There are three locations aboard the Dreadnaught where you’re able to summon a secret boss named Vorok, Sentinel Eternal. Defeating him rewards you with the Willbreaker Shard: Vorok, which is required to complete the Rites of the Deep questline inDestiny 2: Heresy. Vorok, Sentinel Eternal can only be summoned once per Nether run – regardless of the location.
Before you begin your hunt, however, verify to pick up the Shattered Will: Vorok, Sentinel Eternal quest from the Shaping Slab in The Last City. This guide covers all possible spawn locations of Vorok, Sentinel Eternal, how to defeat him, and the rewards you can earn.

How To Find And Defeat Vorok, Sentinel Eternal
You cansummon Vorok in three locationsaboard the Dreadnaught:Mausoleum,Hall of Souls, andTrenchway. In each of these areas, you willfind three braziers that can be litto summon Vorok. However, these braziers can be a little tricky to locate. Despite being classified as a mini-boss,Vorok does not have much HP, making it fairly easy to defeat with almost any loadout.
Vorok can bedebuffed,takes additional Precision Damage, and is a relatively straightforward fight. Most burst-DPS Supers, such asChaos Reach,Thundercrash,Nova Bomb,Golden Gun,Needlestorm, etc. can easily one-shot him. As for his attacks, he does not have a lot of mechanics. Aside from hisstandard melee swings, he can also useStrand to pull you toward him. However, this abilitydeals minimal damage(even on Expert), so there is no need to worry about it.

We also recommend luring him away from other enemies in the area.
Additionally, verify to defeat him before the area’s boss, as killing the boss despawns everything else.

Once defeated,a chest will spawnnearby containingSigil Shards,Glimmer, andseasonal gear. You may also get aMinor Boonas an additional reward.

In the areawhere the Tormentor spawns, head to thefar-left side(from the spawn-point) to spot three braziers – two of which areon a platform extending from the main path. As before, light these braziers to summon Vorok, Excise Eternal.
