy waves keep spawning. At the final quarter it gains a shield, which drops only when the Blights are balanced. The Octants in the arena change which enemy types spawn.

The Disciple fires an Imperium slug thrower that deals Solar damage. Its abilities include Immunity Shield, Kinetic Quake, Summon Cabal, Summon Taken, and a portable Cabal shield.

Rewards

Finish off the remaining enemies after the Disciple falls to receive the Praxic Blade, an Exotic sword.
